Overview 1.0 Overview The ME-ARC remote control allows you to monitor and customize the operating parameters for your Magnum inverter/charger. This remote can be used on all Magnum inverter/charger models so there is no cross-platform confusion. The ME-ARC50 comes standard with a 50-foot, 4-conductor (twisted-pair) telephone cable and includes non-volatile memory (preserves adjustable settings, even if power to the remote or inverter is removed). Info: This manual is for a ME-ARC with software version 4.
Installation 2.0 Installation Review this section and the Important Product Safety Instructions on page ii before proceeding with the installation of your remote. WARNING: Installations should be performed by qualified personnel, such as a licensed or certified electrician. The installer determines which safety codes apply and ensures all applicable installation requirements are followed. Applicable installation codes vary depending on the specific location and application.
Installation 2.2 Connecting the Remote Cable The ME-ARC comes with a remote cable to enable communication between the inverter and the remote. The cable is a 50-foot, 4-conductor, round twisted-pair, telephony standard with 6P4C (6-position/4-conductor) connectors on each end. When the 6P4C connectors are held side by side with both of the connector tabs facing the same way, the color of the conductors in each connector is the opposite from top to bottom (as shown in Figure 2-1).
Installation 2.3 ME-ARC Remote and Bezel Dimensions Use the information below (Figures 2-3 and 2-4) in preparation for mounting the ME-ARC remote and the bezel (if applicable). Directions for mounting both follow in Section 2.4. ~1⅝" (4.1 cm) 5 ¼” (13.3 cm) ~1" (2.5 cm) 3 ¼” (8.3 cm) 3 ⅞" (9.8 cm) 2 ¾” (7.0 cm) .9" (2.3 cm) 1 ⅛” 5 ⅞" (14.9 cm) (2.9 cm) 1 ½” (3.8 cm) Figure 2-3, ME-ARC Remote Dimensions ~1 ½" (3.8 cm) 5 ⅞" (14.9 cm) 5 ¼" (13.3 cm) 4 ⅜" (11.1 cm) 2 ⅞" (7.3 cm) 2⅞" (7.
Installation 2.4 Mounting the ME-ARC Remote The ME-ARC can either be flush mounted (through an opening in the wall), or surface mounted using the provided bezel. Find a location that is clean, dry and protected. Allow room to access the remote’s SELECT knob and to view the LEDs/display. CAUTION: Ensure that no AC power is connected to the inverter, and then according the your inverter owner’s manual correctly connect the inverter to the batteries.
Installation 2.4.2 Surface Mount Installation Procedure To surface mount, you must use the supplied bezel (Figure 2-4). 1. 2. 3. 4. 5. 6. 7. Info: The bezel has tabs at the bottom and side that are made with thinner material (Figure 2-4). They can be cut or broken out to allow the cable to be routed downward or to the side (Figure 2-6). Using the bezel as a template, mark on the wall the location of the four bezel mounting screws, and then drill pilot holes for the #8-32 screws.
Installation 2.5 Power-up Self Test Info: All power to operate the remote control is provided by the inverter/charger through the remote cable. When the ME-ARC is first connected to an inverter, a power-up self test is initialized. During the self test, the LCD automatically displays in sequence: • “MAGNUM ENERGY Self Test”, then • “(C)2010-2013, Connecting to...”, and then • “ME-ARC V 4.0, INV/CHG V #.#” The remote’s LEDs also change with the screens (see Figure 2-7).
Setup 3.0 Setup When the remote is connected to a Magnum inverter/charger, the settings in the remote control determine the inverter/charger’s operating parameters. The default settings in the remote control are adequate for most installations (see Table 3-3); however, you have the option to change some of the operating parameters. This section shows you how to navigate the remote and gives you an understanding of the function of each adjustable setting. 3.

Setup 3.2.2 CTRL (Control) Button and Menus The CTRL button accesses the 01 ACIn Control, 02 CHG Control, 03 Gen Control and 04 PT Control menus. Info: An AGS controller or PT charge controller must be connected in order for those device-specific menus under the 03 Gen Control or 04 PT Control settings to display, respectively—unless the TECH: 07 Show all Menus menu has been set to “YES”. Refer to Section 3.2.5 for more information on the TECH 07 menu.
Setup CTRL: 01 ACIn Control 01 ACIn Control menu has four different conditions in which the inverter/charger will connect to an incoming AC power source. Only one may be selected at any one time—multiple conditions can be enabled, but only one can be active.
Setup CTRL: 02 CHG (Charge) Control 02 CHG Control enables you to set the charge mode to Multi-Stage, Start Float, or to Start Bulk. Generally, the charger should be left in the Multi-Stage setting, but to override this setting use the CTRL button and the 02 CHG Control menu. The charger can be forced to start the Float or Bulk mode using the Start Float or Start Bulk settings from the CTRL: 02 CHG Control menu.
Setup 3.2.3 METER Button and Menus The METER menu button gives you access to the various meters that determine the status of the inverter/charger and battery system (AGS, BMK, ACLD, and PT controller also if connected). Info: Depending on the inverter, some meter functions may not be accessible. Refer to Appendix A for more information. Info: Most displays automatically return to the remote’s home screen five minutes after the last button push.
Setup • 02B Load Amps (MS-PAE, MS-PE and MSH models only) – This meter displays the total AC current delivered to the loads on the inverter’s AC output terminals. A positive (+) Load Amps value indicates power is being pulled from the inverter to run an AC load—either using the batteries in Inverter mode, or from the AC input source in Standby mode.
Setup INVERT MODE Current from the battery is used by the inverter to power the inverter’s AC loads. Example below: Current to inverter input (AC Input) = 0 Amps AC Current from battery (Inv/Chg Amps) = -10 Amps AC Current to power the AC loads (AC Load) = 10 Amps AC 02C Input Amps 02D Inv/Chg Amps 0 Amps AC -10 Amps AC AC Input = 0 Amps AC DC CURRENT (BATTERY) -120ADC AC CURRENT (GRID/GEN) MAGNUM INVERTER A FROM BATT .
Setup METER: 03 Timers • 03A Charge Time – This meter displays the total time the charger is holding the batteries at a high voltage level—defined as 0.2 volts greater than the float voltage setting. The timer counts when in the Bulk, Absorption, or Equalization charge stages (or in the Constant Current and Constant Voltage charge stages if CC/CV is selected under the SETUP: 03C Battery Type menu). The meter does not accumulate time when in Float, Charger Standby, Full, or Silent mode.

Setup • 01C Temp Display – This menu item selects whether to display temperatures in Fahrenheit or Celsius. Once you select either Fahrenheit or Celsius, the following menu items will use your selection: the METER: 04D AGS Temp menu, the SETUP: 04E Gen Run Temp menu, and the TECH: 01 Temperatures menu.
Setup Where should I set Search Watts? The Search Watts setting should be adjusted to the same power level (or the next lower setting) of the smallest load that you plan to run. If you don’t know the wattage of the smallest load, turn the switch for the load on and decrease the Search Watts setting until the load comes on and stays on. Info: Even though the Search Watts feature is on, some connected equipment—even if they are off—may draw enough current to keep the inverter in Inverter mode (i.e.
Setup • 02C AC In - Time – This feature allows you to connect to the local power utility at a predetermined time of day. When the current time falls within the set times, the inverter/charger connects to the AC that is connected to the AC input terminals. Once outside the set times, the inverter/charger disconnects from the AC source.
Setup Where should I set AC In - VDC? Check with your battery manufacturer to determine the correct settings for your batteries. Typically, manufacturers do not recommend discharging the batteries below 50% (i.e., a voltage setting of approximately 12.0-12.2 VDC, 24.0-24.4 VDC and 48-48.8 VDC for 12, 24, and 48-volt batteries, respectively). To protect the batteries from overdischarging, set to 12.2 VDC (12v), 24.4 VDC (24v), or 48.8 VDC (48v).
Setup Notes on using the AC In control settings based on VDC or SOC: 1. The AC In - VDC or AC In - SOC settings allow you to optimize the use of another energy source (i.e., solar, wind, and/or hydro), and only allow the use of the utility power when the energy source is not able to keep up with the load demands under normal conditions (i.e., cloudy day). 2. The energy source should be sized to meet the daily power requirements of the loads being operated under normal conditions.
Setup CAUTION: Unless you have an MS Hybrid Series inverter/charger—which has the Load Support feature—the AC Input Amps setting only limits the current to the battery; it does not limit the current to the inverter loads. If the current from the loads on the output of the inverter is greater than the circuit breaker rating on the incoming AC source, you will experience nuisance tripping.
Setup Settings for MSH4024RE: Info: The MSH4024RE is a dual input source inverter/charger having two independent AC source inputs (AC1/GRID and AC2/GEN) with independent VAC Dropout settings for each input. The Set VAC Dropout menu only displays both the AC1 and AC2 fields if the remote is connected to a MSH4024RE model. ◊ Set VAC Dropout (AC1 and AC2) – The AC1 setting determines at what AC voltage—from the AC1 to NEUT terminals—the inverter/charger will connect to or disengage from the incoming AC.

This is for a system that requires a constant charge voltage to be present at all times (see Figure 3-11).
Setup • 03D Absorb Done (Time, Amps, SOC) – This setting identifies whether time, amps, or SOC are used to determine when the second stage of battery charging (Absorption) is finished. The charge cycle transitions to the final charge stage (03G Final Charge Stage) afterwards. Absorption is the second stage of the charge process that attempts to fully charge the batteries.
Setup ◊ Set Absorb Done (SOC) – This setting can be used if a battery monitor kit is installed and you want to use the SOC (State of Charge) of the battery bank to determine when the batteries are fully charged. During the Absorption charge mode, once the METER: 05B Battery SOC menu reaches the Absorb Done SOC setting, the charger transfers to the final charge stage (see 03G Final Charge Stage).
Setup CAUTION: The C/5 or C/20 charge rate settings are not requirements on how to set your battery charge rate. For specific charge rate requirements, refer to your battery manufacturer. CAUTION: If multiple inverter/chargers are used on a single battery bank, ensure that the total charge rate from all inverter/chargers is limited to the maximum charge rate needed for your battery bank. The Max Charge Rate setting only limits the charging on each inverter/charger individually, not on all inverter/chargers.

Setup Info: When Multi is selected and the charger goes to Full charge mode, if another charge source (such as PV or wind) is charging the batteries above the fully charged voltage, the charger will remain in the Full Charge stage. Why should I use Multi? Multi is the most commonly used charge mode. It is suitable for most applications and assures a full charge to the batteries, without overcharging.
Setup 3.2.5 TECH Button and Menus The TECH menu button provides access to selections that are used to assist service technicians in troubleshooting. It also provides access to system information along with a selection that allows all system settings to be returned to their original factory default values. See Figure 3-15 below.
Setup TECH: 03 Inv Model Displays the model number of the connected Magnum inverter. Info: When the 03 Inv Model menu item displays “Unknown”, the remote is unable to determine the inverter model. This happens when the remote is connected to a later/ newer inverter model not recognized by an older remote. All remote menu selections and features that are available in the inverter will function normally. Info: When an inverter is stacked in parallel or series, a stacking indication follows the model number.
Setup TECH: 05 SETUP PIN This menu sets the password (PIN – Personal Identification Number) and locks/unlocks the ARC’s SETUP button menus. Why should I use the PIN feature? Restricting access to the SETUP menus with a password can avoid unauthorized changes to your settings by inexperienced users. Setting a PIN (unlocked SETUP button) If a PIN has not been set, the SETUP menus are accessible to everyone (i.e., SETUP unlocked).
Setup Resetting/Clearing a PIN You can override a previously entered PIN. When “PIN = 0***” displays, press and hold the SELECT knob until “PIN = 0000” displays (approximately 7 seconds). Enter a new PIN number. TECH: 06 Ext Control External Control is a read only menu. Magnum Energy has adopted an open protocol policy which allows certain functions of the inverter/charger to be controlled externally—such as with a third party communications device.

Operation 5.0 Operation This section explains how to operate the inverter/charger using the ME-ARC remote. It also provides information on the LED indicators and the LCD display that are used to show the operational status of the inverter/charger. 5.1 Front Panel The ME-ARC’s front panel contains LED indicators and a LCD display for viewing system status, buttons to control system operation, and a rotary knob that enables you to locate and select system information and settings.
Operation 5.1.4 Menu Buttons These five buttons provide quick access to menu items for configuring, monitoring, and troubleshooting your inverter/charger system. • FAVS – This button allows five menu items to be stored for easy access without having to find them within the SETUP or other buttons. The five items stored under the FAVS button become the “favorite” menus that are most often used. For more information, see Section 3.2.1.
Operation 5.2.2 Charger Mode Turning the charger on: The charge mode is automatically activated and begins when acceptable AC power (utility/generator) is connected to the input of the inverter. When in charge mode, the display may show: Charging, Bulk Charging, Absorb Charging, Float Charging, Full Charge, Silent, Charger Standby, Force Float, Equalizing, Load Support VDC, and Load Support AAC.
Operation 5.3.1 Inverter Mode Status Messages There are six Inverter mode messages. View the top line of the LCD display and the corresponding message in this section to identify and understand the particular Inverter mode. • Inverting – The inverter is providing AC voltage on its output by inverting power from the batteries. • Inverter Standby – The inverter is on but not actively providing power.
Operation Info: Press the ON/OFF CHARGER button to enable charging again. When enabled, the charger continues in the previous charge mode and the CHG (green) LED comes on. • Charging – Once Charger mode has been enabled, the unit waits and displays “Charging” to determine the charge routine. If the DC voltage is low (≤12.8 VDC/12v models, ≤25.6 VDC/24v models, or ≤51.2 VDC/48v models), the charger initiates bulk charging. If the DC voltage is high (≥12.9 VDC/12v models, ≥25.7/24v models, or ≥51.
Operation • Full Charge – This status indicates that you have entered the Battery Saver™ mode. This mode maintains the batteries without overcharging, and prevents excessive loss of water in flooded batteries or drying out of GEL/AGM batteries. After four hours of float charging, the charger turns off and “Full Charge” displays (charger is now in Battery Saver™ mode). If the battery voltage drops to ≥12.6 (12-volt models), ≥25.2 (24-volt models) or ≥50.
Operation • Time Connect – AC power is present at the inverter’s AC input, but the time of day needs to fall within the Connect time and the Disconnect time settings per the SETUP: 02C AC In - Time menu in order for the inverter/charger to connect to the incoming AC. • VDC Connect – AC power is present at the inverter’s AC input, but the battery voltage needs to fall below the Connect Volts setting from the SETUP: 02D AC In - VDC menu in order for the inverter/charger to connect to the incoming AC.
Operation • FET Overload – This fault message indicates the inverter/charger was running normally, but the temperature of the FETs (Field Effect Transistors) started rising abnormally fast. Remedy: Allow the inverter to cool down, then press the remote’s INVERTER ON/ OFF pushbutton (manual restart) to resume operation. If the fault returns, perform an inverter reset (see Section 6.2). If the fault continues, disconnect all the inverter’s AC output wires and perform a power reset (Section 6.3).
Operation • Overcurrent – This fault may be the result of an excessive AC load and causes the inverter to shut down to protect internal power components. If the overload condition lasts for less than 10 seconds, the unit automatically restarts and resumes operation. However, if the overcurrent condition occurs for more than 10 seconds, the unit shuts down and requires a manual restart.
Operation 5.3.4.1 Stacking Fault Messages A fault condition may occur when multiple inverters are connected or stacked together. • StackClock – There is a stacker cable problem; or, one inverter is losing synchronization with the other inverter. Remedy: Ensure you are using the correct stacking cable (the cable for stacking is not a telephone/data cable, it is a custom made cable).
Operation 5.3.5 LED Indicator Guide Use the LEDs and the LCD display to determine the operating status. Table 5-1, LED Indicator Guide LED PWR (green) FAULT (red) CHG (green) INV (green) Page 55 Status Meaning 1) Inverter is disabled; 2) Remote’s in Power Save mode – press any button to activate LEDs; 3) No power to remote OFF (check remote cable or the power to the inverter); or, 4) No AC power at the inverter’s AC output terminals.
Troubleshooting 6.0 Troubleshooting The remote may not be functioning correctly, use the following table to help find a solutions. Table 6-1, Remote Control Troubleshooting Guide Symptom Possible Cause Solution Display shows unrecognizable letters or symbols Static electricity may have been discharged into the LCD display. Refresh Display: Press and hold the SELECT knob for 10 seconds.
Troubleshooting 6.1 Troubleshooting Tips 6.1.1 Inverter Problems • Inverter turned on, green LED on inverter blinking, no output: Inverter is in Search mode. Either defeat Search mode, if not needed, or turn on loads greater than the Search Watts setting. 6.1.2 Charger Problems • Unit won’t transfer to Charge mode with AC applied: Is the charge (CHG) LED on the remote blinking? If not, the charger does not recognize the incoming AC as being within acceptable limits.
Using an AGS Module: Setup 7.0 Using a ME-AGS-N Controller The AGS menus on the ME-ARC remote allow you to customize and monitor operating parameters, and to help troubleshoot your autostart/autostop generator system. IMPORTANT: The AGS must be a connected network version (ME-AGS-N) and communicating with the ME-ARC in order to set up and/or control its operation.
Using an AGS Module: Setup 7.1 Setting Up the AGS using the ME-ARC Press the SETUP button on the ME-ARC remote, and then rotate the SELECT knob to the 04 AGS Setup display. The menus available from this screen allow the generator to be automatically started and stopped based on many different conditions. From Table 7-2, determine the specific autostart and autostop conditions with which you want the generator to be automatically controlled, and then use that specific menu setting to configure the AGS.
Using an AGS Module: Setup SETUP: 04A Gen Run VDC Menu This menu provides the option to start the generator when the battery voltage gets low, and to stop the generator either when the battery reaches a higher voltage level or when the battery has been fully charged and goes into the Float charge stage. Using voltage to automatically start and stop the generator is considered the simplest and easiest method to understand.
Using an AGS Module: Setup • Set Stop Gen Volts – This setting will stop the generator when the battery voltage (on Terminals #3 & #4) increases to or above this setting continuously for the duration of the Stop Volts Delay setting. To allow the battery bank to go through a full Bulk and Absorption charge, this setting should be set to Float. Default setting: 14.4 VDC (12v), 28.8 VDC (24v), 57.6 VDC (48v) Range: OFF, 9.1-16.0 VDC (12v), 18.2-32.0 VDC (24v), 36.4-64.
Using an AGS Module: Setup SETUP: 04B Gen Run Time Menu This menu autostarts and autostops the generator based on a specific time of day. This feature uses the ME-ARC’s internal clock to start and stop the generator at the selected times. Info: Ensure the remote’s clock is correct. If needed, refer to the Section 3.2.4 for guidance on setting the time on the remote’s clock. Info: The ME-ARC clock is powered from the inverter through the remote cable.
Using an AGS Module: Setup Why would I use Gen Run Amps? This feature is designed to prevent the battery from being heavily discharged by monitoring the battery current used to power the inverter loads (shown in AC amps). When the AC current exceeds the Start Gen AC Amps setting, a generator autostart is initiated. After the generator connects to the inverter, the current from the generator is now used to run the loads instead of the battery current.
Using an AGS Module: Setup Info: The METER: 05B Battery SOC meter must have a valid SOC number for the Gen Run SOC feature to determine when to start and stop based on the battery SOC. Under the METER: 05B Battery SOC menu, Think’n, No Comm, or any BMK fault (i.e., Factory Fault, Power-up Fault, or Unknown Fault ##) are not valid SOC numbers. Info: When the Gen Run SOC feature is enabled and a generator SOC start is triggered, the remote issues a one-time “Start Bulk” command to the inverter/charger.
Using an AGS Module: Setup How does the Gen Run Temp feature work? When the temperature around the remote temperature sensor (based on the METER: 04D AGS Temp display) increases to the Gen Run Temp Start setting, the generator immediately starts and runs based on the Gen Run Temp Time setting. When this run time period is finished, the temperature sensor reading is checked.
Using an AGS Module: Setup SETUP: 04F Max Gen Run Time Menu This menu is used to set the maximum time the generator will run if autostarted. • Set Max Gen Run Time – Set this to the maximum amount of time you want the generator to run once it has been autostarted. Default setting: 12.0 Hrs Range: OFF*, 0.1-25.5 Hrs * The Max Gen Run Time setting can only be turned off using a ME-AGS-N with Ver ≥ 5.2.
Using an AGS Module: Setup • Set Quiet Time Topoff – Sets the time period the generator will autostart and run before Quiet Time starts. The generator will only start on Quiet Time Topoff if the battery voltage is within 0.3 volts¹ or less of reaching the 04A Gen Run VDC start parameter, or the battery’s SOC is within 4% or less of reaching the 04D Gen Run SOC start parameter².
Using an AGS Module: Setup SETUP: 04H Gen Exercise Menu This menu allows the generator to run (or “exercise”) after it has not been operated for a period of time. The generator is automatically started at a pre-selected time whenever it exceeds a set number of days without running. Once the start command is initiated, the generator starts and runs to help it remain operational and to allow the generator’s starting battery to be charged.
Using an AGS Module: Setup Info: When the generator starts and runs based on the gen exercise criteria, the generator power passes through the inverter to the inverter loads—if the inverter is enabled to accept AC power on its input—and also charges the inverter batteries (if the charger is enabled). Example of a Gen Exercise Scenario: Under the SETUP: 04H Gen Exercise menu: set Gen Exercise Days = 3, set Exercise Run Hour, Minute and AM-PM = 8:30A, and then set Exercise Run Time = 1.0 Hrs.
Using an AGS Module: Setup SETUP: 04K Gen 100% SOC Start Days This menu allows the AGS to autostart the generator at a pre-selected time of day and to charge the battery bank to 100% SOC—whenever a set number of days have passed since the battery bank has been charged to 100% SOC. Info: The optional Battery Monitor Kit (ME-BMK or ME-BMK-NS) must be installed and enabled to use the Gen 100% SOC Start Days feature.
Using an AGS Module: Setup Info: The Gen 100% SOC Start Days setting uses information from the BMK’s METER: 05J Days Since 100% SOC display to determine how many days have passed since the battery bank has not been charged to 100% SOC. A valid SOC number must display under the METER: 05B Battery SOC menu for the BMK’s METER: 05J Days Since 100% SOC menu to accumulate and display days. Think’n, No Comm, or any BMK fault (i.e., Internal Fault, Power-up Fault, or Unknown Fault ##) are not valid SOC numbers.
Using an AGS Module: Operation/Monitoring Info: A solid green STATUS LED means the generator has successfully started and is providing the generator run sense signal to the AGS controller. Info: If the generator attempted to start but did not run, continue to wait—the AGS will attempt to start the generator three more times. If the generator fails to start after four attempts, the STATUS LED will turn red—indicating a fault.
Using an AGS Module: Operation/Monitoring • ON – The ON selection manually starts the generator by sending a ‘start’ command from the AGS controller. Once started (by selecting “ON”), the generator must be manually stopped— either from an external stop switch or by selecting OFF from the 03 Gen Control menu (sends “stop” command from AGS). Info: When “ON” is selected, the Magnum inverter will not attempt to accept the generator AC voltage until the warm-up period is satisfied.
Using an AGS Module: Operation/Monitoring METER: 04A AGS Status Menu This read-only menu displays the AGS’s current status. There are 28 different status messages that can display to identify what state the AGS is currently in—only one displays at any one time (refer also to Figure 7-2).
