Installation 2.4.1 DC Wire Sizing It is important to use the correct sized DC wire to achieve maximum efficiency from the system and to reduce fire hazards associated with overheating. Always keep your wire runs as short as practical to prevent low voltage shutdowns and to keep the DC breaker from nuisance tripping (or open fuses) because of increased current draw. See Table 2-1 to select the minimum DC wire size (and corresponding overcurrent device) required based on your inverter model.
Installation Table 2-2, DC Wire Size For Increased Distance Inverter Model Minimum Recommended DC Wire Size (one way)* 5 feet or less 5 to 10 feet 10 to 15 feet MSH3012M #4/0 AWG (107.2 mm2) #4/0 AWG (107.2 mm2) x2 not recommended MSH4024M #2/0 AWG (67.4 mm2) #4/0 AWG (107.2 mm2) #4/0 AWG (107.2 mm2) x2 * Copper wire rated with 90°C (194°F) insulation at an ambient temperature of 30°C (86°F) in free air. 2.4.
Installation 2.4.4 Wiring the DC Overcurrent Protection Device A fuse/disconnect or circuit breaker must be provided in the DC positive line between the battery and the inverter to protect the DC wiring system. Mount the fuse block (or circuit breaker assembly) as near as practical to the batteries. For maximum protection, install it within 18 inches (45 cm) of the battery. 1.
Installation 2.4.6 Battery Temperature Sensor Installation and Wiring The Battery Temperature Sensor (shown in Figure 2-7) provides the inverter with precise battery temperature information to automatically adjust the charge voltage set-points (Absorb, Float or Constant Voltage). This allows the batteries to be correctly charged under extreme temperature changes. If the temperature sensor is NOT installed and the batteries are subjected to large temperature changes, the battery life may be shortened.
Installation 2.4.7 Wiring the Inverter to the Battery Bank CAUTION: The inverter is NOT reverse polarity protected—if this happens the inverter will be damaged and will not be covered under warranty. Before connecting the DC wires from the batteries to the inverter, verify the correct battery voltage and polarity using a voltmeter. If the positive terminal of the battery is connected to the negative terminal of the inverter and vice versa, severe damage will result.
Installation 2.5 AC Wiring This section provides information on how to make the AC connections to the inverter using the correct AC wire size and corresponding overcurrent protection. 2.5.1 Pre-AC Wiring Requirements CAUTION: Before installing any AC wiring, review the safety information at the beginning of this manual and the following to ensure a safe and long-lived system: • Always use properly rated circuit breakers.
Installation 2.5.3 Recommended GFCI (Ground Fault Circuit Interruption) Outlets Some electrical safety codes require the use of GFCI’s. In compliance with UL standards, Magnum Energy has tested the following GFCI’s and find that they function properly when connected to the inverter’s AC output: • Shock SentryTM #XGF15V-SP • Leviton Smart Lock #8899-A • Hubbel #GF520EMBKA CAUTION: GFCIs shall be installed in a recreational vehicle’s wiring system to protect all branch circuits. 2.5.
Installation 2.5.5 AC Conductor Wiring The following steps are basic guidelines for installing and connecting AC wiring to and from an MSH-M Series inverter. WARNING: Before making any AC connections, make sure the inverter is disconnected from the battery and no AC power is connected to the inverter. Remove the two Phillips screws on the AC wiring access cover (Item 15, Figure 1-3) to access the internal AC terminal block (see Figure 2-8). Wiring the Inverter AC Input 1.

ON ON OFF ON OFF ON OFF OFF ON ON OFF ON OFF OFF ON OFF A maximum 60-amp single-pole breaker is required on the inverter’s AC input.
Installation 2.6 Grounding Inverters The MSH-M Series inverter/charger uses both AC and DC electrical systems, therefore each electrical system is required to be properly connected to a permanent, common “ground” reference. An inverter that is properly grounded limits the risk of electrical shock, reduces radio frequency noise, and minimizes excessive surge voltages induced by lightning.
Installation 2.6.1 Equipment Grounding Conductors The inverter case and all other noncurrent-carrying exposed metal surfaces in the entire electrical system—that may be accidentally energized—must be grounded. The equipment-grounding conductor must be sized to safely carry the maximum ground-fault current likely to be imposed on it from where a ground-fault may occur.
Installation 2.6.4 Grounding on Boats When installing the MSH-M Series inverter/charger on a boat, there are several considerations that must be followed when grounding to ensure a safe installation, prevent galvanic corrosion, and to adhere to ABYC (American Boat and Yacht Council) standards. Ensure a Safe Ground Connection When AC on the boat is being supplied by shorepower, the onboard neutral should be connected to safety ground on the dock.
Installation 2.6.5 Neutral to Safety Ground Bonding The standards for safely wiring RV, truck, and marine installations in the United States require the neutral and safety ground to be connected at the AC source; whether it is a shorepower feed, an inverter, or a generator. This is to establish a specification that maximizes the possibility that a circuit breaker will activate if a hotwire-to-ground fault occurs.
Installation 2.6.6 Connecting a Large DC Ground Wire Some marine installations require the DC ground wire to be the same size or one size smaller than the negative cable. Use the following steps to allow a larger ground wire to be connected. 1. Locate the DC ground terminal (Item 7, in Figure 1-2). 2. Locate and remove the AC access cover plate (Item 15, in Figure 1-3) on the side of the inverter. 3. Within the AC wiring area, locate the hex nut on the back side of the DC ground terminal.
Installation 2.9 Functional Test After all electrical connections to the inverter, batteries, AC source and sub-panel have been completed, follow these steps to test the installation and the inverter’s operation. CAUTION: Use a multimeter to verify the correct DC voltage for your particular inverter model (i.e.
Operation 3.0 Operation The MSH-M Series inverter has two normal operating routines: Inverter mode, which powers your loads using the batteries, and Standby mode, which transfers the incoming AC current (i.e., shorepower power or a generator) to power your loads and to recharge the batteries. This inverter also includes an extensive protection circuitry to shut down the inverter under certain fault conditions. 3.1 Inverter Mode When the MSH-M Series is first powered up, it defaults to the OFF mode.
Operation 3.2 Standby Mode The MSH-M Series features an internal battery charger and an automatic transfer relay when operating in Standby mode. The Standby mode begins whenever AC power (shorepower or generator) is connected to the inverter’s AC input. Once the AC voltage and frequency of the incoming AC power is within the AC input limits, the AC transfer relay activates. This transfer relay passes the incoming AC power through the inverter to power the AC loads on the inverter’s output.
Operation The Charge mode provides up to four separate charging stages: Bulk Charging, Absorb Charging, Float Charging and Full Charge. Bulk Charging: This is the initial stage of charging. While bulk charging, the charger supplies the battery with controlled constant current. The charger will remain in bulk charge until the absorption charge voltage (determined by the Battery Type selection*) is achieved. The inverter’s green LED stays ON (solid) to indicate bulk charging.
Operation 3.2.2 Load Support While in the Standby Mode and the charger is enabled, the MSH-M Series inverter/charger has the ability to work in parallel with the incoming AC source to support the AC loads using current from the batteries. During the Standby mode, the current and voltage from the AC source and the AC load current are continually monitored.
Operation 3.3 Current Flow The following figures show the current flow in the MSH-M Series during different modes: Inverting – The MSH inverter converts the current from the battery to power the AC loads. MSH Inverter DC Current (Battery) AC Current (Grid/Gen) 0A -10A AC Loads (Small) +10A Figure 3-4, MSH Current Flow – Inverting Charging and AC Pass-thru – The MSH inverter uses current from the grid/generator to power the AC loads, and also converts this current to charge the battery.
Operation Load Support AAC – If AC loads are added that are above the capability of the grid/generator, the MSH converts current from the battery and combines it with the current from the grid/ generator to power the additional AC loads. DC Current (Battery) MSH Inverter AC Current (Grid/Gen) -20A -10A AC Loads (Large) +30A Figure 3-7, MSH Current Flow – Load Support AAC Load Support VDC – If the battery is being charged externally (i.e.
Operation 3.5 Battery Temperature Sensor Operation The plug-in Battery Temperature Sensor (BTS) is used to determine the battery’s temperature. This information allows the multi-stage battery charger to automatically adjust the battery charge voltages for optimum charging performance and longer battery life.
Operation 3.6 Protection Circuitry Operation The inverter is protected against fault conditions and in normal usage it will be rare to see any. However, if a condition occurs that is outside the inverter’s normal operating parameters, it will shut down and attempt to protect itself, the battery bank, and your AC loads. If there is a condition that causes the inverter to shut down, it may be one of the following conditions [also refer to the Troubleshooting section (Section 4.
Operation 3.7 Inverter Startup ON/OFF Switch – The inverter can be turned on and off by lightly pressing and releasing the Power ON/OFF switch on the front of the inverter (refer to Figure 3-10). When the inverter is first connected to the batteries, or when its automatic protection circuit has turned the inverter off, the ON/OFF switch will need to be pressed to start the unit (or reset per Section 4.4).
Operation 3.8 Factory Default Values Your MSH-M Series inverter/charger uses default values for the adjustable settings (shown in Table 3-2) that are adequate for most installations. If some of your operating parameters need to be changed from the default values, an optional remote control/display can be used to make those changes. To help you determine if you need a remote display, information on the inverter/charger settings that can be changed is provided below.
Operation 3.9 Inverter Fan Operation The inverter contains two internal cooling fans that are automatically controlled. The speed of these fans is determined either by the internal temperature of the inverter or by the load on the inverter. The inverter’s fans will come on under the conditions listed below: • Fans run full speed if the internal transistors (FETS) or the power transformer reaches 80°C (176°F), or the inverter is running at 100% of its rated load.
