Introduction 1.0 Introduction The ME Series is a modified sine wave inverter designed especially for mobile applications. Powerful, yet simple to operate, this inverter/charger will provide you with the years of troublefree performance—backed by our limited 3-year warranty. Installation is easy. Simply connect the inverter’s output to your distribution circuits or electrical panel, connect your AC to the inverter’s easy-to-reach terminal block, connect the batteries, and then switch it on for power.
Introduction 1.2 What Appliances will run from a Modified Sine Wave Inverter Today’s inverters come in two basic output waveforms: modified sine wave (a modified square wave—see Figure 1-5) and pure sine wave. Modified sine wave inverters approximate a pure sine waveform and will run most appliances and electronics without any problems. These inverters are less expensive, and therefore, offer a viable alternative to more expensive pure sine inverters.
Introduction 7 DC Equipment Ground Terminal – this connection is used to tie the exposed chassis of the inverter to the DC grounding system. This terminal accepts CU/AL conductors from #14 to #2 AWG (2.1 to 33.6 mm2). 8 AC Input/Output Connections – two 3/4” knockouts provided with cable-clamp strain reliefs to allow and hold the AC input and output field wiring. 9 Intake Air Vents – ventilation openings to pull in air to help keep the inverter cool for peak performance.
Introduction The left side of the ME Series is equipped with the following features (see Figures 1-3 and 1-4): 13 Exhaust Air Vents – ventilation openings that allow heated air to be removed by the internal cooling fan. 14 Model/Serial Number Label – includes model/serial number information, date of manufacture, and inverter and charger specifications.

Installation 2.6 Grounding Inverters The inverter/charger should always be connected to a permanent, grounded wiring system. An inverter system that is properly grounded will limit the risk of electrical shock, reduce radio frequency noise from the inverter, and minimize excessive surge voltages induced by lightning. This is done by ensuring there is a well-defined, very low-resistance path from the electrical system to the grounding system.
Installation 2.6.2 Grounding on Boats When installing the ME 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 adhere to American Boat and Yacht Council (ABYC) standards. Ensure a Safe Ground Connection When AC on the boat is being supplied by shorepower (also referred to as “utility power”), the onboard neutral should be connected to safety ground on the dock.
Installation 2.6.3 Neutral to Safety Ground Bonding The recommended standards for safely wiring mobile and marine installations require that the neutral and safety ground be connected at the AC source; whether it is an inverter, utility power, or a generator. This is to establish a specification that maximizes the possibility that a circuit breaker will activate if a hot-wire-to-ground fault occurs.
Installation 2.6.4 Connecting a Large DC Ground Wire 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. WARNING: Fire and Shock Hazard – disconnect all AC and DC sources before working in the AC wiring compartment. 1. Remove the inverter’s AC access cover plate (see Figure 1-3, Item 15). 2. Locate the DC Equipment Ground Terminal (see Figure 1-2, Item 7). 3.
Installation 2.8 Final Inspection 1. Verify all cable runs are secured with wire ties or other non-conductive fasteners to prevent chafing, or damage from movement and vibration. 2. Verify strain reliefs or grommets are in place to prevent damage to the wiring where it passes through walls, bulkheads, or other openings. 3. Verify all AC connections are correct and torqued to a maximum of 16 lbf-in (1.8 N-m). 4. Replace the covers on the main electrical/distribution panel. 5.

Operation 3.0 Operation The ME Series inverter has two normal operating routines: Inverter mode, which powers your loads using the batteries; and Standby mode, which transfers the incoming AC power (e.g., utility 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 ME Series is first powered up, it defaults to the OFF mode.
Operation 3.2 Standby Mode The ME Series features an automatic transfer relay and an internal battery charger when operating in Standby mode. Standby mode begins whenever AC power (utility 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, an automatic AC transfer relay is activated. 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 (see Figure 3-3). Bulk Charging: This is the initial stage of charging. While bulk charging, the charger supplies the battery with 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 3.4 Transfer Time While in Standby mode, the AC input is continually monitored. Whenever AC power falls below the VAC dropout voltage (80 VAC, default setting), the inverter automatically transfers back to Inverter mode with minimum interruption to your appliances—as long as the inverter is turned on. The transfer from Standby mode to Inverter mode occurs in approximately 16 milliseconds.
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 Power ON/OFF Switch – The inverter can be turned on/off by lightly pressing and releasing the Power ON/OFF switch on the front (see Figure 3-5). 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). Once the inverter has been turned on, pressing the Power ON/OFF switch alternately turns the inverter on and off.
Operation 3.8 Factory Default Values The ME Series inverter/charger uses default values for the adjustable settings (Table 3-2) that are adequate for most installations. If 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 the 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 degrees Celsius (176°F), or the inverter is running at 100% of its rated load.
Maintenance and Troubleshooting 4.0 Maintenance and Troubleshooting The following information is provided to help you keep your ME Series inverter/charger in optimum operational condition. 4.1 Recommended Inverter and Battery Care The ME Series inverter/charger is designed to provide you with years of trouble-free service.
Maintenance and Troubleshooting Symptom Possible Cause Recommended Solution No output power. Inverter LED is OFF. (Cont.) Battery voltage is too high. The inverter automatically resets and resumes operation when the battery voltage drops to the HBCI voltage or lower. Condition usually only occurs when an additional charging source (external charging sources) is used to charge the battery bank. Reduce/turn off any other charger to the inverter batteries to allow voltage level to drop.
Maintenance and Troubleshooting 4.4 Resetting the Inverter Under some fault conditions (e.g., an internal fault), the inverter will need to be reset. Prior to performing any reset, ensure all AC power (utility, generator, shorepower) is removed from the inverter’s input. CAUTION: If AC is connected while performing an inverter reset, damage may occur. 4.4.1 Performing an Inverter Reset To perform an inverter reset (also known as a “soft reset”): 1.
