This is done by ensuring there is a well-defi... -
Page 36: Grounding On Boats
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. -
Page 37: Neutral To Safety Ground Bonding
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 specifi cation that maximizes the possibility that a circuit breaker will activate if a hot-wire-to-ground fault occurs. -

Page 39: Functional Test
Installation 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 operation. CAUTION: Use a multimeter to verify the correct DC voltage for your particular inverter model (i.e., 12-volt battery bank for a 12-volt inverter), and to ensure the polarity of the battery voltage is correct (battery positive connected to the inverter positive terminal and battery negative connected to the inverter negative terminal). -
Page 40: 3.0 Operation
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. -
Page 41: Standby Mode
Operation 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. -
Page 42: Figure 3-3, Automatic 4-Stage Charging Graph
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. -
Page 43: Transfer Time
Operation 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. -
Page 44: Protection Circuitry Operation
Operation 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 4.3) to help diagnose and clear the fault condition]: •... -
Page 45: Inverter Startup
Operation 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 fi rst 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). -
Page 46: Factory Default Values
Operation 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. -
Page 47: Inverter Fan Operation
Operation 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: •... -
Page 48: 4.0 Maintenance And Troubleshooting
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. Recommended Inverter and Battery Care The ME Series inverter/charger is designed to provide you with years of trouble-free service. Even though there are no user-serviceable parts, it is recommended that every 6 months you perform the following maintenance steps to ensure optimum performance and extend the life of your batteries. - Page 49 Maintenance and Troubleshooting Symptom Possible Cause Recommended Solution No output power. Battery voltage is too high. The Condition usually only occurs when an Inverter LED is inverter automatically resets and additional charging source (external charging OFF. (Cont.) resumes operation when the battery sources) is used to charge the battery bank.

Page 50: Resetting The Inverter
Maintenance and Troubleshooting 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”):... -
