Page 39: Grounding Inverters
The ME Series inverter/charger uses both AC and DC power; however, the AC electrical system is isolated from the DC electrical system by an internal transformer. Although this inverter/charger has two electrical systems, each must be properly grounded and connected to a common point. - Page 40 (see Figure 2-18). The DC ground terminal on the ME Series must also be connected to the boat’s safety ground bus. This ensures that both the inverter’s AC and DC ground terminals are connected to the boat’s safety ground bus as a safety measure to provide protection against faults, and to provide a path for AC fault currents while the boat is connected to shore power.
-

AC source (e.g., shore power or a generator) is qualifi ed, another neutral-to-ground connection is introduced in the system. When the ME Series is connected to this external AC source and goes into Standby Mode, the internal relay automatically opens the neutral-to-ground connection, as shown in Figure 2-19. -

Page 46: 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 (shore power 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 47: Figure 3-3, Automatic 4-Stage Charging Graph
Info: If the battery voltage falls to the re-bulk voltage (12.1 VDC) or lower, the unit will begin another bulk charge. * These settings in the ME Series are changeable and leave the factory with default values (see Table 3-2, Inverter/Charger Default Values). These default values are adequate for most installations, however, if you determine that some of the values need to be changed for your particular system, the ME-RC50 remote control may be purchased to adjust these settings. -
Page 48: Transfer Time
The transfer from Standby Mode to Inverter Mode occurs in approximately 16 milliseconds. While the ME Series is not designed as a computer UPS system, this transfer time is usually fast enough to hold them up. However, the VAC dropout setting has an effect on the ability of the loads to transfer without resetting. -

Questions and answers
Unit is not sending battery AC power to interior circuits.
The Magnum Energy ME Series unit may not be sending battery AC power to interior circuits because it is in standby mode, where it monitors for acceptable AC voltage from an external source before activating the AC transfer relay. If no AC source is connected or the voltage is not acceptable, the relay remains open, preventing power transfer. Additionally, issues such as a tripped AC input circuit breaker, incorrect wiring, or battery-related problems could also cause this issue.
