EG4® 6000XP Monitor System Working Modes

This guide will assist the user in configuring and customizing the integrated working modes of the 6000XP off-grid inverter.

1. Operating Mode Description

The EG4 6000XP inverter offers several preset working modes for extensive system customization. This guide helps users set the station's needs based on factors like time of day.

Working Mode Definitions:

Off-Grid Mode: The system operates on a pre-set priority. The inverter draws power from solar arrays for loads. If solar power is insufficient, it draws from the battery bank. As a last resort, it switches to bypass mode to power loads from AC input.
Bypass Mode: Grid power handles the load demand, while solar energy charges the battery.
Power Backup Mode: The battery discharges its stored energy only during a grid power outage.
AC Charge Mode: During AC charge time, if solar power is insufficient, grid power supplements battery charging.

2. Off-Grid Mode

Source Priority: Solar > Battery > Utility Grid (SBU)

If solar power exceeds the load, solar powers the load first, and excess solar charges the battery. If solar power is less than the load, solar and battery power the load together. The system discharges the battery until it reaches the EOD Voltage/SOC.
