EG4 12000XP - Off-Grid; First Time Power up

22
Generator Start Conditions:
The generator will start when the utility fails and one of the following conditions is met:
• The battery is discharged to the cut-off setting or
• There is a force charge request from battery or
• The battery voltage or SOC is lower than the “Generator Charge Start Battery Voltage(V) or
SOC(%).
Generator Stop Conditions:
When battery voltage or SOC is higher than the “Generator Charge End Battery Voltage(V)/SOC(%)”
settings.
7.6 OFF-GRID
The EG4
®
12000XP inverter can fully function in off-grid mode. It does not need the utility or
generator to function. Purely off-grid systems that do not have access to the utility should strongly
consider having a 2-wire start backup generator for extended cloudy periods (6kW – 15kW per
12000XP). Off-grid systems should have adequately sized battery banks to ensure multiple days of
power and to reduce generator run time.
The 12000XP can accept up to 63A (6kW – 15kW) of generator power and will pass through all
available power to the loads. Therefore, the loads subpanel can be sized up to the size of the
backup generator with 63A minimum per inverter.
8. FIRST TIME POWER UP
This section describes powering on a single or multiple inverters for the first time, including the related
configurable settings on the LCD screen. These settings can also be configured using the mobile app
or Monitor Center website after a user account is created. Follow the steps in section 11.2 to create a
new user account and then section 12 for using Monitor Center.
WARNING:
If more than one inverter is installed and interconnected as one energy storage
system, follow section 7.2. Each inverter must be properly configured to work
together in parallel mode before outputting current on the load ports. If the
proper configuration is not followed, damage could be caused to the inverter
and the connected devices.
