Battery symbol on the home screen is yellow
• The battery is low, or the charge/discharge current is close to the programmed limit (which is ok)
Grid symbol on the home screen is yellow
• Grid parameters are out of specified range or grid is down
System has restarted
• It happens if the system is overloaded, battery voltage is greater than 63V, or Software update
Batteries were connected backward
• The battery breaker will trip. It can cause damage!
Why is the LCD screen still on when the power button is off?
• If PV or Grid power, LCD stays on, but the inverter and loads are off.

• Click the battery icon on the front of the inverter and look to see what the AC Output voltage is:
• If the AC Output Voltage is ~100V per leg (N/A in 220V single-phase grid mode), then check whether you are
missing a neutral connection, have a loose neutral wire, or have a damaged neutral wire somewhere in your AC
wiring.
• If the AC Output Voltage is ~120V per leg (N/A in 220V single-phase grid mode) and you have more than one
inverter in parallel, contact engineering support for further assistance.
