Problems During Operation
The inverter does not start up with battery only
Solution:
Make sure that the battery voltage is greater than 48V. Otherwise, the battery cannot start the
inverter.
The inverter did not start up with PV only
Solution:
1. Make sure the PV voltage is greater than 125V.
2. Make sure that, for the connection between the inverter and PV panels, the polarities are (+/-)
not reversed.
The hybrid inverter does not discharge or output without the PV or when the PV power is
less than the load power
Solution:
1. Check whether the communications between the inverter and Smart Meter are OK.
2. Make sure the load power is greater than 150W.
a. The battery will not discharge continuously unless the load power is greater than 150W.
b. If the battery does not discharge when the Meter power is greater than 150W, please check
the Smart Meter & CT connections and directions.
3. Make sure the SOC (State of discharge) is greater than 1-DOD (Depth of discharge). Or, if
the battery is discharged to below 1-DOD, the battery will only discharge again when SOC is
charged to (20%+1-DOD/2 (if battery discharge is needed immediately, the user should restart
the battery).
4. Check on the APP whether the charge time has already been set because during the charge
time, the battery will not discharge (battery will charge in priority during times of concurrent
charge/discharge).
The battery does not charge when the PV power is greater than the load power
Solution:
1. Check if charge voltage on App(in "param")is properly set(for lead-acid battery), as battery
cannot charge if battery voltage reaches charge voltage.
2. Check the discharge time setting on App.
3. Check if battery is fully charged or not, or if battery voltage reaches "charge voltage" or not.
