3. If the error message persists, please contact
Growatt support.
The BMS reports that the
battery failed to
charge/discharge
1. Figure out the fault based on the BMS error
code.
2. If the error message persists, please contact
Growatt support.
The battery voltage is
below the lower threshold
1. Check the battery voltage.
2. If the error message persists, please contact
Growatt support.
The battery voltage
exceeds upper threshold
1. Check the battery voltage. If it is within the
permissible range, please restart the inverter. If
not, please replace the battery.
2. If the error message persists, please contact
Growatt support.
The battery temperature
is beyond the range for
charging/discharging
1. Check the temperature of the battery.
2. If the error message persists, please contact
Growatt support.
Battery terminals
reversed
1. Check if the battery terminals are reversely
connected.
2. If the error message persists, please contact
Growatt support.
1. Check the wiring of the battery terminals.
2. If the error message persists, please contact
Growatt support.
Battery overload
protection
1. Check if the power of the load exceeds the
battery rated discharge power.
2. If the error message persists, please contact
Growatt support.
1. Restart the inverter.
2. If the error message persists, please contact
Growatt support.
BAT Charge OCP
(Overcurrent Protection)
1. Check if the PV voltage is oversized.
2. If the error message persists, please contact
Growatt support.
BAT Discharge OCP
(Overcurrent Protection)
1. Check if the battery discharge current
configuration is proper.
2. If the error message persists, please contact
Growatt support.
1. Restart the inverter.
2. If the error message persists, please contact
Growatt support.
Off-grid output
short-circuited
1. Restart the inverter.
2. If the error message persists, please contact
Growatt support.
