Solution
1. Try to lower the ambient temperature.
2. Make sure that the inverter is installed according
to the manual and there is no shelter around the
inverter.
3. After the inverter is powered off and waiting for
30 minutes, then restart it. If the fault still exists,
please call the service center.
The effective value of grid voltage exceeds the
maximum protection value of national standard
voltage.
1. Whether the off grid output terminal is short
circuited or has impact load.
2. Restart the inverter to see if the fault still exists.
If it still exists, please call the service center.
Restart the inverter to see if the fault still exists. If
it still exists, please call the service center.
1. Check whether the off grid output terminal is
overloaded, short circuited or has impact load.
2. Restart the inverter to see if the fault still exists.
If it still exists, please call the service center.
Restart the inverter to see if the fault still exists. If it
still exists, please call the service center.
1. Use a multimeter to test the impedance of the off
grid output. If it is small, check whether the wiring
is correct.
2. Restart the inverter to see if the fault still exists.
If it still exists, please call the service center.
1. Check whether the load exceeds the rated power.
2. Restart the inverter to see if the fault still exists. If
it still exists, please call the service center.
Check that the actual battery voltage is 10V higher
than the battery charging cut-off voltage
Check that the actual battery voltage is 10V higher
than the battery discharging cut-off voltage
Check whether the load exceeds 0.95 of the rated
power
Restart the inverter to see if the fault still exists. If
it still exists, please call the service center.
1. Check whether the total power of the battery
and PV is less than the load power.
2. Restart the inverter to see if the fault still exists.
If it still exists, please call the service center.
