What to do if my PowMr POW-SunSmart 8KP has no screen display?
If your PowMr Inverter screen is blank, it may not be receiving power or the device switch at the bottom isn't on. First, check if the battery or PV air-switch is closed. Then, make sure the switch is in the 'ON' position. Finally, press any button on the screen to wake it from sleep mode.
What to do if PowMr POW-SunSmart 8KP Inverter shows a 'Disconnected battery' error?
If your PowMr Inverter indicates a disconnected battery, the battery might not be properly connected, or the lithium-ion battery's BMS is in discharge protection. Check the battery connection to ensure it's secure. Also, verify that the battery's circuit breaker is closed and confirm that the Li-ion battery's BMS can communicate correctly.
Why does my PowMr POW-SunSmart 8KP Inverter show 'Battery under- voltage'?
The 'Battery under- voltage' error on your PowMr Inverter means the battery voltage is lower than the set value in parameter [14]. To resolve this, charge the battery until its voltage exceeds the value specified in parameter [14].
What to do if PowMr POW-SunSmart 8KP displays 'Battery over- discharge'?
If your PowMr Inverter shows 'Battery over- discharge', the battery voltage is lower than the value set in parameter [12]. You can manually reset it by powering off and restarting the device. Alternatively, it will automatically reset once you charge the battery so that its voltage is higher than the value set in parameter [35].
What causes 'Battery over- voltage when charging' on PowMr POW-SunSmart 8KP?
The 'Battery over- voltage when charging' error on your PowMr Inverter indicates that the battery voltage is too high. Power off and restart the inverter manually. Check if the battery voltage exceeds the limit. If it does, discharge the battery until the voltage drops below the battery's over-voltage recovery point.
What to do if my PowMr Inverter shows 'Bypass over- load (software detection)'?
The 'Bypass over- load (software detection)' error on your PowMr Inverter indicates that the bypass output power or current has been overloaded for too long. Reduce the load power and then restart the device. For more details, refer to item 11 of the protection features.
What to do if my PowMr POW-SunSmart 8KP shows 'Utility input phase fault'?
The 'Utility input phase fault' on your PowMr Inverter means the AC input phase doesn't match the AC output phase. Ensure that the phase of the AC input is the same as the phase of the AC output. For example, if the output is in split-phase mode, the input must also be in split-phase.
What causes 'Heat sink of PV input over- temperature (software detection)' in PowMr POW-SunSmart 8KP Inverter?
The 'Heat sink of PV input over- temperature (software detection)' error on your PowMr Inverter means the PV input heat sink temperature has exceeded 90 degrees Celsius for 3 seconds. The device will resume normal charge and discharge when the heat sink temperature cools down to below the over-temperature recovery temperature.
How to fix a PowMr POW-SunSmart 8KP Inverter with a fan failure?
If your PowMr Inverter reports a fan failure, which is detected by hardware for 3 seconds, switch off the inverter and manually toggle the fan to check if any foreign objects are blocking it.
What to do for 'AC Input relay short- circuit' in PowMr POW-SunSmart 8KP Inverter?
If your PowMr Inverter displays an 'AC Input relay short- circuit' error, it indicates that the relay for the AC input is sticking. Try manually powering off and restarting the device. If the fault reappears after restarting, you need to contact after-sales service to repair the machine.
