What to do if my PowMr POW-SunSmart 8KE shows 'Bypass over-load (software detection)'?
If your PowMr Inverter displays a 'Bypass over-load (software detection)' error, it means the bypass output power or current has been too high for too long. To resolve this, reduce the power being drawn by your connected devices and then restart the inverter. For further details, consult protection feature item 11.
What to do if PowMr Inverter says 'Battery not connected'?
If your PowMr Inverter indicates 'Battery not connected', verify the battery is properly connected. Also, check that the battery's circuit breaker is closed and that the BMS of the Li-ion battery can communicate correctly.
Why does my PowMr Inverter show 'Battery over-voltage when charging'?
If your PowMr Inverter shows a 'Battery over-voltage when charging' error, the battery voltage is too high. You should manually power off and restart the inverter. Check if the battery voltage exceeds the limit. If it does, discharge the battery until its voltage is below the over-voltage recovery point.
What to do if PowMr POW-SunSmart 8KE indicates 'Battery over-discharge'?
If your PowMr Inverter displays a 'Battery over-discharge' error, it signifies that 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 the battery voltage exceeds the value set in parameter [35].
Why does my PowMr POW-SunSmart 8KE Inverter show 'Battery under-voltage'?
If your PowMr Inverter shows a 'Battery under-voltage' error, the battery voltage is lower than the value set in parameter [14]. Charge the battery until its voltage is higher than the value set in that parameter.
What causes 'Utility input phase fault' on my PowMr POW-SunSmart 8KE Inverter?
If your PowMr Inverter displays 'Utility input phase fault', it means the AC input phase doesn't match the AC output phase. Make sure the AC input phase is the same as the AC output phase. For example, if the output is in split-phase mode, the input must also be in split-phase.
How to fix a PowMr Inverter with 'Screen no display'?
If your PowMr Inverter screen is not displaying anything, it could be due to no power input or the device being in sleep mode. Ensure the circuit breaker is closed and the rocker switch is ON. If it's in sleep mode, push any button on the panel to wake it up.
What should I do if my PowMr POW-SunSmart 8KE Inverter reports a 'Fan failure'?
If your PowMr Inverter reports a 'Fan failure', the hardware has detected a fan issue for 3 seconds. Try manually toggling the fan after switching off the device to check if it's blocked by any foreign objects.
What does 'AC Input relay short-circuit' mean on my PowMr POW-SunSmart 8KE?
If your PowMr Inverter indicates an 'AC Input relay short-circuit', it suggests the relay for AC input is sticking. Manually power off and restart the device. If the fault persists after restarting, contact after-sales service for repair.
