How to fix Srne ASF48120SH3 with no screen display?
If your Srne Inverter shows no screen display, first ensure that the battery or PV air circuit-breakers are turned on. Then, check if the power switch located on the bottom of the unit is in the "ON" position. Finally, press any button on the screen to ensure it is not in sleep mode.
Why is my Srne Inverter showing battery under-voltage?
If your Srne Inverter indicates a battery under-voltage, it means the battery voltage is lower than the value set in parameter [14]. To resolve this, charge the battery and wait until its voltage exceeds the value specified in parameter [14].
What to do if Srne Inverter says battery not connected?
If your Srne Inverter is showing a 'Battery not connected' error, this could be due to a loose connection or the BMS being in discharge protection state. Check that the battery is reliably connected and that the battery circuit-breaker is not off. Also, make sure that the BMS can communicate properly.
Why is my Srne Inverter showing battery over-voltage when charging?
If your Srne Inverter displays a battery over-voltage error during charging, it means 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 the voltage drops below the battery over-voltage recovery point.
What to do if Srne ASF48120SH3 shows bypass overload error?
If your Srne Inverter indicates a bypass overload (software detection), it means the bypass output power or current has exceeded the limit for some time. Reduce the load power connected to the inverter and then restart the device. More details can be found in item 11 of the protection function description.
How to fix Srne ASF48120SH3 battery over-discharge error?
If your Srne Inverter is showing a battery over-discharge, it means that the battery voltage is lower than the value set in parameter [12]. You can manually reset the inverter by switching it off and then restarting it. Alternatively, the inverter will automatically reset once you charge the battery so that its voltage is higher than the value set in parameter item [35].
Why does my Srne ASF48120SH3 show a utility input phase fault?
If your Srne Inverter reports a utility input phase fault, it indicates that the AC input phase does not 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 mode.
What does fan failure mean on Srne ASF48120SH3?
If your Srne Inverter reports a fan failure, it means the hardware has detected a problem with the fan. After powering off the machine, manually toggle the fan to check for any blockage caused by foreign matter.
What to do if Srne ASF48120SH3 shows AC input relay short-circuit?
If your Srne Inverter displays an AC input relay short-circuit error, it indicates that the relay for the AC input is sticking. Manually turn off and restart the machine. If the fault reappears after restarting, contact after-sales service to repair the machine.
