Why does my Srne HF4850U80-H say PV overvoltage?
This occurs when the PV input voltage exceeds the maximum allowable input voltage. Use a multimeter to check if the PV input voltage is within the acceptable range.
What to do if my Srne HF4850U80-H Battery Charger shows charge battery overvoltage protection?
The charge battery overvoltage protection is triggered when the battery voltage exceeds 60V. You should measure the battery voltage to verify if it exceeds 60V. If it does, disconnect the photovoltaic array air switch and the AC air switch.
What to do if Srne Battery Charger has bypass overload protection or inverting overload protection?
To resolve bypass or inverting overload protection issues, try decreasing the consumer load. After doing so, restart the all-in-one machine. The load output should then be restored.
How to fix Srne Battery Charger inverting short-circuit protection?
To fix an inverting short-circuit protection fault, carefully check the load connection condition and clear the short-circuit fault point. After resolving the short circuit, power the device on again to restore the load output.
What to do if my Srne HF4850U80-H has no connection alarm of battery?
The 'no connection alarm of battery' indicates that the battery is disconnected or the breaker at the battery side is not closed. Check to ensure the battery is properly connected and the breaker is closed.
What to do if the Srne HF4850U80-H screen is blank?
If there is no display on the screen, verify that the battery air switch or PV air switch is closed and that the switch is in the "on" state. You can also try pressing any key on the screen to exit from the screen sleep mode.
What to do if my Srne Battery Charger fan is not working?
Check if the fan isn't working or if it's blocked by something.
