solution
If the alarm occurs occasionally, the possible cause
is that the electric grid is abnormal occasionally.
ME3000SP automatically returns to normal
operating status when the electric grid's back to
normal.
If the alarm occurs frequently, check whether the
grid voltage/frequency is within the acceptable
range. If no, contact technical support. If yes, check
the AC circuit breaker and AC wiring of the
ME3000SP.
If the grid voltage/frequency is within the
acceptable range and AC wiring is correct, while the
alarm occurs repeatedly, contact technical support
to change the grid over‐voltage, under‐voltage,
over‐frequency, under‐frequency protection points
after obtaining approval from the local electrical
grid operator.
If the alarm occurs occasionally, the possible cause
is during the process of charging.
If the alarm occurs occasionally, check whether the
overvoltage setting of the battery consistent with
the parameter of battery manufacturer and contact
technical support.
ID09‐ ID26 are internal faults of ME3000SP, turn OFF
the "DC & AC switch", wait for 5 minutes, then turn
ON the "DC switch" and turn ON the "AC switch".
Check whether the fault is rectified. If no, please
contact technical support.

Questions and answers
I have no display information on the inverter, just a blank screen
The Mass Energy ME 3000SP inverter may not display information due to the following reasons:
1. Power Supply Issue – The inverter may not be turned on, or the DC & AC breakers may be off. Ensure the inverter is powered.
2. Connection Issue – If the CT connection has been changed, the setup procedure must be repeated.
3. Firmware Update Issue – If a firmware update fails, the inverter may not function properly. Ensure the update completes successfully and restart the inverter.
4. Screen Failure – If the LCD screen does not turn on after power is supplied, there might be a hardware malfunction.
Check power connections, restart the inverter, and verify successful firmware updates to resolve the issue.
