Trouble shooting
Restart inverter, if the error still exist, contact us (DSP&M3)
Restart inverter, if the error still exist, contact us (DSP&M3)
Restart inverter, if the error still exist, contact us (DSP&M3)
Check CAN cable connection is connected to the right
COM port
Check parallel setting for master/Slave part,
there should be one master in the system
Check parallel setting for master/Slave part,
there should be one master in the system
Check if AC Connection is same for all inverters in
parallel system
Check if the load is short circuit, try to turn off the load
and restart inverter
Restart inverter, if the error still exist, contact us
Check if the AC connection is right for three phase system,
there should one at least one inverter in each phase
Restart inverter, if the error still exist, contact us
Restart inverter, if the error still exist, contact us (DSP&M8)
Restart inverter, if the error still exist, contact us (DSP&M3)
Check if PV input voltage is higher than 480V
Check if EPS and AC connection is in wrong terminal
Check PV input connection and if PV input voltage is
higher than 480V
Restart inverter, if the error still exist, contact us
Check PV connection
The internal temperature of inverter is too high,
turn off the inverter for 10minutes, restart the inverter,
if the error still exist, contact us
Restart inverter, if the error still exist, contact us (Bus sample)
Restart inverter, if the error still exist, contact us (DSP&M8)

Trouble shooting
Check if you have choose the right battery brand and
communication cable is right, if the warning still exist,
contact us
Check battery temperature sensor is right connected
and the battery temperature is not too high
Check battery temperature sensor is right connected
and the battery temperature is not too low
Inverter get battery fault info from battery BMS,
restart battery, if the warning still exist,
contact us or battery manufacture
Please contact Luxpower for firmware update
Check if the fan is OK
Restart inverter, if the error still exist, contact us
The temperature is a little bit high inside inverter
Check AC frequency is in range
Check if battery voltage is in normal range
Check if battery voltage is in normal range, need to
charge the battery if battery voltage is low
Check if there is output from the battery and battery
connection with inverter is OK
Check if EPS load is too high
Restart inverter, if the error still exist, contact us
Restart inverter, if the error still exist, contact us
