Auto test failure
Auto test failed
Inverter fails to communicate with
the meter
Bat Fault
Battery cannot charge or discharge
1. Check the battery communication cable for
correct pinout on both inverter and battery end;
1. Check if the communication cable is connected
correctly and in good condition.
Lcd com failure
LCD fails to communicate with M3
microprocessor
Trip by gfci high

GFCI module fault
Inverter detected high DC injection
current on grid port
Battery is disconnected from
inverter
Battery voltage too low
Inverter detected leakage current
on AC side
Inverter detected short circuited
PV input
GFCI module is abnormal
1. Check if each PV string is connected correctly;
Restart inverter. If fault still exists, contact
Luxpower service or your inverter supplier.
Check if battery voltage exceeds 59.9V, battery
voltage should be within inverter specification.
Fwm mismatch
Fan stuck
Firmware version mismatch
between the microprocessors
Cooling fan(s) are stuck
Bat volt high
Battery voltage too high
2. Restart inverter. If the fault persists, contact
Luxpower service or your inverter supplier.
Only applied to Italy model
PV arc fault is detected
AFCI high
Check each PV string for correct open circuit
voltage and short circuit current. If the PV strings
are in good condition, please clear the fault on
inverter LCD.
Meter com failure
2. Check if you have chosen an incorrect battery
brand;
3. Check if there is fault on battery's indicator. If
there is fault, please contact your battery supplier.
Restart inverter. If fault still exists, contact
Luxpower service or your inverter supplier.
1. Check if there is ground fault on grid and load side;
2. Restart inverter. If the fault remains, contact
Luxpower service or your inverter supplier.
Restart inverter. If the fault remains, contact
Luxpower service or your inverter supplier.
2. Restart inverter. If the fault remains, contact
Luxpower service or your inverter supplier.
Check if battery voltage is under 40V, battery
voltage should be within inverter specification.
Check battery breaker or battery fuse.
Meter reversed
Offgrid overvolt
Meter is connected reversely
EPS voltage is too high
Check if load power on inverter EPS port is within
inverter specification.
Offgrid overload
Overload on EPS port
Restart inverter. If fault still exists, contact
Luxpower service or your inverter supplier.
Check if meter communication cable is connected
correctly on inverter and meter side.
RSD Active
Offgrid dcv high
Rapid shutdown activated
High DC voltage component on
EPS output when running off-grid
Restart inverter. If fault still exists, contact
Luxpower service or your inverter supplier.
Check if the RSD switch is pressed.
2. Alarm on the LCD
If the dot on the left of fault item is yellow, it means the fault is active. When it is grey, it means the fault is deactive

Check if communication cable is correct, and if you
have chosen the correct battery brand on inverter
LCD. If all is correct but this error persists, please
contact Luxpower service or your inverter supplier.
Restart inverter, if the error persists, contact
Luxpower service or your inverter supplier.

Restart inverter, if the error still exists, contact
Luxpower service or your inverter supplier.
Check if the neutral wire is connected correctly.
Disconnect all PV strings from the inverter. If the
error persists, contact Luxpower service or your
inverter supplier.
Install the inverter in a place with good ventilation
and having no direct sunlight. If the installation site
is okay, please check if the NTC connector inside the
inverter is loose.
Restart inverter, if the error still exists, contact
Luxpower service or your inverter supplier.
