Ground current surge.
The internal hardware
that measures ground
fault has measured
substantially high
ground currents.
Ground faults may occur due to
insufficient insulation to the ground.
DO NOT TOUCH UN-INSULATED
WIRES!
EXTREME CARE MUST BE
TAKEN WHEN
TROUBLESHOOTING THIS
ERROR.
THE RISK OF ELECTROCUTION
EXISTS!
Only a qualified technician should
handle this problem, and only after
taking proper precautions.
Shut OFF the inverter by turning the
ON/OFF switch at the bottom of the
inverter OFF and disconnecting the
AC switch.
Wait five minutes for the input
capacitors to discharge.
Disconnect the DC inputs.
For each DC string, measure the DC
voltage between DC- and GND and
DC+ and GND with a 1Kohm resistor
in parallel to the volt meter. If a
voltage higher than 2 V is measured,
then the fault is in this string.
Do not connect strings with a
grounding fault to the inverter.
A certified PV installer must fix the
faulty string before connecting it to
