Errors and Troubleshooting
Description
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.
ELECTROCUTION RISK
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 the
inverter.
