11 Troubleshooting

Your PV-Inverter requires very little maintenance. When an unexpected situation
occurs, please refer to the following table before calling your local service. The
following table lists common error messages and ways to cope with the fault or
error.
Error Message
ERR GROUND
FAULT
ERR ISOLATION
ERR GRID
NO GRID
DC OVERVOLTAGE
- ENGLISH -
Error definition
The ground
detected by inverter
higher than threshold
The DC insulation
resistance between
generator and ground is
lower than "Minimum
allowed PV generator
insulation" in "Table 1" in
the appendix
Grid measured data
beyond the specification
(voltage & frequency) (see
"Table 2" in the appendix)
Inverter is not able to
detect AC voltage
The detected PV voltage is
higher than specification
Possible Action
current 1. Check cable glands and gaskets are
is properly installed.
2. Check
resistance with respect to ground as
described in paragraphs 12.1 and 12.2.
3. Check the Neutral to ground voltage: it
should be lower than 10V
PV
4. Please check the system satisfies the
requirements of paragraph 5.3
5. Check the resistance of the ground: it
should
paragraph 5.4
6. If the aforementioned checks do not solve
the problem, please call service
Measure the grid voltage on the inverter's
output terminal block and on the meter
terminals. If, after the inverter has started to
feed the grid, the voltage increase is greater
is
on the inverter terminal block than on the
meter, please check all the connections
between these two points and verify the cable
section is adequate to its length. If the
voltage increase is almost equal, please ask
your electricity supplier to adequate the
power line.
Measure AC voltages on inverter's output.
If not all present, check the electrical plant.
If present, call service.
Check PV open voltage. If lower than "Max.
open DCV" (see "Table 1" in appendix), call
local service.
