PVI 1800/PVI 2500(Rev A)
5 Troubleshooting
Diagnosis and analysing data
Identifying and resolving faults
The PVI 1800/PVI 2500 is fitted with a self-diagnostic system, which can recognise a majority of
possible faults and show these on the display. This allows the operator to rapidly identify possible
problems in the solar inverter or system.
Internal communication errors
Internal communication errors are indicated when a problem arises in the device. The technician
responsible for servicing the device should be informed if the problem has been occurring over a long
period of time.

External faults
External faults are primarily faults caused by the utility company but can also be associated with
mounting of the inverter and length of the AC lines; they concern the frequency and voltage. Such faults
can also occur temporarily. The PVI 1800/PVI 2500 will, however, resume full automatic power feed
after a short interruption. If the grid frequency or voltage is more or less that values prescribed by
UL1741/IEEE1547, the inverter will not re-start for 5 minutes and will display: "wait for restart" on the
LCD display during this 5 minute period.

Grid frequency too low
Condition
The device resumes
feeding the grid with
power when automatic
switching on of the
inverter reconnects it with
the power grid
Condition
The inverter switches over to
normal power/feed mode as soon
as the grid frequency returns to its
nominal value.
