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.

Code

Designation

Condition

Solution

101

Hardware error, internal communication
interrupted

The device resumes
feeding the grid with
power when automatic
switching on of the
inverter reconnects it with
the power grid

The service technician
should be informed if this
error code has been seen
repeatedly or
continuously.
