6 Self test
A self test of the solar charge controller can be executed if
required. An adjustable, stabilised power supply unit with
current limiting is required for the self test.
1.
Disconnect all connections to the solar charge controller and
wait for at least 1 minute.
2. Adjust the power supply to a voltage of 7.25 V (± 0.25 V)
and set the current limit to max. 2 A (0.5 A to 2 A).
3. Connect the power supply unit with the correct polarity to
the solar module terminals.
The self test starts automatically. The results are displayed
according to the following table:
