Warning
84 Check voltage
settings
The automatically
detected system voltage
does not agree with the
manually set system
voltage.
Take the following measures:
1. Switch off the DC load circuit
breaker (solar module) and
secure it against being switched
on again. With 2 solar modules,
switch off both DC load circuit
breakers.
2. Determine the rated voltage of
the system.
3. Check the following points:
‒ Is the manually set system
voltage the same as the actual
rated voltage of the system?
Correct if necessary!
‒ Does the battery voltage lie
within the range of the rated
voltage of the system? If
necessary, charge the battery
with an external charger.
