voltage
The automatically
detected system voltage
cannot be matched to
any of the voltages 12 V/
24 V/ 48 V.
Take the following measures:
1. Switch off the DC load circuit
breaker (solar module) and
secure it against being switched
on again. If using both string
inputs then 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.
