Check whether the current sensor values (I grid L1, I grid L2
and I grid L3) are realistic:
If a current sensor value is approx. 0, although the phase is
currently loaded, the connection between current sensor and
energy storage system might be faulty.
If necessary, load all phases separately: Switch on consumers
deliberately.
If necessary, check the current through all three phases with
the clamp-on ammeter!
Measures in case of suspicious current sensor values:
Check whether the connection corresponds to a clockwise
phase sequence.
If the current sensor value of one or several phases is 0 in
spite of a load, check the connection between energy
storage system and current sensor.
If necessary, replace the connecting cable (RJ12 cable).
Checking the battery inverter
11.3.2
On the
System
page, check the operating state of the battery
inverter for plausibility.
