Box phase missing
: One line
conductor of a Sunny Island in-
verter is missing.
• Ensure that all circuit breakers of
the Sunny Island inverters in the
Multicluster-Box are closed.
1. Search for the missing line
conductor and eliminate the error.
For this, with loads connected,
measure the AC voltage between
each line conductor and between
the line conductors and the neutral
conductors. If an AC voltage
deviates from the nominal voltage
by ±10%, the corresponding line
conductor is missing.
2. Reset the off-grid system. For this,
disconnect the off-grid system and
restart.
