8 Troubleshooting
Fault
Possible causes
Rectification
Grid operation (no grid outage)
The electrical consumers in the
backup circuit are not supplied with
energy in grid operation.
The lines of the backup circuit have not
been connected correctly.
Contact your installer to check the elec-
trical wiring.
The miniature circuit breaker in the sup-
ply line of the sonnenProtect is
switched off.
Switch on the miniature circuit breaker in
the supply line of the sonnenProtect.
The miniature circuit breaker (F3.P) in
the sonnenProtect is switched off.
Switch on the miniature circuit breaker
(F3.P) inside the sonnenProtect.
The RCD (F4.P) in the sonnenProtect is
switched off.
Switch on the RCD (F4.P) inside the
sonnenProtect.
Backup operation (grid outage) - Backup operation does not start
Backup operation doesn’t start. The
eclipse of the storage system is
off
.
The batteries of the storage system
have discharged so much that further
discharging would lead to a deep dis-
charge state and therefore damage the
batteries.
If the PV system generates electrical
power, the backup operation will continue
as soon as excess power is available.
If the PV system does not generate elec-
trical power the only thing to do is wait
until the grid outage passes and the public
electrical grid once again starts supplying
electrical energy. Then the sonnenProtect
automatically switches to grid operation.
The storage system is switched off.
Switch on the storage system.
Backup operation doesn’t start. The
eclipse of the storage system is
green
.
The miniature circuit breaker (F3.P) in
the sonnenProtect is switched off.
Switch on the miniature circuit breaker
(F3.P) inside the sonnenProtect.
The RCD (F4.P) in the sonnenProtect is
switched off.
Switch on the RCD (F4.P) inside the
sonnenProtect.
Backup operation doesn’t start. The
eclipse of the storage system is
or-
ange
.
Electrical consumers with too high
power consumption are connected to
the backup circuit.
Switch off electrical consumers or reduce
their power consumption.
Only connect electrical consumers to the
backup circuit when they have a power
consumption that does not exceed the
nominal power or (when switching on) the
maximum power of the sonnenProtect.
