Backup operation (grid outage) – backup operation stops
Backup operation stops. The miniature
circuit breaker (MCB) in the supply line
to the sonnenProtect and the circuit
breakers in the backup circuit have not
tripped. The Eclipse on the storage
system pulses
green and goes off after
several minutes. The illuminated switch
on the sonnenProtect
does not light
up .
The backup buffer of the storage sys-
tem batteries is depleted. The batteries
have discharged so much that further
discharging would lead to a deep dis-
charge state and therefore damage
the batteries. There is nothing that can be done be-
sides wait until the grid outage is done
and the public electricity grid once
again begins supplying electrical en-
ergy. The sonnenProtect will then
automatically switch to grid operation.
Backup operation stops. The miniature
circuit breaker (MCB) in the supply line
to the sonnenProtect or a circuit
breaker in the backup circuit has
switched off. The Eclipse on the stor-
age system pulses
green . The illumin-
ated switch on the sonnenProtect
does not light up .
The residual current device (RCD) or an-
other circuit breaker in the backup cir-
cuit has tripped.
Check the electrical wiring and the
connected electrical consumers for
faults.
Switch on the circuit breaker once any
faults are corrected.
Backup operation stops. The miniature
circuit breaker (MCB) in the supply line
to the sonnenProtect and the circuit
breakers in the backup circuit have not
tripped. The Eclipse on the storage
system pulses
orange . The illuminated
switch on the sonnenProtect lights up .
Electrical consumers with too high of a
power consumption are connected to
the backup circuit. Switch off electrical consumers in the
backup circuit or reduce their power
consumption.
Press the illuminated switch on the
sonnenProtect for approx. 2 seconds.
Backup operation restarts.
Only connect electrical consumers to
the backup circuit when they have a
power consumption that does not ex-
ceed the maximum power (see Tech-
nical data [P. 89]).
