Operating states
(only for systems
with a battery) Battery system distinguishes different operating states. The current operating
state is displayed on the system monitoring website or in Solar.web.
Operating state Description
Deactivated
The battery is not active. It has either been deac-
tivated, or no communication with the battery or
meter is possible due to a fault.
Normal operation The system is in normal operation
Service mode
1)
Service mode has been activated. The battery is
automatically charged or discharged to a defined
SOC value and then kept at this value until service
mode is ended manually.
Forced re-charging
The Fronius Symo Hybrid recharges the battery to
counteract self discharge and maintain the set
minimum SOC (protection against deep dis-
charge).
Min. SOC reached
The battery has reached the set minimum SOC.
The battery cannot be discharged further until
charging takes place again.
Energy saving mode
The system has been put into energy saving mode.
None of the LEDs or the battery display light up
1)
.
Energy saving mode is automatically ended as
soon as sufficient excess energy is available again.
Calibration mode
1)
The system is in calibration mode. When there is
insufficient PV energy available to reach 100%,
the battery is cyclically charged to 100% for in-
ternal calibration. Under certain conditions (de-
pending on weather, microcycles, temperature,
etc.), this can take an extended period of time.
Deep discharge protec-
tion
1)
The Fronius Symo Hybrid recharges the battery to
counteract self discharge and maintain the minim-
um state of charge.
