14.1.4 Manual Generator Operation
The manual operating modes for the generator management are tripped using the
"540.01 GnManStr" parameter. Here, a distinction is made between the following operating modes:
An equalization charge can be manually started using the "520.01 ChrgSelMan" parameter.
This sets the battery management (see Section 13 "Battery Management", page 106) in the
equalization charge state and the generator is requested. This request persists until equalization
charge has been completed.
The following flowcharts provide an overview of the start/stop behavior of the Sunny Island during
manual generator operation:
Generator Interface "234.07 GnStrMod" = Manual; Start at the Generator
Auto: In this operating mode, the generator is automatically started due to the settings.
This includes the start via the state of charge or the load power or by the request for
a manual equalization charge.
("520.01 ChrgSelMan" = Start).
Stop: The generator is manually stopped. The current generator request is canceled –
immediate disconnection from generator and change to lock state. Once the lockout
time has ended, the generator switches into automatic operation.
Start: Manual generator start – the generator runs "continuously" until stopped.
The generator can only be manually stopped.
Run1h: Operation for one hour. Once the lockout time has expired, the transition back into
automatic mode follows.
1 Manual generator start
2 "Generator is running" detected, beginning of warm up phase
3 Internal generator request is ignored
4 Warm-up phase is completed, generator is connected
5 Generator current limit
6 Current is reduced, battery absorption phase
7 Manual generator stop, disconnection of the generator
8 Minimum stop time has expired
