Generator Run Times
Generator run times specify time frames for generator operation. The generator run times are only interrupted in the event of a fault. This allows the generator management system to operate the generator with as little wear as possible and energy-efficiently. The energy efficiency increases due to the generator management system being able to use an operating generator for as long as possible at a high generator efficiency.
You can adjust and optimize the run times to suit the generator and the off-grid system requirements.

Generator run time |
Explanation |
|---|---|
|
Warm-up time |
So as not to subject the generator to a load when it is cold, the generator warms up during the warm-up time. The warm-up time reduces generator wear. After the warm-up period, the Sunny Island connects the stand-alone grid to the generator. |
|
Minimum run time |
The minimum run time begins after the warm-up time has ended. During the minimum run time, the generator supplies current in order to charge the battery and to supply the loads. The minimum run time prevents short generator run times. |
|
Power-down time |
Once the minimum run time has expired and the reason for the generator request no longer exists, the generator management system disconnects the generator from the stand-alone grid. The power-down time starts upon disconnection. During the power-down time, the generator operates without a load and the operating materials slowly cool down. |
|
Minimum stop time |
The minimum stop time begins after the power-down time. The generator does not operate during the minimum stop time. In this way, the generator management system prevents frequent generator starts. Frequent starts result in the generator motor wearing faster. |
