Electrical Generator Thresholds

Maximum generator current

The generator management system limits the consumption of generator current to a set maximum value. This prevents the generator from becoming overloaded.

Frequency of generator voltage

The thresholds for the frequency and magnitude of the generator voltage define the range within which the Sunny Island and the generator operate. These thresholds directly affect the power quality in the stand-alone grid.

Generator voltage magnitude

Maximum generator reverse power

Reverse power in the generator can occur if AC sources in the stand-alone grid supply more current than is required in the off-grid system. The generator is powered by the generator reverse power. Depending on the generator, the generator reverse power leads to the automatic disconnection, instability or destruction of the generator.

You can set the active power of the reverse power and the permitted time for reverse power. If the reverse power exceeds the thresholds, the generator management system disconnects the generator from the stand-alone grid. This protects the generator.
