Back-up generator

In PVsyst, the back-up generator is considered only as an alternator+rectifier element (Genset), ensuring the recharging of batteries when the solar energy is insufficient to meet the user's needs.

You can specify a nominal power, as well as an operating power, for which the efficiency may be lower.

Its parameters comprise only the definition of the nominal power supplied, as well as a specific fuel consumption (in volume per hour) to evaluate the back-up consumption.

Provision is made for defining commercially available devices (sizes, weight, etc.), but none are currently proposed in the database.
