Frequently asked questions

We have put together some commonly asked questions

The PV production is automatically adjusted so as to have a maximum PV penetration while ensuring the gensets do not run below the minimum loading value (typically average 30% of genset nominal capacity)

The zero export feature is included in all or our controllers. They curtails solar power to enable a maximum PV production, while ensuring zero export to the grid, thus avoiding penalties from the grid operator. It also allows to feed power into the grid, in accordance with the grid operator guidelines and standards, as well as the ability to set grid targets autonomously by the operator.

The controller includes the minimum genset loading feature which ensures a certain level of reverse power protection, but not entirely. It’s therefore important to install a reverse power protection.
