Which type of generator connection do you need?

Parallel (non-exporting) generators

Non-exporting generators, operate in parallel with the electricity distribution system. Such generators cannot be used to supply or sell electricity via the national grid.

Standby generators

Standby generators are used by businesses that require emergency generation. They cannot be used to export or sell electricity onto the electricity network. In addition, they cannot operate in parallel with the electricity network.
