AGC-4 MK II

The automatic genset controller AGC-4 Mk II is the world’s most comprehensive genset controller offering all necessary functions for protection and control

Read more

You can easily integrate renewable and sustainable power sources such as solar (PV) panels and BESS in your critical power solution using DEIF sustainable controllers that interface with the other controllers in the PMS. Any power application with more than one power source type by definition is a hybrid power system that gives you a range of options.

When one or more power sources are renewable, you can configure your system to prioritise renewable power (using PV or wind, or sustainably generated power from your BESS) for as long as it is safe to do so, switching to mains or generator power if renewable production drops.

You can configure your system to prioritise low-cost power (only running on mains when utility rates are low, for example).

Finally, you can configure for uninterrupted power (prioritising reliable sources such as generators, possibly combined with charging your BESS from renewables).
