KW3 - Plug-and-play solar system for off grid applications

KW3 is a robust, reliable plug-and-play solar generator with zero CO2 emissions that supplies electricity 24/7.

The solution aims to reduce grid dependance and supply back-up in the event of power failure. For off-grid applications, it can be coupled to a diesel genset and used as a hybrid system. This provides longer servicing intervals and extends the operating life of the diesel genset. The application may be temporary or permanent while offering low maintenance, no moving parts and improved energy resilience. The intelligent system used in KW3 operates autonomously. KW3 is protected against surcharges, and it filters out harmonics which can affect power quality. Specific customer needs are addressed thanks to the different parameters available.
