HOW IT WORKS

DUAK is a Startup recognized in leading Solar Off-Grid MPPT PCU manufacturer making India self-sufficient on solar energy. We use advanced MPPT technology in our Solar Off-Grid PCU that can simultaneously run the load and charge the battery. Suitable for standard Lithium Batteries.

Our Solar Off-Grid MPPT PCU stand apart from the rest because of their high-quality design and multiple features we have packed into it to make your life easier.

Duak Viraj Solar Off-Grid MPPT PCU consists of an MPPT Solar charge controller, Inverter, and a Grid charger all in an integrated form. The Off-Grid Solar PCU is designed to enhance the use of solar power and uses Mains/Grid Power only when solar power is insufficient to meet the load requirements. Duak self-sustaining MPPT PCU has been manufactured by using a world-class technology platform and process as an efficient solution for areas struggling with frequent power cuts. It can be used for domestic, industrial and other events. It provides clean energy for residential and industrial areas without any residual effect. It has a self-adjustable setting that provides superlative performance in all weather conditions. It has a profound mixing of Grid Current with Solar in case of Solar energy insufficiency during cloudy days.

This unique system offers three operating modes- PCU Mode (Our PCU gives first priority to solar, second priority to batteries and third priority to the grid in smart mode), Hybrid Mode (In this mode your PCU works well with solar as well as batteries. Grid charging only takes place when solar power is not available & battery discharges up to battery low-level trip), Smart Mode (Your PCU works in PCU Mode at daytime and in Hybrid Mode at Night.
