1. Description of system

Solar-diesel generrator hybrid power system consists of solar panels, diesel generator, solar&diesel generator integrated controller and battery. Solar-diesel generator hybrid system can resist the rainy days and power the loads consistently all the year, is the best solution for solar power systems when rainy days.

when battery voltage goes down to the set value. the controllerwill start the diesel generator automatically, when the battery is charged to the set value, the controller will turn off the diesel generator automatically.

Solar-diesel generator hybrid system can reduce the working time of diesel generator under light loads and the consumption of fuel and failure rates of diesel generator to improve the working efficiency of diesel generator and reliability of systems.

2. Project case

China Unicom-3400Wp solar panels+400W loads+60 hours back-up solar diesel generator hybrid system in Altay, Xinjiang Autonomous region.
