The use of solar power and other renewable energy sources, which have unstable output, continues to increase, power supply to the entire grid could become unstable. We need a battery energy storage system to stores electrical power.

And grids deliver electricity in real-time, meaning electricity is being consistently produced to meet consumer demand. As a result, electricity generation systems are built to meet peak demand. Battery energy storage enables a lower cost generating source to produce electricity at a different point in time to be stored and then used to meet times of peak demand.

Polinovel BESS20 comes with 20.6kwh of reserve electricity, measures 1103mm*703mm*403mm is protected by SPCC steel with 250℃ high-temperature baking paint housing. It weighs 260kg and is equipped with a rolling foot wheel and fixed leg that make moving easier. Unlike diesel generators, the BESS batteries are silent, perfect for use around tranquil locations.
