The rising global demand for solar, wind, and other clean energy has seen the market grow exponentially over the last few years, with the trend predicted to continue. Due to the inherent limitations of renewable energy, the lithium battery energy storage industry develops rapidly. And people in urban and rural areas often have to encounter power cuts and irregularities in power distribution during peak times.

Polinovel lithium home energy storage system can store electricity for you effectively. It reduces your reliance on the grid by storing your solar energy for house appliance use. Keep power stays on when grid outages.

Installing a Polinovel home battery with a solar energy system allows you to maintain a sustained power supply during the day or night, as long as you store enough power from your panels when the sun is shining.

Polinovel stackable modular design energy storage system integrated inverter and battery modules, support up to 15 batteries for flexible power expansion and easy installation. The battery adopts the highest-grade lithium iron phosphate cell, combined with scientific and reasonable internal design and fine processing, which prolongs the system lifespan safely and effectively.
