Renewable energy is the revolution for world energy, but it is not stable and controllable, whereas batteries involved in to save the problem. Tianneng Energy Storage Battery is designed to adapt different situation when dealing with renewable energy. Floating and cycling performance of the battery is vital for battery used in renewable energy systems as batteries used as an transfer space for solar or wind at most time and waited for release when it is needed. In regions with poor grid system, the TNC lead carbon series is perfect when you can not guarantee the battery is fully charged, the carbon material maintain a remarkable performance even at partial statue of charge(PSOC) situation.
