The GoodWe SBP series is the world’s first AC-coupled battery storage retrofit solution with UPS function for single-phase and three-phase systems. It can effectively upgrade any existing string inverter system by adding a backup battery. Capable of being grid-interactive, it allows users to store surplus power and sell it back to the grid when demand peaks and the price of electricity is at its highest. With a UPS-level switching function (switching time <10 ms), the GoodWe SBP provides an uninterruptible power supply to inductive loads such as air conditioners or refrigerators. It runs reliably under even the most extreme conditions with metal aluminium housing with IP65 protection.
