Residential and commercial energy storage systems, equipped with photovoltaic inverters and energy storage PCS, simultaneously involve AC grid connection and DC battery circuits, making them highly susceptible to mixed AC/DC leakage. Peak-valley voltage fluctuations in the grid can damage the energy storage batteries. Furthermore, time-sharing charging and discharging control is required, and long-term outdoor operation demands extremely high circuit protection levels.

Rynova's self-developed Type B leakage protection chip, self-resetting over/under voltage chip, and multi-functional timing control IC can accurately capture AC/DC residual current, monitor grid voltage anomalies in real time, customize energy storage charging and discharging periods, and features an industrial-grade wide-temperature design suitable for outdoor energy storage cabinets. It meets photovoltaic energy storage safety standards and ensures stable operation of the energy storage system.
