Residential Energy Storage Systems (RESS) are dedicated energy storage solutions designed for household use, typically integrated with renewable energy systems such as rooftop photovoltaics to achieve electricity storage, management, and intelligent scheduling.

The ​Microcontroller Unit (MCU) dynamically optimizes photovoltaic array output efficiency by continuously collecting real-time parameters such as light intensity, panel voltage/current, and applying ​MPPT (Maximum Power Point Tracking) algorithms to minimize energy losses. Simultaneously, the MCU drives ​bidirectional inverters to perform DC-AC conversion, supports seamless switching between off-grid and grid-connected modes, and interfaces with ​Home Energy Management Systems (HEMS) via ​Wi-Fi/Bluetooth communication modules to optimize power usage strategies and enable remote monitoring.

Watech Electronics provides comprehensive semiconductor solutions for RESS, including ​high-performance Super Junction IGBTs, ​BMS (Battery Management System) chips, and ​main control MCU chips, enabling the design of high-frequency, high-efficiency residential energy storage systems (3-50kW systems).
