Sungrow, a global leader in PV inverter and energy storage solutions, has introduced its next-generation residential energy storage system (ESS) at the 2025 Southeast Asia Distribution Summit. This new solution includes the advanced MG Series inverters, which offer power capacities ranging from 5kW to 10kW.
Built with high-performance features such as seamless switching to backup power in just 4 milliseconds, full-power operation even at high temperatures of 45°C, and active PID recovery, the system is designed to deliver reliable and consistent energy for homes across Southeast Asia. It aims to meet the growing demand for energy independence among households, especially in areas with unstable grid conditions or extreme climates.
The MG5/6RL inverters are already available in the market and are compatible with over 50 third-party batteries, providing flexibility for homeowners. The larger MG8/10RL inverters, along with the newly designed MGL060 battery, are expected to launch in the fourth quarter of 2025. The new system is built to grow with users over time. It can scale from 5kW to 80kW by connecting up to eight units in parallel, making it suitable for everything from compact apartments to large homes and future energy expansions. Users can start with a basic setup and expand as needed, whether they are adding batteries later or building a complete off-grid solution.
The system also offers versatile configurations, including options for “Battery Ready,” where the inverter is installed initially and batteries can be added later, and “Backup Only,” where the system functions without PV panels and provides reliable power during outages. A single energy port enables three different functions: Load Management, Diesel Generator Coordination, and PV Expansion, giving homeowners intelligent control over various energy scenarios with a simplified setup.
One of the key advantages of the new ESS is its robust backup capability. The hybrid inverter automatically switches to off-grid mode within just 4 milliseconds during a power outage, ensuring that lights stay on and appliances continue to function without interruption. Despite its compact size, the system can deliver up to 200% overload output for 10 seconds, which means high-power appliances like air conditioners and washing machines can run even during blackouts. The system is also engineered to operate quietly, with noise levels as low as 35 dB thanks to Sungrow’s Immersive Silence technology, creating a peaceful home environment.
In terms of performance, the ESS supports up to 200% DC input and 160% maximum output, allowing simultaneous energy generation and battery charging. For example, a 6kW inverter can produce 6kW of AC output while charging the battery with 3.6kW of DC power. The system supports input currents of up to 20A, making it compatible with a wide variety of PV modules.
It is built to handle extreme temperatures and can maintain full power output even in hot climates, ensuring continuous energy generation and better battery efficiency. Additionally, Sungrow’s patented PID ZERO® technology allows the system to recover from power degradation caused by heat and humidity without needing disconnection or extra hardware, preserving optimal performance of PV modules for up to 25 years.
The user interface is designed for simplicity and ease of use. A 4.3-inch full-color touchscreen provides real-time data and local control, with commissioning possible in less than 30 seconds without internet access. Dual LED indicators give users a quick visual update on system and battery status. The system also includes a convenient “Storm Mode,” which allows users to charge batteries quickly from the grid in preparation for severe weather or scheduled outages. For example, a 6kW/6kWh setup can go from 30% to full charge in just one hour.
Sungrow is also preparing for future enhancements with the integration of iHomeManager, an AI-powered energy management platform. This system will optimize household energy usage based on consumption habits, weather forecasts, dynamic electricity tariffs, and extreme weather alerts, potentially boosting energy efficiency by more than 12%.
The upcoming MGL060 battery, scheduled for release in Q4 2025, features high-capacity 314Ah LFP cells with 8000 life cycles, delivering three times the durability of average industry batteries. It includes pack-level DC/DC optimization, which allows each battery group to function independently. This design also supports mixing new and old batteries without performance loss, ensuring long-term adaptability and efficient energy use for homeowners.
