Details on Sungrow’s new MG Series residential energy storage system
Sungrow unveiled its next-generation residential energy storage system (ESS) at 2025 Southeast Asia Distribution Summit. Featuring the upgraded MG Series inverters, this new solution covers power ranges from 5 kW to 10 kW. Highlight features include full-power operation at 45 °C, active PID recovery, and seamless backup power switching within 4ms.
MG5/6RL inverters are already available and compatible with over 50 third-party energy storage batteries. MG8/10RL models and the matching MGL060 battery will be released in Q4 2025.
Sungrow MG Series highlights
The system scales effortlessly from 5kW to 80kW with support for up to eight units in parallel.
The system adapts—from PV-only setups to fully off-grid solutions. It also supports versatile configurations, including “Battery Ready” (install the inverter now and add batteries later) and “Backup Only” (a hybrid system without PV panels, offering reliable power during outages).
One port is designed for three smart applications: Graded Load Management, Diesel Generator Coordination, and PV Expansion.
The system delivers up to 200% overload output for 10 seconds. For example, the MG6RL model can supply 12kW to instantly support high-power appliances like air conditioners, laundry machine during blackouts—making it both reliable and powerful.
Speaking of 200%, with up to 200% DC input and 160% maximum output capacity, a 6kW inverter can simultaneously provide 6kW of rated AC output while charging the battery with 3.6kW of DC power.
Can support up to 20A input current to be compatible with virtually all PV modules on the market. No DC energy goes to waste—enabling greater efficiency and seamless integration with your existing or future solar setup.
The system maintains full power output even at 45 °C ambient temperature.
Featuring Sungrow’s patented PID ZERO technology, the system actively recovers from PID effects without disconnecting from the grid. It counteracts long-term power loss caused by heat and humidity—ensuring your PV modules stay efficient for 25 years, no extra hardware or rewiring required.
The 4.3-inch full-color touchscreen offers real-time monitoring and complete local control. Sungrow says commissioning takes less than 30 seconds—no internet required.
Prepare for extreme weather or scheduled outages with a single click—activate fast battery charging from the grid and go from 30% to 100% SOC in just one hour (based on a 6kW/6kWh system).
Coming Soon: MGL060 battery
Launching in Q4, the new MGL060 battery features large-capacity 314 Ah LFP cells with 8000 cycles (EOL 60%), delivering triple the lifespan of average industry offerings. Its pack-level DC/DC energy optimization works like a dedicated optimizer for each cell group, ensuring each operates independently and efficiently, even when new and old batteries are mixed.
