Sungrow launches next-gen hybrid residential energy storage system

China’s Sungrow Power has revealed its newest hybrid, next-generation residential energy storage system (ESS), with its  latest MG Series 5/6RL already on the market. An MG8/10RL model, and matching MGL060 battery, will be released in Q4.

The upgraded MG8/10RL covers power ranges from 5 kW to 10 kW and offers full-power operation at 45 C, active potential induced degradation (PID) recovery, and backup power switching within 4 milliseconds, which Sungrow says ensures households stay powered in extreme climates or unstable grid conditions and meets a rising demand for household energy independence.

Matched with the new MGL060 battery, the system can support eight units in parallel to suit apartments or large homes, and is compatible with mainstream third-party batteries.

“The MGL060 features large-capacity 314 amp hours (Ah) lithium iron phosphate (LFP) cells with 8,000 cycles ([and an] end-of-life [EOL] [value of] 60%), delivering triple the lifespan of average industry offerings. Its pack-level direct-current (DC)/AC 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,” the company said.

With up to 200% DC input and 160% maximum output capacity, Sungrow said the system will deliver high performance. For example, a 6 kW inverter can simultaneously provide 6 kW of rated alternating current (AC) output while charging the battery with 3.6 kW of DC power—ensuring maximum energy utilization.

“Engineered to support up to 20 amperes (A) input current, the system is compatible with virtually all solar modules on the market. No DC energy goes to waste – enabling greater efficiency and seamless integration with your existing or future solar setup,” a company statement read.

“Built for extreme conditions, the system maintains full power output even at 45 C ambient temperature. It ensures stable generation during peak heat hours, boosts self-consumption, and conserves battery power for when it’s truly needed – delivering reliability when it matters most.”

The system can also be prepped for forecast extreme weather or scheduled outages, with a single click activating fast battery charging from the grid, and go from 30% to 100% state-of-charge in 60 minutes (based on a 6 kW/6 kWh system).

Featuring the company’s patented ‘PID Zero’ technology, Sungrow said the system is also the industry’s first to actively recover from PID effects without disconnecting from the grid and counteracts long-term power loss caused by heat and humidity – ensuring solar modules stay efficient for 25 years and requiring no extra hardware or rewiring.

Grid outage

In the event of a grid outage, the hybrid inverter automatically switches to off-grid mode within 4 ms, ensuring uninterrupted power without light flicker or appliance shutdown, and delivers up to 200% overload output for 10 seconds.

For example, Sungrow said, the MG6RL model can supply 12 kW to instantly support high-power appliances like air conditioners and laundry-washing machines during blackouts.

Later integration with Sungrow’s iHomeManager, a forecast-based energy management system, will use artificial intelligence to tailor energy strategies based on usage patterns, weather forecasts, dynamic electricity tariffs, and extreme weather alerts, optimizing energy dispatch and boosting household green energy benefits by more than 12%.

The company added that data based on households configured with a solar–ESS–electric vehicle charging system, and heat pumps, may see varied actual benefits depending on load types and capacity.
