The new product lineup includes the PowerStack 255CS BESS for commercial and industrial (C&I) energy storage, the residential PV&ESS system MG5/6RL inverter and MGL060 battery, and the high-efficiency 2.5 kW Microinverter S2500S-L.
These new launches are designed to enhance local energy stability and sustainability while empowering Indian households and businesses with smarter, more reliable power solutions, the company said in a statement.
Sunil Badesra, Country Manager of Sungrow India, said, “Sungrow continues to fulfil its commitment to providing advanced, reliable, and adaptable solutions for the constantly evolving energy landscape in India. By launching new products in the Indian market, combining innovation with validated on-site experience, the company enables partners and customers to meet the growing electricity demand, ensuring that everyone has access to sufficient, safe, and sustainable electricity.”
Sungrow’s PowerStack 255CS integrated energy storage system for the Indian C&I market is equipped with 314 Ah battery cells for 257 kWh capacity in a 2-hour system.
“This highly integrated system, featuring pre-installed and pre-commissioned functions, significantly reduces installation time and costs. Its innovative AI-controlled thermal balance function can reduce daily system heat loss by 33 percent, significantly improving operational efficiency. Meanwhile, precise liquid-cooled balanced heat dissipation maintains more stable battery temperatures, ensuring that the overall temperature difference during operation remains at ≤ 2.5°C for optimised performance,” the company stated.
It further added that safety remains a core focus in Sungrow's system design, as demonstrated by the product's advanced safety architecture: a three-level fire protection design allows the product's precise thermal runaway early warning function to effectively prevent fire; three-level overcurrent protection (PACK, RACK, PCS) provides multiple safeguards for system operation.
“The system supports flexible grid connection, allowing grid-tied, off-grid, and automatic switching. For grid-tied applications, the ST255CX supports up to 25 units, making it an ideal solution for a wide range of application scenarios. Together with the ST510CS in the same series, it delivers a more comprehensive and systematic solution for India's C&I sector,” shared the company.
The newly launched MG5/6RL Hybrid Inverter + MGL060 Battery is engineered for peak performance. The system supports 20A current inputs from mainstream PV panels and features a wide MPPT range with patented PID protection to maximise energy harvest.
“With the allowance of zero power derating at 45°C, seamless backup power switching within 4ms, and parallel connection of up to 8 inverters and 16 batteries, the system ensures households stay powered even in extreme climates or unstable grid conditions,” the company said.
It further added that the new MGL060 battery, equipped with a 314Ah high-capacity battery, IP65 waterproof rating, and C5-M corrosion resistance, ensures its robust durability for up to 15 years. “Built with flexibility, the system supports whole-home backup retrofits or new installations, and compatibility with diverse batteries and diesel generators — offering a comprehensive, adaptable solution for diverse residential energy needs,” the company stated.
The new S2500S-L is purpose-built for residential applications, featuring a nominal power of 2.5 kW and four independent MPPTs with 18A of operating current.
“Microinverters are often installed in tight spaces between solar panels and rooftops, where summer heat can cause conventional devices to reduce output or shut down. The S2500S-L is built to perform well in these conditions, operating at 45°C without power derating and maintaining reliable output up to 80°C,” asserted the company.
The S2500S-L features one-click configuration, offering an install-friendly design that allows for plug-and-play operation. It supports both DC and AC wiring, providing great convenience for installation and use. “With rapid shutdown in compliance with IEC 63027 and a low DC input voltage, the system delivers exceptional safety performance – setting a new benchmark for residential inverter reliability in India,” stated the company.
