Wedoany.com Report-Nov. 28, Sungrow, a leading Chinese manufacturer of inverters and energy storage systems, has launched its new PowerKeeper series, a commercial and industrial (C&I) battery energy storage solution featuring a fully DC-coupled, one-stop system with modular architecture.

Built on Sungrow's "Ace 007, Ace Profit" design philosophy, the PowerKeeper series aims to provide seven core advantages that ensure zero waste, zero outages, and seamless operation throughout the product lifecycle.

The system adopts a 12.5 kWh battery pack configuration that enables flexible capacity scaling. A single unit can reach up to 250 kWh, while one hybrid inverter supports applications from 50 kWh to 1,000 kWh with discharge durations of 2–8 hours. Multiple inverters can be paralleled for virtually unlimited expansion.

An optional long-duration combiner box allows connection of 2–4 battery clusters, further extending capacity to 1,000 kWh and supporting up to 8 hours of energy storage in a single integrated setup.

The modular and standardised design simplifies installation, maintenance, and future upgrades, making the PowerKeeper series suitable for a wide range of commercial and industrial energy storage requirements worldwide.
