Overview

Sungrow's all-in-one residential energy storage system, unveiled at Intersolar Europe 2026. Modular design lets homeowners mix 6-10 kWh battery modules (built on 314 Ah large-format cells) for a stackable capacity range up to 120 kWh at 10-30 kW of power. Supports up to 1.6x PV-to-battery charging and 0.66P charge/discharge capability, which Sungrow says is up to 32% higher throughput than conventional 0.5P residential systems, and can pair new modules with previously installed ones.
