Hailei is the battery storage and hybrid inverter brand of Shenzhen HaiLei New Energy Co., Ltd., a national high-tech enterprise founded in 2012 that designs, manufactures and tests its own lithium battery packs and storage systems. We use Hailei's ATOM battery range and hybrid inverters across our residential installations, chosen for its UK-relevant certification, IP65-rated build quality and UK-based support.
The Hailei range we fit spans the ATOM WB wall-mounted battery (5.12kWh, LiFePO4), the ATOM HS high-voltage stackable battery (15.36kWh up to 40.96kWh in modular steps), and the floor-standing LV series residential energy storage system (10.24kWh and 16.08kWh). On the inverter side, Hailei's single-phase hybrid storage inverters cover 1–6kW and three-phase units cover 3–30kW, all with AI-based electricity pricing automation, UPS switchover under 10ms, and up to 150% peak output overloading for backup.
Hailei's battery and inverter products are independently tested and certified to UK G98/G99, UKCA, CE, UL, TUV, IEC 62619, IEC 62109, IEC 62477 and UN38.3 standards, and the company holds ISO 9001, ISO 14001, ISO 45001 and IATF 16949 management system certification — the certification our team checks before any Hailei unit goes on a customer's wall.
Hailei operates two manufacturing bases and an in-house R&D and test lab in Shenzhen, with a UK office supporting installers directly. Full technical specifications for every Hailei battery and inverter we fit are set out in the product catalogue below.
