The company designs, manufactures, and deploys LFP-based energy storage solutions across three product lines: residential ESS (4.99-29.94kWh, including single-phase PP-S2 and three-phase PP-T1 systems), commercial and industrial ESS (100-250kW / 233-509kWh, including all-in-one PC-G1/PC-G3 and modular PC-G2 configurations), and utility-scale systems (744-1,488kW / 1,490-2,980kWh, including PA-3.0EU). Battery cells are sourced from CATL at 280Ah, 306Ah, and 314Ah capacities.

The company's core technology differentiator is the proprietary WHES OS energy management platform, an AI-powered EMS featuring cloud-edge-device synergy, predictive dispatch, sub-20ms on/off-grid switching, full-spectrum cell temperature and voltage monitoring, multiple redundant protections, and SOH-based cell lifespan prediction. The platform exposes open APIs for VPP and grid dispatch integration and supports protocols including 103, 104, and IEC61850. Products carry international certifications (UL9540A, VDE 4110, IEC 62933, UN38.3, UL1973, IEC62619, and European grid codes PTPIREE and C10/C11).

WHES operates a B2B enterprise field-sales go-to-market targeting C&I customers, utility and grid operators, and government institutions across Europe, Australia, China, Southeast Asia, and the Middle East, supported by 20+ global service centers and 800+ deployed projects in 50+ countries serving 40+ industries. Revenue is generated through hardware system sales, software (WHES OS), and pre-/after-sales services under quote-based enterprise contracts. The company completed a Series B financing in February 2026 of hundreds of millions of RMB (recorded at 200,000,000 CNY) with overseas investors and existing shareholders, with proceeds earmarked for AI capability enhancement, global expansion, and intelligent manufacturing upgrades.
