Plug-in Home Energy Management (Balcony Storage) for the AI Era
Guangzhou Jianghai Technology Co., Ltd., operating under the brand Zendure and founded in 2017, closed a several-hundred-million RMB Series B round at the end of 2025 with strategic investment from Han’s Laser and Delian Capital. In the first full quarter after closing, revenue grew roughly 200% year over year.
Company Overview
Zendure pioneered plug-in home energy management, or balcony storage, building a four-layer platform of hardware, data, software, and service. By 2026 it leads core European markets including France, Germany, and the Netherlands in reputation, acceptance, and sales.
Why Balcony Storage Wins
Traditional home storage in Europe costs between 10,000 and 30,000 euros with weeks to months of professional installation. Zendure’s plug-in units deploy in under five minutes at around 1,000 euros, roughly one-tenth the cost, with payback of three to five years, or under two years with AI and dynamic tariffs. BNEF (2025) recorded global storage additions of 94 GW and 247 GWh, up 35%, with balcony storage the fastest-growing edge.
Product & AI Stack
The SolarFlow series, from Hub 2000 through 2400 and Mix Pro/AC+, anchors the ecosystem, with April 2026 flagships sold out through July. HEMS 2.0 and its ZENKI AI are trained on 200 billion real home charge and discharge records plus the ZenPulse time-series model, forecasting seven-day usage and making charge and discharge decisions multiple times per second. ZENKI Mode saves up to 73% on dynamic tariffs versus roughly 20% for peers.
The platform connects 840-plus utilities, 5,000-plus heat-pump models, and more than 1M EV chargers, covering 100% of rooftop PV. ZenWave buys wholesale power, retails it at a dynamic tariff, and auto-arbitrages through SaaS, with the first Dusseldorf and Leipzig users saving over 100 euros per month. The business model is shifting toward hardware plus subscription plus a per-kWh split, with virtual-power-plant aggregation ahead.
Strategic Investor
Han’s Laser is building a Switzerland headquarters and a dedicated factory of more than 1M units per year with laser-welding automation, providing deep manufacturing and globalization support.
Investment Highlights
Zendure is a category creator in a market worth over 100 billion euros incrementally, with a data and AI moat of 200 billion records that compounds with scale. Recurring revenue through ZenWave SaaS and virtual power plants, combined with industrial-capital validation from Han’s Laser, underpins the opportunity.
