What LumenHaus does
LumenHaus GmbH is a Düsseldorf-based residential energy company founded in 2024 that designs, manufactures, and sells an integrated home energy stack under the Sun product family: SunCatcher N-Type TOPCon solar panels, SunSaver all-in-one LiFePO4 battery storage (10–30 kWh modular, up to 12 kW output, 20 ms backup switchover), SunCharger EV chargers, SunHeater A+++ heat pumps, and the SunMini balcony storage system. All products are managed through the myLumenHaus app and a proprietary on-device AI layer (integrated edge AI chip with Smart-Eco mode) that optimizes solar self-consumption, dynamic-tariff arbitrage, EV charging schedules, and heating in real time, independent of cloud connectivity. The company operates a direct-to-consumer go-to-market: customers enter via the website's "Energiewende starten" funnel, receive personalized offers, and are handed off to a regional network of certified installation partners (Lumenators) operating under exclusive territory protection. Revenue is generated through hardware sales, a captive financing product (Freedom+ — up to €70,000, from 6.69% p.a., 1–25 year terms), a partner-branded dynamic electricity tariff (Dynamic+, with naturstrom), referral incentives (€400 per successful install), and brand-building sponsorships such as the Premium Partnership with Bayer 04 Leverkusen. The primary customer segment is German residential homeowners, supported by a secondary B2B channel of certified installer partners. The company is privately held, has 51–100 employees, and reports no external funding rounds in the available data.
