About

Founded in 2024, Moonwatt is a private headquartered in Diemen, Netherlands specializing in Solar, Energy Storage.

Moonwatt is a renewable energy storage startup founded in 2024 by a team of engineers with experience from Tesla and Freyr. The company manufactures Battery Energy Storage Systems (BESS) specifically engineered for solar hybridization, using advanced sodium-ion chemistry instead of lithium. The core technology features a modular string battery architecture with passive cooling, no moving parts, and DC-coupled integration that reduces conversion losses. The distributed architecture places energy capacity closer to generation sources, improving system resilience and reducing installation costs. Moonwatt targets both remote installations and utility-scale stations, addressing grid congestion and price cannibalization challenges facing large solar plants.
