Moonwatt Tech Stack

Sodium-ion battery storage systems for hybrid solar plants

Renewable Energy Equipment Manufacturing Amsterdam 11–50 employees Founded 2024 Privately Held

Moonwatt designs sodium-ion battery storage hardware and software for solar plants that need dispatchable power. The tech stack—C/C++, Go, MATLAB, PLECS, PSCAD, SCADA, Modbus, IEC 61850—reveals a company building real embedded-systems and grid-integration infrastructure, not just packaging commodity batteries. Active projects span power-plant controllers, grid-forming inverter control, BMS, and telemetry pipelines, while pain points center on real-world deployment reliability and utility-scale adoption—typical of hardware companies moving from prototype to field operations.

About Moonwatt

Moonwatt develops sodium-ion battery energy storage systems for hybrid solar installations in Europe. The company combines hardware design (inverters, battery management systems) with software (real-time control algorithms, grid-services software, OTA update infrastructure) to make solar generation dispatchable. Founded in Amsterdam in 2024, Moonwatt operates as a lean, engineering-forward organization (5 engineers, 1 lead, 1 finance, 1 sales) currently hiring in the Netherlands. The active project pipeline—power-plant controllers, grid-forming inverter development, telemetry integration—indicates early-stage commercialization of utility-scale storage assets.
