Lunar Energy

Lunar Energy is a vertically integrated home-electrification platform developing advanced energy storage systems and software to power resilient, fully electric homes.

Designs, builds, and operates next-generation home energy systems for backup, resilience, and electrification

Lunar designs and engineers modular, whole-home energy storage technologies that simplify installation, reduce system costs, and improve customer experience. The company’s vertically integrated approach—spanning battery systems, power electronics, load control, and energy-management software—creates a unified platform that enables clean, reliable home power.

Rapidly rising electricity prices, worsening grid instability, and increasing outage frequency are driving demand for home energy resilience. Lunar’s system architecture, combining 20 kWh modular batteries, maximizers, and the Gridshare software platform, is designed to meet this accelerating need. Ground-up engineering enables higher efficiency and fewer components, reducing installer burden and lowering all-in costs for homeowners.

Access to reliable backup power is becoming foundational to home electrification. From seamless whole-home backup to grid-services participation, Lunar’s platform positions the company at the center of a rapidly expanding market as households transition toward clean, flexible, software-coordinated energy systems.
