What Lunar Energy does
Lunar Energy is a US-based residential energy technology company founded in August 2020 by Kunal Girotra, formerly Head of Tesla Energy. The company develops, manufactures, and deploys an integrated home energy system combining proprietary hardware (Lunar Maximizers per-panel optimizers, a modular 10-30 kWh battery with integrated inverter, and the Lunar Bridge smart panel) with a proprietary AI optimization layer (Lunar AI) and a consumer-facing mobile app. In parallel, Lunar operates Gridshare, an enterprise grid-edge Distributed Energy Resource Management System (DERMS) that aggregates residential batteries, electric vehicles, thermostats, and hot water tanks into dispatchable Virtual Power Plants for utilities and grid operators across the United States, the United Kingdom, and Japan.
The technology stack centers on machine-learning-driven battery dispatch and household load forecasting, with the foundation laid through the 2022 acquisition of UK-based Moixa, which contributed the original GridShare software and a decade of optimization data covering approximately 150 million hours of real-world device control. Lunar AI creates daily energy plans for each home using utility rate structures, weather forecasts, and learned usage patterns, while Gridshare runs per-household and aggregate forecasting for Virtual Power Plant dispatch. The company holds UL 9540A 6th Edition certification on its modular DC energy storage system, and the Gridshare platform exposes a developer API for partner integration.
Lunar generates revenue through three principal streams. First, hardware sales of the Lunar System to homeowners directly and via installer partners (more than 40 installation partners) and channel agreements with Sunrun in the US. Second, subscription and software-as-a-service fees from utilities and partners for access to the Gridshare platform, with custom pricing based on connected device count and service scope. Third, grid services revenue from frequency regulation, demand response, and capacity market participation, monetized both through utility programs and direct Virtual Power Plant earnings paid to homeowners (averaging $464 per year per participant in California in 2025). Strategic investors and partners include Sunrun, SK Group, ITOCHU Corporation, Octopus Energy, and Honda, with total disclosed funding above $532 million and a $1 billion post-money valuation achieved in February 2026.

Lunar Energy product offering
Product offeringCore offering
Lunar Energy designs, manufactures, and sells integrated home battery systems (the Lunar System) consisting of solar maximizers, modular lithium-ion battery storage (10-30kWh), and a smart grid-connect panel, paired with proprietary AI energy optimization software. The company also operates the Gridshare enterprise software platform, a grid-edge Distributed Energy Resource Management System (DERMS) that aggregates residential batteries, EVs, thermostats, and hot water tanks into Virtual Power Plants for utilities and grid operators.
Product overview
Lunar Energy offers an integrated hardware and software platform for home energy management. The core product is the Lunar System — a complete home battery ecosystem comprising Lunar Maximizers (per-panel optimizers), Lunar Battery with integrated inverter stack (10-30kWh modular capacity), and Lunar Bridge (smart panel for grid connectivity). This hardware is paired with the Lunar App for homeowner monitoring and Lunar AI for autonomous energy optimization. For utilities and partners, Lunar offers the Gridshare enterprise software platform (a grid-edge DERMS) that aggregates residential DERs into Virtual Power Plants. The company also acquired Moixa's GridShare software in 2022, which added machine learning optimization capabilities. The platform supports multiple device types including batteries, EVs, thermostats, and hot water tanks, with deployments across the US, UK, and Japan.
