The system is built to stringent quality standards, ensuring long-term reliability.
Lunar Energy was founded by a former Tesla Energy executive with a mission to electrify homes through integrated battery and solar systems.
The company has expanded its global presence across the US, UK, and Japan.
The Lunar System combines modular batteries, hybrid inverter, smart panel, and panel-level maximizers into an easy-to-install home energy ecosystem.
The AI-driven Gridshare software (acquired via Moixa) intelligently manages energy usage and enables participation in virtual power plants.
The system delivers reliable backup even in extreme conditions like flooding and seismic events.
Strategic partnerships include integration with Eaton smart breakers and collaboration with Sunrun on virtual power plant deployments.
Lunar’s network of connected systems empowers homeowners and supports grid resilience by aggregating distributed energy resources.
