Lunar Energy unveils 300 kWh battery stack and bidirectional EV charger

Lunar Energy has announced the launch of its next-generation Lunar System battery and a new bidirectional EV charger. According to the company, the new Lunar System consists of 5 kWh battery blocks situated under a hybrid inverter module.

A single stack of the new system utilizes six blocks to achieve a total capacity of 30 kWh.

System Specifications and Capacity

The new hybrid inverter raises continuous power output from 9.6 kW to 13.4 kW and increases motor-starting current from 134 LRA to 185 LRA.

Specification	Previous Model	New Lunar System
Continuous Power Output	9.6 kW	13.4 kW
Motor-Starting Current	134 LRA	185 LRA

Ten 30 kWh stacks can operate together to provide 300 kWh of total storage and 134 kW of continuous power. For larger installations, Lunar Energy offers a pad-mounted configuration capable of up to 1 MWh, though specific technical details for this setup were not disclosed.

Bidirectional EV Charger Details

The new bidirectional charger delivers up to 25 kW of power, adding 100 miles of range to an electric vehicle in one hour.

Lunar Energy manufactures these units at assembly facilities in Washington and Georgia. The company’s engineering and research and development teams are based in Mountain View, California.

Executive Commentary and Software

• Kunal Girotra, founder and CEO of Lunar Energy, remarked, As grid demand surges at an unprecedented pace, households and enterprises are experiencing the burden via higher costs and frequent service interruptions.
• Girotra continued, This updated Lunar System pushes the limits of smart energy automation by incorporating the EV, allowing commercial entities to command their own energy usage.
• Sam Wevers, Lunar Energy’s product director, declared, Lunar Energy’s bidirectional EV charger stands alone in its ability to leverage the EV’s battery as a smart energy asset working in tandem with the rest of the residence.
• Wevers observed, Automating rapid charge and discharge cycles using solar, storage, and low-cost grid electricity can drastically lower the expense of powering your vehicle.
• Lunar’s proprietary AI software powers the system.
• The firm distinguishes this AI-driven software optimization from basic scheduling tools.

Operational Modes and Grid Integration

The new hybrid inverter connects to new or existing solar arrays or operates as a standalone battery system. Lunar Energy states this setup could generate revenue as grid-support programs for bidirectional EVs become available. The company asserts its AI-customized software optimizes stored energy value on a house-by-house basis, saving customers more money than solutions relying on simple scheduling software.

What to watch

Lunar Energy plans to begin Lunar System installations in early 2027. The bidirectional EV charger will follow with a rollout later in the same year. Tracking the timing of these two distinct launches will show how the company sequences its hardware availability, separating the initial battery stack deployment from the subsequent release of the vehicle charging unit.
