Meet the
Lunar System

Outlast outages with the Lunar Battery

Big battery, big backup

With 20 kWh of battery capacity, the Lunar System provides more energy for longer outage protection. It’s the new standard to handle your home’s growing energy needs.

Power through storms

Lunar tracks severe weather to prepare your home for an outage. If your home is in the path of a storm, the Weather Watch feature will fully charge your battery and leave it there until the storm passes.

Outage intelligence

When the grid’s out, the Lunar System steps in. You’ll have seamless backup power and real-time data on how long that power will last. At every sunrise, the battery will recharge again and again.

Save money and make money — effortlessly

Energy plans as unique as your home

No two homes are alike — and with Lunar AI, neither are their energy plans. Every day, Lunar makes a unique plan to maximize energy savings. It monitors the weather, tracks energy spikes such as when you charge your EV, and uses this data to design a personalized, daily plan.

Savings made simple with Lunar AI

In California, there are 288 different energy export rates every year for homes with solar. With Lunar AI, you’ll never have to worry about a single one. Lunar AI keeps on top of rapidly changing energy prices to optimize and automate your system to reduce your bills.

Send your power company a bill 
for once

Power companies in California and around the world pay homes for extra energy when it’s needed the most through Virtual Power Plant programs. Enrolling in these programs is a snap in the Lunar App.

The power couple.

Solar and battery, designed to work together.

Meet the all new, all-in-one Lunar System. It is stunningly compact, including everything you need to capture more clean energy and power everything in your home.

Just add solar panels to make, use, store and control your own energy—day and night, foul weather or fair.

Beauty. And beast.

Powerful performance that’s wall-worthy.

It’s what happens when great designers and great engineers work together toward a single ambitious goal.

Its compact size makes the smallest demands of your wall space. And as your percentage of solar power goes up, your energy costs go down, down, down.

Our industrial design was recognized by
the international iF Design Award jury.

Tried. Tested. True.

Designed to go all out, all the time.

The Lunar System is built for the world as it is: an environment of increasing extremes.

We put every part of the system through a series of brutal tests — hot or cold or wet or dry. It’s the best-engineered response to the worst possible conditions.
