Battery modes

Within the Lunar App, you can see your Lunar System’s settings and, depending on your installer, change those settings yourself. 

Your Lunar System will operate in a particular mode, which determines how it interacts with your solar, your household consumption, and the utility grid. These modes are described below.

Lunar AI

Lunar’s recommended mode.


This mode uses Lunar’s proprietary AI to maximize your cost savings and bill credits, as well as making use of your home-made energy.

Lunar AI will create an optimal control plan for your battery to follow each day, based on your rate plan and our predictions of your home’s unique energy patterns.

Backup 

This mode prioritizes using your Lunar System for grid outage support.Your battery will charge until it’s full and remain at 100%, ready for a grid outage. This mode may reduce your cost savings or utility bill credits.

Self-consumption 

Your battery will prioritize powering your home with your home-made energy. During the day, your battery will charge from any solar your home isn’t using. At night, your battery will power your home’s energy usage.

Time-of-use 

Your Lunar Battery will follow the same control plan each day, regardless of weather or your energy patterns. Currently, this mode is only settable by your installer.

Battery reserve

Your battery reserve is the proportion of your battery’s capacity that will always be saved for potential outages. If your battery reserve is set to 25%, this means your battery’s state of charge won’t go below 25% unless there’s an outage. The other 75% will operate in your chosen battery mode. 

You can find your battery reserve in the Lunar App by scrolling up on the home screen and tapping the battery mode card. Whether you can adjust your battery reserve will depend on your installer.
