Frequently Asked Questions

How do I know what size battery I need?

We map your critical loads and how many days of backup you want, then size usable capacity to match. No guessing.

Can I add a battery to my existing solar system?

Usually yes. Many systems can add storage without replacing your panels. We confirm compatibility during the assessment.

What happens when the battery runs low?

The battery prioritizes your critical loads and, if the sun is up, your panels recharge it during the day to extend runtime.

Will my battery work in extreme heat or cold?

Quality batteries are rated for our climate and manage their own temperature. We install them where they perform best.

What maintenance does a battery need?

Very little. They are sealed and monitored through an app. We register the warranty and check in as part of service.
