Deep Cycle Battery Banks 101

The battery bank is one of the most complicated and costly components of any off-grid power system.

Your battery storage needs to be large enough to supply power year-round. Nothing is more frustrating than suffering a power outage because your battery bank doesn’t store enough charge.

On the other hand, too much battery capacity means your system won’t be able to fully recharge. If your battery bank is too large, your batteries can’t get the full charge, which can ruin the batteries.

Dialing in on the right battery bank is an important step to designing your off-grid system. You want to make sure you hit the sweet spot.

What’s in a Battery Bank?

A battery bank can be composed of a single battery, or multiple interconnected batteries that are wired to work as one large battery at a certain voltage and amp-hour capacity.

We design our battery banks to pair with our off-grid systems. They include some extra components to ensure the system works out of the box.
