Susitna Energy Systems


Batteries store the energy that is generated from an off-grid system for real time consumption or for a power failure on a grid-tied with battery backup system. Batteries for these systems are deep cycle lead-acid, meaning they are regularly deeply discharged, and can be either flooded (“wet”) or valve-regulated (“sealed”). Flooded batteries are ideal for full time residences, as they are usually less expensive than sealed batteries and require regular maintenance, but with proper maintenance they can last a longer lifespan. Sealed batteries are best for minimal interaction situations where they require little to no maintenance.
