If you're using batteries with your off-grid system, you will need to protect them from the elements and separated from living areas. Often that means a dedicated enclosure. We supply various sizes of enclosures for holding batteries and associated electronics. Our most popular metal battery boxes are the NEMA 3R (rainproof), mill finish aluminum boxes, which can hold from a single battery up to 6, 8, or 10 if pad mounted. Many standard mill finish aluminum metal battery boxes are in stock, ready to ship.
