What to Look For in a Battery Enclosure for Solar Systems
~ Okay, so you've made the jump towards utilizing solar, but now what? An important next step in utilizing solar effectively for your business is to choose the system you need and the proper method to protect it.
What is a Battery Enclosure?
A battery enclosure is a box designed to protect batteries from potential weather and battery mishaps. They can be designed for indoor or outdoor use, and may include room for electronics. Specific designs allow for pole, wall, or ground mounted systems.
Why Do I Need One?
Battery enclosures are essential components of off-grid solar systems for a number of reasons including: physical protection from outside elements including people and weather patterns, maintaining consistent temperatures, and meeting the requirements of the National Electric Manufacturer's Association (NEMA).
Which Type is Right for Me?
The specific type of battery enclosure design is different given the application and requirements of the project. The features and functions differ depending on the location and needs of the system. In general, all battery enclosures should be vented. This includes VRLA batteries, as hydrogen gas could potentially build up in a fault condition (e.g. controller failure). Passive venting should be adequate and active venting, like a fan, should only be required in rare cases. NEMA provides a rating scheme for consumers to easily decipher the correct number associated with his/her needs.
