Batteries and inverters need to be installed as close as possible to each other because of the high currents and large wire sizes used. If flooded lead-acid batteries are used, off-gassing must be considered. Fumes that come from batteries are corrosive and will damage equipment, so battery enclosures must be vented to the outside. Our enclosures facilitate DC connections and connections to inverters/chargers by providing DC circuit breakers for the power inverter and solar charge controller as well as AC connection points for inverters (busbars for input from generator and output to AC distribution panel). These enclosures also facilitate ground fault protection for the solar PV array for code compliance on roof-mounted arrays. Be sure to order the correct GFI breaker for your system. For help choosing the right electrical enclosure, our Tech Desk is available to help at 800-919-2400.
One more thing: Most of our electrical enclosures are built to accommodate specific inverters, so decide on your inverter before shopping for its enclosure...or simplify everything with a pre-wired solar inverter that includes an enclosure and other common accessories - already fully wired together and ready for easy installation!
