Please contact us if you have any questions about what size combiner box and breakers you need for your particular panels. This is a very important part of your solar array. The combiner box takes the multiple parallel strings from your solar panels and runs them through a DC circuit breaker before landing these parallel connections on a common busbar. For the common + and - busbars, you can use a smaller gauge wire in conduit to complete the wire run from your array back to the charge controller and battery - which is probably a good distance away.
These powder-coated aluminum, rainproof array combiners will accept DIN-rail mounted 150v circuit breakers, MidNite 300VDC breakers, or 600VDC fuse holders for grid-tie arrays. A plastic cover provides a dead front for safety and can be knocked out for either breakers or fuse holders. Both a negative busbar and ground bar are included. The aluminum NEMA 3R enclosures are approved to be mounted at angles from 90 to 14 degrees (14 degrees = 3/12 slope). ETL Listed to UL 1741 for the U.S. and Canada. Breakers and fuse holders are not included. See Electrical Distribution Parts section for breakers, fuses and fuse holders.
A brighter future. Off the grid. Iron Edison battery systems can be used for 12, 24 and 48 volt applications. We can also help you optimize battery capacity to take better advantage of the solar, wind and other hardware you may already have in place.
