This client elected to go with a Refrigerator Vent Combiner Box instead of our usual Roof Combiner Box because they didn’t want to have another hole drilled into their roof. The Refer Vent Box utilizes the existing hole that is used to vent the refrigerator, but it can only accommodate up to four solar inputs. It’s not a bad option if you’re definitely not going to expand, but it is obviously limited. The Roof Combiner Box we manufacture allows for eight solar inputs, doubling the possible capacity.
