I now have four PVs on my garage roof and am going to wire them up today in parallel. (I had one PV in place already with two batteries. I now have four batteries, so the one 100W panel is doing all the heavy lifting.)
As the one PV was already in place with its own hole, we drilled another hole for the three new panels.
I have read that the MC4 connectors are weatherproof. But how about the branch connectors? Should I run the wires into the garage and attach the branch connectors there, or should it be done on the roof?
