In general, most household solar panel setups do not need a solar combiner box. Solar combiner boxes are required for those that have more than three solar panels in a system. You need a combiner box when your photovoltaic system has more than three strings, systems with three or fewer strings can connect directly to. . Do I need a PV combiner box? I'm getting ready to remove all of the Enphase Iq7+ micro inverters on my 48- LG360N1C-N5 panels and hook them into my EG4 18kpv. In this article, I will. . Is it safe to connect these 4 panels in parallel without going through a combiner box? I intend to put a fuse between the panels and the charge controller, also a fuse between the controller and battery bank, and another between battery bank and inverter. It is used in PV (photovoltaic) systems, and usually contains fuses or circuit breakers to protect the system from over-current conditions.
