{"title":"MC4 Adaptors","description":"\u003cp\u003eAn adaptor lets two panels share one lead down the roof.\u003c\/p\u003e\u003cp\u003eTwo panels means two pairs of MC4 leads, and without an adaptor that is two runs to the regulator, two holes in the roof, two glands and twice the cable. A two-to-one branch joins the positives to one positive and the negatives to one negative before the cable leaves the roof, and the whole array comes down as one pair. A three-to-one does the same for three.\u003c\/p\u003e\u003cp\u003eThat is a parallel connection, and it suits panels of the same voltage. The voltage stays the same, the current adds, and the regulator sees one bigger panel. Check that the regulator and the cable are rated for the combined current before joining, because the branch does not reduce it, it concentrates it.\u003c\/p\u003e\u003cp\u003eFuse holders and fuses for the MC4 line sit in the same collection, because a paralleled array is exactly the array that needs one. A fault on one panel in a set of three has the other two feeding it, and the fuse in each string is what stops that.\u003c\/p\u003e\u003cp\u003eEverything here uses the same locking, polarised connector, so nothing goes together backwards.\u003c\/p\u003e","products":[{"product_id":"roam-gear-solar-mc4-2-to-1-adaptors-pair","title":"Roam Gear Solar MC4 2-to-1 Adaptors (Pair)","description":"\u003cp\u003eFor joining two solar panels in parallel into one MC4 lead.
