I have three REC330 panels mounted in series on the roof of my shed: 990 watts, 10 amps, 123 VOC. The wiring terminates in a Midnight combiner box with a 15 amp disconnect. I also have a Bluetti AC300 with B300 battery in my house for emergency backup power. I'm wanting to move the Bluetti into the shed and set it up to receive the input from the solar panels. The solar input cable supplied from Bluetti is an aviation terminal that connects to the AC300 and the other end are two pairs of MC4 connectors. These are labeled DC1 and DC2. Each input can handle up to 1200 watts, 12 amps and 150 VOC. But I will only use one pair of them. The solar panels are protected with a lightening arrestor, grounded and bonded to a ground rod.
My questions are what type and size of cable shall I use to pull from the combiner box (open wire ends) to the MC4 terminals? What brand of cables would you recommend?
