It is NOT connected to the A/C panel or anything. With that though, I have a regular 1000W (2000w Peak) inverter with a 240v receptacle on it. That's a great idea to mount directly to the inverter. Then from the MPPT to the battery will be approx 600mm. The distance from panels to MPPT will be slightly over 7.5meters. I've got multiple tabs open so i can cross reference constantly. There seems to be soooo many different ways of saying a size of cable it's driving me nutso. Wire terminal/tab sizing impinges on all that stuff too. Wherever you're getting your A ratings on wire should also cover the length, and vary to suit.ĭon't overlook fusing/breakers/isolators on your wiring either. If you already have a spool of 6AWG (13mm) you could carefully trim back at the ends to fit, but really. The distance should be short, and if the mppt is mounted right next to an inverter, even shorter wired to the inverter batt terminals, which are likely MUCH bigger wire.

The gen-u-ine solar wire is nice to work with, and a pro installer would set you sweet with 6mm2 in virtually all cases. For long runs, combine to a bigger wire or run 2 pairs. This depends on distance of course, but it's likely you could use 6mm2 wire to the mppt safely even with a single pair. They'll need wiring in parallel into a 100/ mppt, and presumably use MC4 connectors, which are 4 to 6 mm2 wire suitable. Best to ask if confused, you're going well so far. Looking forward to any and all advice, help. I apologize if this sounds a little long winded or confusing.probably because I am confused! haha. Im new to it all but the brain cells are firing on all cylinders, but I could be completely off the rails with it all.

I know there are losses here and there, but it will still be way above the max current rating of 37amps for the MPPT's max wire receptacle size of 6AWG.įeel free to blow my limited knowledge of all this out of the water. The panels are approx 650w together, divided by 12v = 54.17amps potentially coming out of the 100/50 MPPT to the batteries. When the MPPT uses the extra voltage to create more charging amps, the amps can spike considerably on the MPPT output side to the batteries. From my research, that can be a problem given the panels statistics. The 100/50 MPPT can only accept up to 6AWG (37amp wire). My biggest concern is wiring size from the controller to the batteries. 6AWG is good for 37amps effective use current, so that should be more than enough for the approx 20' fun from the panels to the controller (i'm open to other suggestions on wire size if you have advice). I will use 6AWG from the panels to the Victron 100/50 smart solar controller which will be within 3' of the batteries. The output of these panels is shown in the image below: I have 2x Sunpower E-20 327w solar panels that i'm going to install.
