You guys are smart, lots of times smart, thrifty, but safe go hand in hand. I'm going to spend quite a bit on wire, etc connection gear. What brands and websites do you guys look at mostly, hopefully without expensive shipping, and maybe free shipping esp with large purchases. I just dont want to get cheap ebay junk. That said , if you know a seller or have a link to good quality ebay stuff let me know. I'm planning my build in May so China distributors are okay also. This will be for an off grid cabin, but I would like listed stuff or quality close to it like Canadian listed or something. I'm not sure where to save money that doesn't get me junk.I have the PV wire already and MC4 connecters I got with my panels from Santan. I also have inverters and charge controllers.
1.) Thick welding wire from batteries to inverter. I'm think go as big as possible. I have two 48v 6kw inverters that will be split phase 240v on the house side.
2.) At least 20 Terminals tinned would be best if its a big savings I can apply dielectric grease over good copper terminals. Location is a solar shed in the desert.
3.) Midnight solar combiner boxes for 50 panels with the outer disco switch on each box
4.) Midnight solar breakers for disco boxes. I dont want to do MC4 fuses/branches.
5.) Bus bars - I have a drill press and could use starboard to mount/make a bus bar from solid copper. If I cant het tinned I could grease it up with dielectric grease to prevent corrosion, esp galvanic corrosion between the stainless bolts and the copper.
6.) Class T fuses at the batteries
7.) Should probably have a big emergency DC disco box outside of the solar shed before the controllers inside.
8.) Should I put a disco between the controller and batteries? With 16s2p 48v I'm not sure if a regular blue seas battery switch would work with a battery that big.
8.) I'm thinking regular home depot wire in conduit from the combiner boxes to the solar shed. Same from the inverters to the cabin.
