Hello,
This is my first post and I'm just recently getting started in researching these things so thanks for your patience.
I'm working on building a system using the MPP Solar LV2424 and a 24v 200Ah Lithium battery. I'm trying to get the wire sizes correct because I don't want to cry over my final copper costs. I was reading through Will's book and I was wondering if I should size my wire based on the 80a charge controller in the device, or on the 2.4kw inverter? I'm sure it should be the inverter but I wanted to check with people smarter than me. The manual says 1*4AWG. Is that 1x4, 1to4...
Secondly, The typical amperage is 100A, should my bolt on fuse be based on this number and size up to 150A?
Lastly, The manual also states that PV cable size should be 6AWG. Almost all the MC4 lines I've seen are 10AWG. I've seen some 8 as well. Am I misinterpreting something or is this not really an issue? If you need this info, I plan on running six 240w panels. The configuration I've chosen currently should produce around 74w and 24A. I don't have the panel info with me right now for exact numbers. the configuration may change later.
Thanks in advance. I look forward to being more active here.
