Decided to go with 12V system, but i think i pushed it to the max. I am a new to this. i figured out that i needed a total of 2300W to power my devices, so i settled on a 12V 3000W inverter,, but then i came across a deal on the lifepo4 batteries, where the cost was extremely low compared similar batteries I was looking at. So in my excitement i brought three lifepo4 batteries. Now im stuck with them and i now think i messed up. These aren't 12V 100ah batteries that i see everyone going with, these are three 12V 300ah 200A BMS lifepo4 batteries. So my system is actually a 12V 900ah 200A BMS solar generator system. I found a 80A MPPT controller that can handle 1,200W of solar. I got the wiring down as, i split the system into two legs. So instead of having wires that are carrying 613A, I have one leg that is 350A (Inverter) and the other leg that is 300A. (MPPT, Fuse Box, 60A AC/DC Charger). So now i am having a problem with how to ground. From what i gather i have to ground my 1,200W solar array with an 8' grounding rod that is then tied to the main service grid ground rod {is that right?). Now on the other side of my system, which is on wheels and can be disconnected and packed up fairly easily for transport This is what is bothering me now. Since it is not connected to the house electrical system (may in the future) do i ground it or not? With it being a 12V system and NEC 250 saying I don't have to ground anything that is below 60 Volts, yet i wanted the extra safety feature of grounding especially when hooked up to the solar array. So do i then connect the grounding screws on the inverter and the MPPT to a grounding busbar, then run it to the negative battery busbar to create my ground that way? or do i just not bother with grounding my devices at all? Also, if i decide to ground this side when it is hooked up to solar should I attach the MPPT and Inverter to a ground busbar, then tie it directly to either the PV solar grounding rod (which is connected to the grid grounding rod) or do i attach it directly to the grid ground rod? I am kinda stuck on what to do, so I can move forward.
