Hi,
I am gathering materials to complete a 120v off grid solar system for my small cabin and have many questions that I hope the community can help with. I worked with Lori at practical preppers and got as much as I could they had to offer for my setup.
My system will comprise of 3 EG4 LL 48v batteries in the EG4 rack, the EG4 6500 (which has yet to ship,) and two strings of 6 panels in series.
My first question is regarding the connection of the 4/0 AWG from battery rack to the 60v 200 amp breaker (They sent two breakers but dont I only need one for the + line right?) There is no way this 4/0 is going to fit in the mechanical lug. I am thinking about removing the mechanical lug on the breaker and connecting directly the 3/8 lug that is on it by the screw and nut with a bigger one and torquing it down. Is that fine to do?
2nd option would be to run the 4/0 to a busbar and 2/0 into the nader...I need to buy some 2/0 to go from the breaker to the inverter anyway. Which option would you go with?
