400 watt 12v solar generator
Hello I need help. I recently bought four renogy 100 watt 12v solar panels so a total of 400 watt 12v. Charge control 40 amp MPPT rover with bluetooth adapter. 2 renogy 12v 100ah gell battery. 2000 watt inverter. My main goal is to setup a solar generator to power normal appliances such as mini RV fridge, microwave etc. Normal setup for offgrid living. 1-What is the best way to wire the panels and why? In parallel or series for charging 12v 100ah gell batteries. 2- Charge controller 40amp rover terminal holes accept max wire gauge is 8 awg does that mean it can fit 8awg and less example 10,12,14? It will not fit 6 awg which is bigger then 8awg? 3- I want to be able to charge a 12v battery take it off and charge another one. When doing so do I take off the panels or battery first ? What's the safest method of dismantelling the system ? Take off panel first from charge controller or take off battery ? 4- most setup I seen is panels in series. Then setup for battery would be parallel. Is this this the best method for my application? 5- should I just use 8awg or 10awg for the whole setup? I dont want to waste money on buying differnt wires. 6- panels 400 watt 12v panels to charge controller has a 40amp breaker. Charge controller to battery have a 40amp breaker and battery to 2000 watt inverter has a 250amp breaker. Is that good enough for protection? Sorry for so much questions please help.
