I currently have a travel trailer that has 100w of solar and 2 64ah AGM batteries. I am updating this to a total of 400w of solar and 300ah of lifep04. There is existing wiring for the solar panels/charge controller, brake-away switch, and the 12v system in the rv. I will be adding: a shunt, disconnect, 12v fuse block (for adding new 12v appliances) and 2000w inverter. Can you please let me know if you have any feedback on the plan below. The items outlined in green are the existing items in the RV.
