Updated – July 20th, 2022: Updated wiring diagram and parts list for my buddy Al to reference on his trailer upgrades
Thanks to Explorist.life – Great website to learn about solar and power for RVing. Although I used many different wiring diagrams and tutorial videos, this is the base package I started with.
In October 2021, I added 600 watts (6 x 100watt Renogy Solar Panels). The panels are wired in sets of 2 using the Airstream prewire ports on the roof. I used a Victron 150volt/60am solar controller to convert the solar power into battery power. I mounted the panels using AM Solar Brackets which are quite expensive, but highly worth it. They use 3M VHB tape to attach to the roof with no holes. I also purchased extension bars so I can tilt the panels 45 degrees to get better sun.
Battery and Inverter Upgrade
We doubled our battery capacity to 400Ah by adding 2 more Battle Born Lithium Batteries. I moved them from the battery box behind the propane tanks, to under the bed. I also upgraded from the 1000watt standard inverter to a 3000watt hybrid Inverter charger also mounted under the bed. We now have enough battery power and inverting capacity to to “Off Grid” for extended time. I also added a Smart Shut to monitor the Battery Capasity, Smart Dongle to interface to the Inverter and a Cerbo GX monitor and Cerbo Touch 50 touchscreen to see what is going on.
