Recommended Power Inverter, 50 Amp Transfer Switch and Charger For Solar Upgrade On RV Camper

Updated 07/25/2021 | Published 07/22/2021

Question:

I am installing 4 - 100 W solar panels on my 5th wheel with a 3000 W inverter. My shore power is 50 amp. I want to install a 50 amp auto transfer switch to switch in order to switch from solar to shore power. I also plan to install a 30 amp fuse between the Xfer switch and sub panel. The wiring diagram on the Xfer Switch shows the load from both sides being joined together. From what I see on the pictures, it looks like I dont have to do that. I want to keep the 240 v 50 amp line in to go to the RV power distribution from the load side and the Inverted Solar power to go to its respective the load side. Can the Loads be isolated from both Line sources?

I recommend using the Go Power Industrial Pure Sine Wave Inverter Charger # 34275013. This will reduce all the components into one system by combining your transfer switch inverter and converter/charger into one unit. You will be able to wire in your 50 amp circuit with this unit. This will mean less wiring and space required for your setup and only one panel to monitor everything in your system.

On a 50 amp RV circuit you have 2 separate 120 volt holt circuits that feed into the RV. The hot lines stay separate to the panel. They share a common neutral wire which is why you see it rated for 240 volt. The 120v loads will stay separate.
