I have an EVO T2050 RV which has a Dometic 2 way refrigerator (110volt and Gas).
Due to Australian road laws the refrigerator cannot be used with gas while traveling so I bought a 12v to 110v inverter to overcome this.
I fitted a three way switch to swap the power between the mains (Australia only has 240v A/C mains power but using a step down inverter it outputs 110v) or the 12v battery. The three way switch prevents me inadvertently having the battery and mains electric on at the same time. (The third option which is positioned between the main and 12volt is a null/dead setting.)
The battery on the RV is located at the front of the caravan with the associated 12v cables running the full length of the caravan into the main switch/fuse boxes.
Could anyone advise if I can split the battery cables at the back of the caravan and run two separate leads for the 12v/110v inverter (which is close to the other electrical bits) rather than run a separate cable from the battery at the front?
When the caravan is connected to a mains power the electrical equipment sends a charge to the battery, I guess similar to what a battery charger would do.
My concerns are that once connected to the mains will the electrical equipment when sending a charge to the battery also feed power to the 12v/110v inverter? and if so would this be an issue and possibly damage the equipment?
The three-way switch, that I have installed, controls where the power source for the fridge is coming from. So should I switch off the 12v/110v inverter before switching over to the mains 110v option? and by switching the inverter off will there be any issues?
I hope I have made myself clear and if necessary I have drawn a schematics’ plan if anyone would like to see how I have arranged my 12volt power.
