In reply to Edward A McGilly. Hi Edward, Have you seen our solar, 12volt and 120volt posts? We have wiring diagrams and wire size recommendations that can be adapted to your use. Blackwater, gray and fresh water pumps normally run off of 12v since they are purpose built for RVs/Vans/Boats. A 13.5k Btu AC is very large load, it probably uses 1500 watts or so? Unless you plan a very large inverter, battery bank and solar you will have a hard time keeping up with that load. If you need AC you may want to consider a generator or shore power hookup. Depending where you are located a lot of us get by with a roof mounted fan. which used a fraction of the energy of a AC unit. -Andy

I understand the electrical wiring from the 300 Watt solar panels, 1 is 100 watt the other is a 200 watt panel. That go to the converter then the inverter and batteries. There are 2 all totaling 40 Amps. Where do I get a proper diagram of the wiring of these devices? this should include wire size #4 to each major component then # 6 wire to the rest. The back up circuit from the main van battery will feed the auxiliary circuit.
What size wire is used for this. I understand that fuse protector and on and off switches are to be used for all major components in the power start up device. D.C. fused circuit board is for 12 lighting, outlets and A. C. from the inverter is a transformer that increases the voltage to 120 V power. This will allow A.C. volts to run appliance, pumps for Black water, sink white water and gray for dish water. If I’m not correct please inform me of the proper voltage for a particular item that I have mentioned. Last is 40 amps strong enough to carry the load for an air conditioning unit at 13500 BTU plus keep the D.C. supply to carry it’s load?
