Today is the 4th of January, nearly all my components are here, I am still waiting on the battery disconnect switch which I would like to have before I commit to the location of my DC power bus (Lynx). In an effort to document, I have updated some of the TripleE (Leisure Travel Vans) documentation to reflect my changes. I have also found an error in one of the diagrams, I sent an email to EEE to verify, but I have not seen an answer.
My updated 12V DC wiring diagram.
In looking at the AC side, I came across a transfer switch under one of the galley drawers.
After some research I figured out what it is and I think it is pretty ingenious. A typical RV has a 30A shore power. Using multiple high load appliances can easily exceed the 30A. For example, you arrive at your site and turn on the AC (15Amps), the electric water heater (15Amps) and then throw something in the microwave (15Amps). Turn on some lights, etc and it is easy to get over the 30A. The way EEE tried to mitigate this is by putting the water heater and the microwave on a single 15A breaker. The breaker feeds the transfer switch which provides power to both devices until the microwave demands a large load, it then will shed (pause) the water heater load until the microwave finishes. This allows running two high load devices from a single breaker and minimizes the probability of tripping the main 30A breaker.
The above does present a quandary for me. I want to power the microwave from the Inverter, and it is fed by the same breaker in the panel as the electric water heater. Since the water heater can also run on propane, I might want separate the two. I am thinking at this time to not change it since there is a switch that controls how to heat your water, with electric or propane. We will just have to remember to not use the water heater in electric mode when using the inverter. If it becomes a problem, I can rewire it later.
I have figured out how to power all 110 circuits from the Inverter. Previously EEE had fed a single circuit of limited receptacles directly off the inverter, that was it, no AC, Microwave, water heater or the other remaining receptacles in the RV. I was able to pull the feed of this circuit back from where it connected to the inverter to the compartment under the dinette seat and there is sufficient wire to connect this directly into the Distribution panel. I will just have to add a breaker for it.
This is the AC IN and Out pulled back up into the compartment under the dinette. I will feed the circuits formally fed by the inverter directly from the distribution panel and I will replace the AC IN wire with 10/3 wire since it needs to support 30A.
I have decided that I will locate the Inverter in the same location as the old one. This is a picture of the old, 1200W, inverter.
The new inverter is bigger and will make more heat so I wanted to improve the ventilation of the compartment.
This entry is already too long, so I will stop here. When I get the disconnect switch, I will start installing components.
