Been working on the power system design (a bit of discussion HERE) and have started to order "stuff." This is a (very small) representation of what I'm planning on. This layout gives me shore power and Generator (through an auto transfer switch) to feed the Victron Multiplus 2 3000VA 120v Inverter/Charger. I've included a 30 amp DC-DC charger to run off the starter battery and charge my lithium pack when the motive engine is running. I will be replacing the old "squareD" residential style breaker box with one from progressive dynamics that is set up to have two feeds. The Inverter/charger I picked has two AC outputs. One is pass through only, and will only power items on that branch when plugged into shore power (like the AC units). The other branch will supply inverted AC from the batteries. Speaking of Batteries, I decided on 400 AmpHours (4x 100 amp hours) from Epoch. They have gotten VERY good reviews everywhere I've looked and they are relatively inexpensive for a heated LiFePO battery (about $500 each). They have their own BMS. This system also gives me room to add solar in the future. Based on my energy budget the set-up should give me just over a Day of runtime (350 amp hours with a 20% overage calculated in and a 20% SOC) if we are pretty wasteful with our energy consumption. The charger puts out 120 amps, so we should be able to run the gen for 3 hours and be fully charged again.
I'm very happy with how this has worked out. I aimed for a 5000 dollar budget and I will go over that by about 10%, but it will be a VERY nice system when complete. I will be placing the orders for my Victron stuff soon. Once I have it all in my hands, I'll work on the layout and order my battery cable and terminals. Something else not shown, and kind of the budget buster, is the Cerbo GX monitor system I will include. The Cerbo will replace the OE control panel in the coach. It will display all the battery information, control my inverter, display up to 4 tank levels (with a couple add ons), it can send an auto start signal to the genset, if I so desire, etc. Very neat and it displays all the information on a 5 or 7 inch screen (like a small tablet).
Now that I have this stuff figured out, I will get back to work on cleaning the rest of the interior, running my new lighting circuits, etc.
