Hello everyone! I can't seem to find a good diagram on the web illustrating what it is that I hope to achieve. I'm looking to have a 50 amp shore power inlet running to a 50 amp auto transfer switch which will also have a 2000w inverter coming in. This box will run to a 60 amp distribution panel which has both ac/dc breakers and fuses. Ill have four 180w mono pv panels running to a charger controller which will run to the inverter and the distribution panel.The 60 amp panel I've found also is a smart battery charger. 6 6v deep cycle batteries will be the intended bank, which will have an isolator hooked up from the alternator. Please tell me if there are any flaws or if I am missing something.

I rearranged your requirements a bit. Only thing missing is "What's your draw?"

Lol thanks, my bus mimics my writing abilities.

Daily draw will be 200ah per 24hrs

No, not ripping on you, I'm making a checklist.

I'm in a sorta similar design phase-electrical-, but have much of the hard part done. My bus came w/ 10K Onan genny and 100amp 220 V shore power, all wired correctly (gauge/flex conduit) with manual transfer switch.

Why auto transfer switch? vs manual?

I need to also incorporate Solar and 6v battery bank. like you, so that's why I'm unknowledgably chiming in.

I've heard you don't want to discharge your batteries more than 50%.

Now sit back and wait for the smart people to talk.

You guys are fairly similar to the system I am currently testing. One question tho....Why use a separate auto xfer switch? They not cheap. In my set up, I went from my shore power inlet, to a 3000W/ 6000W Inverter/ Charger. It has the xfer switch built in. From the inverter/ charger it goes to a Progressive Dynamics Fuse Center (NOT the converter/ charger type). Of course i do have fuses at battery bank and inverter/ charger, and will use a surge protector (RV style) at the shore power/ generator(whichever is avail). For Solar i went with the Midnight Classic. There seem to be a few ppl on this site that give rather exceptional info. I personally am an ex aviation electrical tech from the Navy, so feel free to PM or ask here.

When I 1st started this whole journey, I was going to build out an enclosed trailer. But have decided I rather have the ability to tow other things while camping. Which led me to this site. I still use tnttt.com tho. It has some great people and info for everything relevant here minus the drivetrain. When designing the electrical system, I looked at the transfer switches, and converter units(120ac to 12dc) but decided an RV style Inverter/ Charger simplified the setup and lowered the cost greatly. I purchased an AIMs 3000W continuous/ 6000W peak pure sinewave Inverter/ Charger with built in xfer switch from walmart.com and had it shipped to local store. Aprox $825. That gives you: programmable 3 stage 100amp charger(prog for dif battery types), 3000-6000W pure sinewave inverter, transfer switch that switches between inverter and shore automatically(if on shore power it will pass thru power to run equipment plus use remaining power to continue charging batteries), a nice remote panel to control unit, and auto generator start when batteries reach a programed limit(mine set to start genny when batteries get to 60%). It simplified the wiring without the need of additional xfer switches. Now due to the amount of current draw, it does require installation to be fairly close to the battery bank. Less than 5 feet. But when you have to use 00awg cable, shorter is cheaper For solar I went with 4 LG 255 mono panels, and Midnight Classic MPPT charger. Storing all this electrical goodness are 8 Duracell GC2s rated at 215ah each. Giving me a total of 860ah. In testing this allows me to run an LG 5500btu window shaker unit for 2.8 hours before generator kicks on for the 60% limit i set. At 50% I can get it to just to 3 hours and change. That is while also running a Dometic 120/12 fridge continuous. I chose to design the system this way so EVERYTHING is usable on Battery(inverter) on shore(charger 12v and pass thru ac 120v), and generator(charger 12v and pass thru ac 120v). Some people prefer a simpler design with multiple inverters (smaller ones for dif devices) so they can turn off those not needed to prevent phantom drain as all inverters waste some power to heat during the inverter process. But during my tests I have determined it is not enough to worry about. Between the 1Kwtt+ of solar, shore power, generator, and alternator with battery isolator I should be fine. But my plans are for a Shuttle Bus, or 7x16 trailer. A full size Bus would require more panels, 2nd charge controller, more batteries, and next size up inverter/ charger (5000w/10000W). Other items used are 00awg power cable, 4awg power cable, Progressive Dynamics Fuse/ Circuit Breaker Panel, 500AMP fuse blocks and fuses, and my 3000W Inverter Generator. This system has been running flawlessly for a couple weeks now for testing. I have yet to find the perfect vehicle for it, but am closing in I hope.

Thanks for adding details of your system. Do you have a price breakdown or suggestion for sources for components?

Thanks !
