It's highly recommended to have some way to disconnect the two banks for several reasons.

1) you avoid drawing down both banks while camping.

2) Starting and deep cycle batteries are charged differently so being able to disconnect them makes it possible to charge them separately.

3) When parked you don't want to overcharge the starting bank while charging the house bank.

4) You avoid pulling your house bank down when starting.

You can use a manual battery switch, a relay or a diode based battery isolater. The diode based isolater will draw some power itself and prevent the batteries from getting a full charge. The relay and manual switch avoid that. The relay is automatic and saves you from those "duh" moments where you forget to disconnect the banks when camping.

Here's my current/proposed list of elements for the schematic i posted on the first post. Do i go with 50A instead of 30A? Do i go with Pure instead of Modified? Tips on where to buy the batteries? why get two/four 6v over one/two 12v?



30A Power Adapter: Robot Check

30A Power Inlet: http://www.amazon.com/gp/registry/wi...quiresSignIn=1

Inverter/Charger Option 1 - 2000 Watt Modified: Robot Check

Inverter Option 2 - 2000 Watt Pure: Robot Check

Inverter Option 3 - 3000 Watt Pure: Robot Check

Remote Control: Robot Check

Automatic Transfer Switch: Robot Check

24-space Breaker Panel: Shop Square D 48-Circuit 24-Space 100-Amp Main Breaker Load Center (Value Pack) at Lowes.com

12-space Fuse Block & Cover: Robot Check

Battery Bank: still researching. any tips/places to look?

Battery Monitor: https://www.altestore.com/store/mete...onitor-p11263/

Isolator: Robot Check

What appliances are you planning on running? Will you mostly boondock or mostly plug in?

mostly plug in, honestly. but want to set up to run off a generator if needed:

phone chargers
mini fridge or chest freezer
electric stovetop
lamps
outlets
USB ports w/ outlets
hair dryer
water heater (for shower/sink)
toaster

Most of that AC stuff is high drain so go with the 50 amp service, a 2 phase generator and, if you want to run much of that off batteries, a big ass battery bank and inverter. Basically, you're powering your house.

6v golf cart batteries hold up better than 12v deep cycles, particularly when you're deep cycling them (draining them completely). For good battery life, only drain them down to 50% charge (12.1v).

ok, thanks! that was just a list of things that we'd possibly use sporadically. the things we'll use more often are:

AC
air conditioner unit
tv
laptops (2)
phone chargers
mini fridge or chest freezer
water heater (for shower/sink)


DC
vent fan in bathroom
stereo
speakers/mp3 player
water pump
ceiling lights (6 bulbs)

Hey, I'm a little late here. But I learned a lot from reading handybobsolar's battery puzzle.

For inverters he seems to really like magnum brand inverters, which is why I bought/am going to buy a magnum mms1012.

For batteries, he seems to push crown deep cycle 6v and trojan t105's which is probably what I will get if/when my dumpster batteries don't work out for me.

That said if you see any fork lifts or rider jacks by a dumpster, take the batteries!

hey man, i made a google doc with all of my electrical stuff in it and could really use someone looking it over before i commit to purchasing materials. would you mind having a gander and letting me know how it looks? there are a couple questions in there if you don't mind:

Water heater (demand) should be propane, not electrical.
Ceiling lights should be replaced by LED lights.
You can also charge your cell phones on DC power.
Air conditioning? Try opening the windows/roof vents unless you live on the outskirts of Hades.
