The problem is the 12v batteries are approximately the same physical size as the 6v batteries and less than half of the capacity of 2, 6v batteries.. I would just get them again but now I don't trust them/
What is my cheapest option? Just go to Walmart and get (4) 12V golf cart batteries?
So far I haven't seen the Trojan made batteries in the Medford, OR. Costco, they have been selling GC-2 batteries made by Interstate, those are of outstanding quality, but I've heard that Trojan makes great batteries as well and that price is very good.How about something like this?

I would spend a few bucks more and get the Crown battery.How about something like this?

I never mentioned what these were....
Granted, we used a much more expensive, indestructible, 6-volt battery than this one (the CR-205), but for the price I think it would be much better than the Toejam.
Nickle iron are great if your pocket can support them. I've personally had all the 12 volt equipment I want I'll stick with 48 volt thanks. Greater efficiency, less heat and longer life from my experience.With all factors considered and based on my past experience, I am an advocate for Nickel Iron batteries and 12-volt systems. The initial cost of larger gauge wiring is well worth it. Inverters create more dependence on foreign manufacturers and a link of inefficiency. My idea is if one wants to go off the grid, then learn to live with fewer appliances and use alternative ways.
Our 4,000 watt pure sine wave inverter/ charger which is made by Magnum Energy, I believe was made in Everett,Washington, however, since the US make next to nothing anymore, I'm pretty sure most all the parts come from foreign manufacturers, probably so do the batteries and the wire to connect them to whatever equipment we connect them too. We decided to run on 24 volts because that's the operating voltage of the inverter/charger we wanted to get and running on 24 or higher voltages makes the inverters far more efficient. The inverter system we bought is stackable and we could stack up to a total of four for 17.6 KW, however we look to be as minimal in power usage as we can and I've mentioned this before, when things go bad (SHTF situation), we will use up all the things in the refrigerators and freezers, asap and shut most all battery powered things down, sooner or later all batteries will fail, we designed our prepps in accordance, the future will be candle and oil lamp lighted. Truth is we can afford lead acid batteries and more than likely they will give us just the usage time we'll need.With all factors considered and based on my past experience, I am an advocate for Nickel Iron batteries and 12-volt systems.

I could have gone with a 48 volt system, Magnum Energy makes a 4,400 watt inverter/charger, I figured our needs and the 4,000 watt unit would take care of what we needed and as well by using 24 volts I was able to get over 1,000 amp-hours of battery storage time. The efficiency of our 24 volt 4,000 watt system is 93%, the 48 volt 4,400 watt system is 94%. Our system, 24 VDC using series parallel with twenty four 210 AH batteries equals 1,260 AH, for an extra bank of batteries to give me just 420 AH on 48 VDC would take 16 GC-2 batteries and I don't have room for that many batteries. We're very happy with what we have and it does a great job and it's affordable.Nickle iron are great if your pocket can support them.

I would love to hear what components (Make and Model) are in your system, it sounds like a good thing to emulate.I could have gone with a 48 volt system, Magnum Energy makes a 4,400 watt inverter/charger, I figured our needs and the 4,000 watt unit would take care of what we needed and as well by using 24 volts I was able to get over 1,000 amp-hours of battery storage time.

I was talking about coming straight off the batteries for 12 volt DC. I haven't checked recently but it used to be that 12 VDC appliances were all that was available in dc. If 48-volt DC appliances are available, then I would go with 48-volt dc since that would reduce the current draw for the same wattage appliance over 12 or 24.Nickle iron are great if your pocket can support them.

With the present set of batteries we've been able to run 3 days when we didn't get a good solar charge due to very cloudy weather. our inverter is a pure sine wave 4,000 watt Magnum Energy, 120-240 Volts AC model MS 4024 PAE, the solar controller is a MorningStar MPPT 60 amp unit, I believe it will take up to 150 volts DC from a solar array and can be switched for 12,24 and 48 volt battery system.I would love to hear what components (Make and Model) are in your system, it sounds like a good thing to emulate.
Checking my math (V,W,A,Ah), does your battery bank give you between 8 and 16 hours of standby power?
