so what are the amp/hr totals you are using for your battery banks?
3 - 12 volt / 114 amp interstate (1)/everstart Maxx (2) batteries 342 amps total.
how many batteries are you using and why?
3 batteries Group 29/31 size, Limited by mounting space and cost.
in that would you want more batteries / amp hours if you could get a smaller/lighter battery with more a/hr ?
If I were stationary, I could have a "portable" battery box that contains more batteries connected via heavy duty connecter to the batteries mounted on trailer
Using Trojan batteries would increase my costs by 50% or more and increase my total capacity by about 100 Amps. A taller battery box and more tongue weight would also be issues that would need to be addressed.
what would be a average a/hr battery bank that s currently common? 200,400?
for those boondocking can you give me a idea of what your average amp draw is per/hr or per 24/hr?
I run 100% of my 12v system off my solar system and no longer use the shore powered charge controller.
I use about 600-1200 watts per day when connected to shore power and roughly the same when on battery only. A bit more in late fall/early spring if relying on furnace fore heat.
Adding a larger inverter would add using microwave capability and could potentially heat water from excess solar power.
small inverter used to power TV if necessary.
Solar system power details.
I have 9 panels x 85 watts. (765 watts total solar) My panels are 32v panels using serial/parallel connections to keep wire sizes and power losses in cabling to a minimum.
3 strings of 3 panels each allow for power generation early morning to very late in the day along with fairly shaded conditions.
This system works well to supplement when on 30 amp power as I can dedicate shore power to heat strip heating/dual air conditioning and microwave. Rarely trip breakers on 30 amp since I wouldn't have the converter or water heater using shore power competing with the hair dryer and air conditioners.
