I assume I want all my batts before I plug them in so they all have the same amount of cycles. I figure I will buy a battery every week or two until I have 8 batts and then start building their home.
The problem with a small outdoor shed in central IL is when I'm 2 states away and it's 15 below and the ice knocks the power lines down for five hours. my batts would be trash before I return...
I want 12v cfl's and some cigarette lighter plugs around the house for charging phones and for running things that normally get plugged into transformers like cordless phones, scanner, verizon wifi card...
I assume that gets trickier with 24v
I assume with a 24v system, I could plug in some grape solar (30-36v) panels with a dump load relay...
I own an IOTA DLS-30 (30A) power supply for some ham radio gear. I can add the IQ4 to that and make it a charger/maintainer

---------------------
I have the 45 watt panels from harbour freight that I use in my garden shed for a battery maintainer/charger. I hook the leads to a different battery every couple weeks and I use the system to run 12v cfl lights in the shed.
from that I charge a battery box that has a 400 watt inverter and a pickup truck battery. I use the battery box to power my bbq shed (10x10 garden shed full of bbq equipment).I plug the shed into the box with a cigarette lighter plug and that powers indoor and outdoor 12v cfl lights. I use the inverter for a laptop and fans.
before that I built a solar powered deer hunting trailer for a doctor friend with deep pockets. He bought a toy hauler trailer to haul his argo (6 wheeler atv/boat) and we put 4 windows in it for bow hunting. It went to a welder and he made mounts for rear jacks and a roof mount for the harbour freight 45 watt panels.I charge 2 golf cart batteries from the panels. Then I used the two 5 watt cfls that came with the panels in pull cord light sockets. I then installed two 4" LED oval brake/tail lights from the truck stop that have a ring of white LED's around the edge for backup lights. I wired the white LEDs to one switch and I used a two way switch to turn on the parking or brake lights for red hunting lights. I replaced the roof vent with a vent/fan with remote control. I installed a 2000 watt inverter and some cigarette lighter plugs. I got a shop reel up extension cord to use AC outside the trailer. The charge controller for the panels have charging jacks on the front to charge things and it has a low power cutoff. I used that to trip a snow plow relay so all the power except the front jack, the fan and the inverter will shut off at low power.
To make a solid quiet platform, I installed three 3500 lb trailer jacks to lift the trailer off the ground and added rubber tile flooring.
I added 2 propane tanks and mounted a wall heater.
he had the idea of running the fan at half power and setting the fan controls to turn on at 95 degrees. The next time we looked at the trailer the batts were at 9 volts. I slapped a charger on there and charged them back up but they dont have the capacity they had new.
I still want to add a water tank, camping water heater (propane) and a stereo large enough to play music at a party. He said he will make me an offer I cant refuse when he's ready to part with it. then I will add an AC unit to the front window so I can plug in at campgrounds or peoples houses and not need to go to hotels when we go somewhere.
