hello all I acquired 6 6v crown 305 batteries from a lift. they do not have an amp hour rating it is amp hrs and time so after searching they are 20Hr 15.25A 305AH / 5hr 24A 270AH. they are currently in series for 36Volt but there is no 36 volt inverters.....so to use all 6 if i wire 3 series strings 12V and parallell the three i should get 12Volts 960AH.
after kinda figuring out the C-rate and i said kinda, if i want to run a 2000 watt inverter at 12V i will be pulling 190+ amps from the bank ( I assume 31 amps from each battery) but if i only use 4 in series i would have 1220 ah at 24V and only pull 80 or so amps total
not sure which scenario is better for the batteries and have not figures out a charge controller situation since i figure if i pull 190 amps out i need to put 190 amps back in and since panels are only like 9amps i would need a field of dreams to put them in.
any basic help on this to clarify would be great.....it seems everything i look up gives me an answer that raises 20 more questions.
I started this project to run 2 freezers and a fridge since i work 12 hour shifts and the power always goes out soon after i leave and although i have a generator im not there to run it and if i start it and leave it will run until its out of fuel wether the power comes back on or not.
all 3 units pull 4.76 WH a day or 198 watts, the reason for the larger inverter is i would like to run the furnace blower which is around 2280 watts but without 2 more batteries to make a 48 volt system i dont think i can run a 3000 watt inverter since the amp draw would be so high. tired of calculating and scratching my head and figured i reach out for some help.
thanks to all who may reply
