Just starting to put together a small off grid system. I have purchased 8 of 6 volt batteries fRolls S-550, that are 428 AH capacity each. Was told to do two strings of 4 and parallel them to configure a 24v battery bank, that gives me 856 ah. I purch. a 110 vac, 24 volt CC at 40 amp capacity rating, as per installer recommendations. After researching company battery site, they recommend CC should be 10 percent = 85 amps. Am I missing something here!!
I have not used the CC and can exchange it for a higher amp model. I have purchased nothing, but the batteries and CC.
I purchased the Cabin, and it had a 6500 watt diesel gen 120/220 capacity. The cabin is wired for 220v. Reason, it has two 1500 watt base board heaters & electric water heater. Only other source of heat is wood stove. All fine with me, and won't be using the BB heaters / water heater when on inverter, LOL. I have breakers turned off.
The well pump is 110vac that draws 12 amps when started up.Cabin has propane fridge and stove, but want to remove PP fridge, and go with AC fridge. This will save on propane, as I will be able to shut of supply when not at cabin. I will then purchase an energy efficient AC fridge and Inverter. Shut down fridge until I can charge battery bank with solar and then wind. Still need propane, as cabin has propane stove, and will be installing a propane on demand hot water heater.
I removed the electric hot water heater.
The cabin was powered only by generator, but I want to install a solar supplement system with AC Inverter. This will allow me to watch TV at night with some LED lights, and keep the AC energy saver fridge running, while at the cabin, and run the well pump. I might have a need to keep fridge going for 28 days when I am at work. I could shut it down and remove items back to my house if that becomes a problem. And that's my delima right now, have no solar / wind charging ready to go. Don't want to do a AGS, as I won't be at the cabin, and don't like the ideal of a gen running unattended.
So, for now, will shut down inverter when not at cabin, until I install solar and then wind.
Plan to use the generator when needed and to keep my batteries charged after using, for the time being. I will install solar panels in the very near future / 6 months. Also will look at a wind gen too.
I am considering now going to 48 volt system, but really don't know if that is needed. After reading info on this site, it appears to be a wise decision, and will allow me to expand if needed. This cabin is remote, access only by boat/plane/argo/skidoo. Can't drive vehicle, and no grid power.
I will only be using battery bank to power TV/Sat Receiver/Stereo - 300 watts/Energy Efficient 10 cubic fridge/LED lighting inside and out/110 vac well pump.
The time being away from cabin is apox. 28 days and could be 42 one a year. I will do a solar array to at least keep a trickle charge on batteries. Will always top them up before leaving with gen.
So, is it best for me to do a small 48 volt system now and go with a 4k inverter? I have purchased only batteries and can exchange the CC for a 48volt!!
I can easily configure the batteries to 48 bolt and that would only be one string. More efficient/effective to charge and maintain in the long run.
Appreciate your advice, as I am really just getting into this, but eh, KISS, and do it right the first time, money saved and well spent.
