Hello,
Quick question around charging options.
I have access to pretty cheap second hand batteries quite often so I am constantly adding batteries and moving them around my different solar setups. I currently have in series 3 x 55ah batteries on my main grid tie but just managed to get some more batteries so going to upgrade this to 8 x 55ah 4s2p so 48v meaning I need a new charger as the current one is 36v.
I also have in my shed 2 x 55ah in series which I would like to be able to charge if I need, couple of 12v systems but I have a charger for them if need to charge them.
So the question is, instead of going out and buying a 48v charger for my grid tie which could change again at some point could I instead just use multiple 12v chargers whilst leaving them in series.
Roughly something like below
I then have everything tied into my Home Assistant so I can monitor a smart plug which would detect when the chargers have dropped the amps down to pretty much nothing before switching off the chargers and switching on the solar.
Thanks for any opinions guys, cheers.
