I agree and am learning how all this works. 12, 24, 48 volt. If we go with higher voltage we can have lower amps and smaller wires. Also MPPT charge controllers can handle twice the PV input voltage when going to voltage arrays. Backwoods solar.com has a great catalog that has explained a lot of...

im looking at options. I agree that more parts can equal more failures sometimes. Then again I don't want to put all my eggs in one basket. re the batteries I agree that putting batteries in series (that have their own individual BMS is a bad Idea as I am learning-thats why I asked the...

Where do you get your components and Li cells? are they grade b or a ? I appreciate the info on what your using for components. thanks

I do like the ability of setting both overcharge and discharge limits to maximize the life of the expensive Lifepo4 batteries. I think the majority vote goes to ONE 24 volt instead of two 12 volt in series. Having the BMS of one battery shut off and blasting the remaining 12 volt battery, like...

Thank you for the reply. Your advice makes sense. The BMS with two 12 volt batteries in series would create potential problems that I should avoid. Have you had any good experience with 24 volt lifepo4 batteries that are reasonably priced ? I have been looking at REdodo, Timeusb, and Chins...

Rodrick I appreciate your reply but was hoping to learn what the pitfalls or advantages are for example- BMS shutting off one battery when two 12 volt batteries are in series-does this happen or not? It would be nice to just get a big 24 or 48 volt battery bank but Im interested in being able to...

Im in the planning stages of a solar system and thinking of going with 24 volts system. what’s your opinion re Two 12 volt in series vs. one 24 volt (Lifepo4 of course). I like the idea of two batteries incase one goes out, I can still get a 12 volt battery easier (especially if its covered...
