I have a 36kWh 24V SLA system in bus (chosen because it matches my bus and my 7kW bus alternator, which is great for charging on the road).
I need to switch to lithium (probably LiFePO4), because SLA is a joke and has endlessly failed to meet it's specs.
I don't need it to be as large, because I don't use the bus as much (and lithium gives me a much bigger discharge range), but here is what I would like.
1) Storage of 3-6kWh
2) Output of 3kW or more (120VAC)
3) Ability to charge off my 1kW solar bank (runs up to 100+V - or I could keep my solar MPPT and charge off 24V output)
4) As high a charge rate as reasonably possible from my 10kW generator (120VAC)
5) Nice to have: The ability to charge off my 24V 7kW bus alternator for charging on the road.
6) Nice to have: Remote panel and/or app control/monitoring
I've been looking at just buying something like the AC500/B300S and dealing with losing 24V input, but I have a feeling that if I knew which components to buy I could get everything I wanted for the same price or better.
I designed and built my current system consists of the 24V battery bank, two Xantrex SW4024 24V 4kW inverters, an 80A 24V MPPT solar charger for my 1kW bank (and a backup charger) - so I'm comfortable dealing with connecting all of this together, but what I *don't* have right now is the time needed to learn about all of the options available in the lithium world to replace all of this. It was a fun project the first time around, but my time is too limited to do all the research *and* do the replace/install, so I was hoping for some pointers
So:
1) Is it easy enough to just get the components to put together a lithium system like this?
2) If not - a suggestion of what I should get, and is it difficult to find a large enough buck/boost that could convert my 24V inputs to charge the bank?
