Thank you so much, I'm still learning all about how this side of electricity works. My biggest concern is reliability, then performance then price. Weight and size doesn't really play much of a factor and we use this primarily for day trips so having tons of alternator power really helps keep the battery charged.
Problem i'm running into is there isn't many 24 to 48v converters and I haven't found any that do high power and will be at a voltage that'll charge the batteries. Looks like I'll have to get 6 Victron Orion-TR 24/48 8.5a/400w converters and run them all in parallel to give me 2400w then 3 Orion 24/12 70a/840w converters to give me 2500w. This should be just enough to power 2000w AC unit on either/both system minus any losses and maybe cover my 100-150w idle load on the 12V side. I ordered one of each so will try it out hopefully using a couple spare batteries i have to make 24v. 9 converters will take up quite a bit of space and i'll likely need to add fans and some metal mounting to act as a heatsink if I'm planning to run all at full power. I guess one of the benefits is redundancy as well as ability to use switches to control how many are turned on and when... Thinking a couple switches on the dash, one a 3 position 12/48/both and other 3 position off/half/full. This would give me a ton of control in how I want to use that power compared to performance and fuel consumption.
Another option would be to swap the alternators and use the large 270a one for my chassis system and then swap the old chassis with a pair of 24V alternators, wire them together and use the wakespeed i have to regulate them both. I'm just worried about it not being clean enough power for lithium when using 2 alternators in series with a high load like twin 200a 24v alternators pumping 10kw into a 48v system. Maybe this will be the next phase of my build when I want to take the genset out.
