Hello all. Looking for advice as I build my off-grid system for my tiny home. My current dilemma is that my batteries can be configured as 24v or 48v systems, and not many of the 48v systems are configured directly for US, split phase.
Option 1 is use the batteries at 24v and use an inverter/charger(quattro probably), adding a second unit for split phase in the near future.
Option 2 would be use the batteries at 48v, with a EU inverter/charger run it at 240v, plus an autotransformer.
Is having a 48v system worthwhile in terms of longevity and efficiency to justify the slightly more complicated system? I'm also not sure how I could charge my pack with a 120v inverter generator through a 240v configured inverter, when I need generator backup. I like the idea of having the autotransformer in the long term anyway to balance loads for split phase when I use tools, but the AC charging from a generator is the biggest unknown to me right now.
I am using 48v system. there is less I/R lost on a 48v system. You can use a 120v quattro and wire in an autotransformer
