I am planning a solar/electric powered boat. The plan was a pair of 6kW arrays, each running through a EG4 6500W inverter/charger to a pair of 40kWh, 48V banks. The problem is the 55hp, AC-20 motor is to be run at 96V. So, I THOUGHT I could run the two 48V banks in series BUT EG4 support says nope. Won't work with their BMS and you'd likely get charger faults.
Can I use a pair off the shelf 48V chargers (like LV6548) to charge a pair of 48V banks connected in Series to power a 96V motor? Or will all the off-the-shelf inverter/chargers and/or BMS end up with faults/errors/shutdowns? I don't want to spend $30k and have it not work.
The split phase 240VAC you can get from having the 2 inverter/chargers communicating is nice to have, but I can deal with only having 120VAC if it would be required to have the units isolated.
Thanks
