I recently swapped my off grid system from 24v to 48v. Everything but the batteries are from Outback Power. This included rewiring my 24v Lifepo4 batteries into a series parallel configuration, buying new 48v inverters, and reprogramming my charge controllers to 48v. I've noticed my 8.7Kwh system never really gets more than 5.5Kwh output ever since swapping over a month ago. I checked the breakers at the panels and they were all fine. Only thing I can think of to check is I potentially left something unplugged in my battery shed but can't think of what.
