I was ready to sell my Rack Mounts and replace with this, but then I read the manual and with 1 18KPV, you can only connect 3 of these. whump whump. I do like these but I am actually thinking of adding even more batteries, as 60 kWh isn't enough for me, so 45 definitely isn't gonna do it.
If I didn't have my rack mounts, I'd def consider these, but that 3 per inverter limit is a killer.
I am wondering, however, if the 3 per inverter is a limit of the 600 AMP busbar and the wiring? What if, instead of 2/0, you used 4/0 from a bank, could you then get 6 connected to one 18, as two banks of 3 each?
