The manual for the 3 Phase 12 kW says on page 20 "The recommended AC Breaker is 20A for 8kW, 20A for 10kW and 20A for

12kW." I would think this is a bit small because the maximum pass thorugh load is 20 A. (At least I would think so - the datasheet says 60A, but I presume it is the total current, not per phase or it would be a very big inverter). With the 25% extra capacity I woudl specify a 4P 25A breaker, or maybe a 4P 32A. But on page 29 of the manual they state under "(2) AC Breaker for grid and backup load" as 32A - which is fine, but then under the heading they state "(3) AC Breaker for grid and backup load" as 80A. This does not make sense to me. The inverter cannot deliver that much per phase. Are they confusing per phase and total currents again, or am I missing something?
