February 14, 20233 yr Hello 😊  Having a brain fart here.  With a 12kw 3phase Sunsynk.  There is a load of 3500watts. It is a 3 phase machine and has a Neutral.  Now is the power per leg or phase 3500/√3 =2023watts per phase ?  or is is a simple 3500/3 = 1166watts ?  I want to know how much power will be on each phase so I can better balance the loads.

The inverter need to supply a 3.5kW load and at PF of 0.8 the inverter might have to supply 4.4kW. Each leg will thus need to provide 6.32A at a 230V to N at 120 degrees apart. 400V ph to ph. Adjust for different power factors. May be PF is not taken into account? Tell me I am also not on the same bus
February 14, 20233 yr Author Well my concern is the 12kw Sunsynk is rate sat 4kw per phase, I need to them add another single phase 2.4kw to it.  Basically I will have a 3phase load of 3500watts I then need to also run a single phase item of 2400watts and I am worried if I add that 2400watts to one of the phases it would I overload that phase.Â
February 14, 20233 yr Author Thinking, as you did getting the amps per phase or leg I can then multiply that with 230V to get the watts per phase. I was not sure if it would multiply by 400v or 230v but you correct in that each phase is the potential of 230v.  Â
