Hi,
PowerAssist factor of 2 multiplies AC input current limit x2 for assist function. So if I run 2xES(MP2) 24V 230V 3kVA in parallel, assume power assist x2 is duplicated as I have two units?
1. On the input side I have 25A (type C) / 230V breaker coming in from the grid from the operator.
2. On ES2 AC input limit is set to 12A (so 24A for parallel single phase setup as they both connect to the same phase).
When PA kicks in, I would expect it to be 12*2*2 = 48A / 230V = 11kW (5,5kW from the grid + 5,5kW from the 2xES2)?
I ask this since my setup struggles to start a 2kW pump, understand in rush current but sizing should not be an issue. Cables are 50m2 x 3, connecting bank of 740Ah of 24V lifepo4 batteries running in parallel (3 banks each with a 200A BMS) for total of 600A current discharge.
When the pump starts, everything goes dark. No beeps, errors, logs. Bzzzt, gone.
No ESS. This is off-grid setup (with AC ignore for load and SOC conditions) but with normal grid available as needed. No generators or weak AC sources, no issued to sync with the grid etc. Almost like speed of transfer kills this setup.
VS is off, assistants are setup as per below. Generator flag is used for AC ignore, grid is tied to both inverters with same lengths/size of cables (same for DC) and 2x32A breakers.
