Hi Edwin,
My plant is still down, so no testing from this end. Hope to keep this topic alive until I’m able to produce feedback. I suspect EPS mode (backup) prevents switching to other modes on the inverter.
Meanwhile interesting, since the plant has no grid power, the system says OFFgrid, logically. And since there is no grid, the inverter has the EPS output set (in my case 4 groups of the house) Ok for now. The reading #gridoutput is 0 (zero) and since I use this var in some flows, the calculations are off.
In resume, when you depend on flow calculations and have a EPS backup system, one should check on the #ACcurrent var also.
