Hi, have just had a new system installed with 3 strings on 2 Fronius primo inverters - one 12x315W north facing panels and one with 7 west and 8 east. Also have a fronius smart meter to limit export to the 5 kW limit.
Currently the problem is that the EW inverter is in the shed and does not have network access so there is no way to get generation data from it. Solarweb is a bit confused by not knowing the generation of the second inverter, but is showing total grid export and consumption, so I have a good idea of total output. It does usually, but not all the time, show zero power use during power generation - not sure how this works - either it doesn’t know how much self consumption there is and should show no power use at all if there is export, or it does know and should show a small amount of power use all the time…
Anyway, on to PVoutput, I have set up the push (single inverter, meter with &delay=3&auto=1 and logdata) and am getting data ok, but I just see power consumption (which is usually zero during generation) and generation for the single inverter that is connected.
- until I get the network cable installed to connect the 2nd inverter, is there any way to see the total exported instead of just the single inverter?
- Why am I seeing 0 power usage most, but not all of the time while generating? Based on nighttime usage I’d expect about 100-300 W usage during the day.
- I’m not 100% sure on the parameters that I should be setting in my push file names. I’ve set auto=1, but it is not clear to me if the meter is sending net or gross data - obviously my actual export to the grid is net (ie I use power from my array and excess is exported to the grid.)
