Good day all,
I find the low voltages and lack of panel optimizers quite limiting in my Victron install. As a result, I would like to install an AC coupled pv string inverter after my victrons on the critical load side.
However all the reading I am doing talks about frequency shifting, which to my knowledge only works in off-grid mode, I am not off-grid but rather running ESS.
How do I go about adding a pv inverter with the grid functionality?
Frequency shifting also works in ESS, in some countries its illegal if it doesnt do that
Pv on critical loads is fine, just keep sure you follow the 1:1 rule
The grid will be planted at 50.0hz ?
Also how does the monitoring portal then work? It will need to read some production value out of the PV string inverter?
If your connected to grid, the frequency shift can be done by your grid provider, in some countries its illegal to use a inverter that cant
When grid connected, surplus can feedback to grid if your grid provider accepts that
If no grid feed, the multiplus 2 can control freq to stop or limit the grid inverter, but only on ac out of multiplus 2, not on ac in
a PV meter like the ET112 can measure the PV and pass data to system
Why do you want to go ac inverter route? DC is much more efficient with battery storage
