Energy meter AC loads - PV = grid

Hi,

I have two energy meters ET112's. Grid, PV array and loads both on AC in.

If the meter on loads is set to grid meter (wrong for mysetup) the ac loads is calculated as follow grid + PV = AC loads.

However it doesn't work if energy meter is set to AC loads ie AC loads - PV doesn't equal grid in VRM.

Is there a way to do this?

Thanks,

Matt.

Your setup should be

Grid -> Grid Meter -|

| - PV meter -> PV inverter

| - Non Critical Loads
| - Victron Inverter AC input -> Critical Loads

This way you will get 4 blocks on VRM: GRID, PV, AC Loads and Critical Load

Is there a way to get AC loads as the ennergy meter number instead of grid?

Grid -> energy meter 1 -> PV (shed)

Grid -> energy meter 2 -> house with energy meter

I was hoping to use meter on house and meter on PV and then calculate the grid number.

ie grid = house - PV.

It works the other way around is House (ac loads) = grid + PV but venus os doesnt seem to support the other way around


It's not easy for me to add meter before the split of the feeds to shed and house. Hence this situation
