As the Netherland grid voltage varying by the influence of PV energy input, voltage levels are adjusted to the grid voltage stability by the powerlines company and therefor automatic limit the PV inverters. To be able to have a good view on this adjustment behaviour, it now cannot be logged by the Emporia unit. So please add this Voltage parameter Emporia!  Below a snapshot of my Victron inverter.

I am Curious about the IFTTT status !?

The 8 sensors i used for the logging of the electricity, were all used for other groups, so i now only can see the energy consumption in the “Balance”

Situation: EU country, 2 adults in a (corner) house with thermopane glazing and isolated brick walls, we use 3,4 MWh electricity and 1400m3 natural gas yearly. Old PV generated 2,4MW yearly so we had to buy 1MWh from the grid

Had installed an additional 6,4kWp East/West PV (extra to the 2,4kWp South we already had for 6 yrs), so now we have 8,8kWp East/South/West orientations. This will generate yearly 6,59MWh, so we than have 3,19MWh spare Netto costs per 1 kWh is €0,06

For this energy surplus, i installed a 80 Liter heatpump boiler with a SCOP 2,34

To heat a traditional boiler of 80 L water from 13deg. to 55deg. celsius, takes 4 kWh electricity bought from the grid = 4 x €0,40/kWh = €1,60

4 kWh / 2,34  = 1,709kWh x PV €0,06 = €0,10

Now I don’t know what the COO and lifespan for this new heatpumpboiler is, so no costs taken in account for that, but it won’t be a factor 16 !
and on top of that, i made valves in the air intake and exhaust, so i am able to have the cool exhaust as airconditioning for the top floor
