Da quando ho acquistato un misuratore digitale ora sono ossessionato dal controllo del grafico. Un’altra tana del coniglio in cui saltare, evviva!
Sono stato fuori questo fine settimana e ho impostato la caldaia/riscaldamento sulla “modalità vacanza”. Ciò significa che niente acqua calda e niente riscaldamento (a meno che la temperatura interna non scenda sotto i 18 gradi, ma è improbabile che sia molto ben isolata).
Oggi ho controllato i grafici e noto “sluipverbruik” di 0,050kWh alternati a periodi di 0,190kWh. Per un totale di quasi 10kW al giorno (in realtà di più perché il mio solare ha compensato). Lo trovo abbastanza alto. Quale potrebbe essere il colpevole? Dato che è ciclico, penso a una pompa (CV o ventilazione) o a un frigorifero/congelatore?

Buy the p1 meter and some plugs.
“Meten is weten” as we say.
My fridge is about 80watts for 10min each 4 hours.
Your explanation doesn’t make a lot of sense. kWh and kW are not the same and it’s important to use the correct one.
kWh = the quantity of electricity (over time)
kW = the ‘strength’ of the electricity at a given moment
So if you say you have a sluipverbruik of 0,050kWh I’m going to assume you mean 0,050kWh per hour. Which would be … 0,050kWh. You have a sluipverbruik of 50W.
That is not a concerning amount, just some electronic devices on standby and your fridge. I wouldn’t worry too much about it.
Also the data in the screenshot makes no sense. It’s talking about ‘injectie nacht’? That’s a very special kind of solar panels you have… the graph clearly shows that the injection is happening during the day?
Can only guess and talk in ‘maybes’ here…
First idea: it really does look a lot like the way many heat pumps cycle.
Also: fridge/freezer typically doesn’t run 3 hours in one go and ventilation should be on permanently but even if they would cycle like this, should ideally not consume 140W.
> (unless inside temp dips under 18 degrees, but unlikely as very well insulated)
With the temps and winds we had it needs to be *very* well insulated, or in an appartment, or the temperature should have been quite high when you left. Also depends on whether that 18 degrees is set as hard threshold or rather ‘make sure not to go under 18 degrees’.
Something doesn’t add up with your explanation I’m afraid. You’re saying you have 0.050 kWh “sluipverbruik”: What kind of timeframe are you talking about here? Per hour or per 15 min? I think the Fluvius graph you show is reporting values per 15 minutes, so that would mean it’s actually 0.200 kWh per hour which is the same as 200 Watts. That is relatively large for sluipverbruik, but maybe you have a couple of large refrigerators (or old ones, they use waaay more power) or some small home server running that could explain this usage.
Still, the numbers don’t add up to the reported 10 kWh a day offtake, that would mean it’s closer to 555 Watts continuously (taking into account the ~6 hours where your solar was exporting) and that’s really not sluipverbruik anymore.
EDIT: Those periods you mention with 0.190 kWh are again per 15 min, so actually 760 Watts, which is most likely due to some kind of heating still running intermittently.

200w sluipverbruik geeft 4,8Kwh op 24h
Get a plug in battery of 5kwh to get rid of 80% of sluipverbruik
