Hi Edwin,
Yes, that was my initial idea, but that does not work, as the “Active Power Limit” is always a percentage of the max output of the inverter. In my case 4000 watts.
My goal is to calculate the “missed production” as a result of the throttling, so I can calculate with the PBTH price what my savings are.
My question was if there is another systems parameter from the inverter that somehow tells you what the max power at a certain moment was.
Example
- Current Solar Power: 2549 watt (Solaredge Inverter)
- Current Power P1 meter: -2378 watt (Homewizard)
- Calculated power use: 2549 + -2378 = 171 watt
- Calculated Active Power Limit: 171 / 4000 = 4% (rounded)
In my flow, I use this to dynamically calculate the Active Power Limit to maximize self consumption but to minimize export to the net.
However, once I do this, there is no way for me to get back to the 2549 watt from step 1.
Question
Therefore, my question is: is there a parameter from the inverter that tells me what the actual power is before the throttling occurs?
See the flow I built below:
I hope this clarifies.
