How can I make DESS aware that my PV will turn off during negative price hours?
For example recently in the Netherlands, DESS made a schedule that only charged the battery as fast as the predicted PV output could handle. However, solar is almost free but negative pricers are more financially interesting. In my option, it should have made a schedule that grid charged at max capacity during peak negative prices.
Also, I’m slightly concerned that turning off PV is going to have an affect on PV prediction as that used historical data and isn’t aware that I turned it off.
Any ideas on this? My solar turns off when prices are negative. Now the ESS charges full power from grid, but it doesn’t take the fact my solar will turn off into account in the PV prediction.
At the moment energy price is negative, and my solar panels are therefore turned off. But the ESS is actually discharging to keep grid at 0 Watt, while it could better use power from grid…
Same “problem” here.
I already managed to shut off my AC-coupled PV Inverters (Goodwe) using Home Assistant while energy-prices are negative. That one was quite easy.
But my Victron MPPT’s are producing electric energy. It even feeds in to the grid when actual consumption is lower than PV-production.
There must be a setting for I guess. But didn’t found it yet.
