Hello
I have a PV system including 10kw of panels, a 10kVa quattro and 8 pylontech 2.4kw batteries which makes a total of about 20kw of battery. My system works very well and I don’t have any problems. However my edf contract is with tempo. So I have 22 red days per year where the price per kwh is very, very expensive.
If the weather is bad that day and I start the day with 25% battery, the bill will be steep. I would like to know if there is a way to manually trigger the charging of the batteries by the edf network. If it’s possible I could, knowing that the next day is a red day, charge my batteries during the night (kwh is cheap from 10pm to 6am) and start the day with a 100% charge of the batteries.
The quattro is not configured in ESS, the programming was done this way because I did not have an edf contract at the time) which means that as soon as the SOC is reached (20%) the inverter switches entirely to the AC1 input (edf), gives me juice for the house and also recharges the batteries up to 100%. This means that if the batteries drop to 20% during the day on a red day, I consume not only the charge of the house but also the recharge of the batteries. At 0.75 eurs per kwh, it hurts.
If you have a solution, I’m all for it. Thank you
