Hello fellow Victron fans.
I am sure this was discussed before but need some clarifications what is in fact expected. Here we have a customer that has feed-in turned off until the grid meter is changed into a dual-way one. However, each day we see huge ammount of energy fed to the grid which now the customer has to pay for.
Settings:
Last 5 days stats (notice To Grid):
Any suggestions?
What do you use as a grid meter?
Also in ESS feed in will never be 0, it will always try to balance loads on grid
There is no grid meter. The whole house is on AC Out.
Ok, but it seems way too much for just balancing. Customer has 60kw in a couple of days added to bill already. The two-way grid provider meter is about two weeks away from being installed. But it is worrying meantime.
The customer never hit DOD so never in fact had to touch the grid. However, the Multi's either pull or push through the meter constantly, ranking up cost needlessly. This back and forward is metered.
Der Mehreigentümerzähler ist nicht ausgeglichen, es ist derselbe wie beim et340. Daher stimmt die Auswertung im VRM nicht wirklich. Man sieht, dass die Deckung in etwa der Einspeisung entspricht. Bei einem Nettozähler wäre das wieder etwa 0.
You have a 3-phase system, it is also set to "total of all phases" for regulation, so it will backfeed to try keep the net usage zero, which seems to be the case on yours.
If your phases are not balanced, it is going to send power back.
Try change the ESS regulation to individual phase, and see if that changes the behaviour.
Try that for about two hours since the post above. Customer called to say that L1 inverter has gone crazy loud and hot which he could see consumption on L2. I guess it was trying to help it out?
Correct. Have a read of how those two settings work in the manual. It has a good description.
