Charging Without using Batteries

I would like to not use my batteries for charging the EV.

I can of course manually set the batteries on keep charged, but I also do not want to charge them if not at 100% during EV charging . Is this possible in VRM or Venus ?


hereby you see Pylontech batteries dropping during night scheduled EV charging process

I would like to avoid unnecessary cycles on the 21 kw Pylontech Bank

Yes it's possible using NodeRed. You musst programming this yourself.

In the case described above, the battery inverter is simply deactivated if a charge is detected on the car battery between 10pm and 6am. as soon as the charge stops, the inverter is activated again.

Great job ! thanks a lot.

It is a bit too early for me to use Nodered but I will certainly do.

But I think this should be a nice satndard feature in standard tools.

Et je vois que tu charge la tesla de nuuit ;-)
