I’ve been using grid setpoint succesfully for months now (since installation)
But this week I noticed my monthly peak was 10KW when i set a max grid setpoint of 8.
I noticed it too late so not sure what the cause was until now, it was pulling 12KW when grid setpoint was set to 6.8kW!
Why is this happening? It seems it wants to pull the full house load from grid.
Now that it’s winter i’m pulling more power, is this a feature I’m not aware off?
Hi is batterylife active?
Mode is “optimized (without battery life)”
Today i noticed something similar. Just the entire load came from the grid and the batterie was idling at 73%. I had to restart everything. Waiting for 5 minutes.
Meanwhile an update was installed for the ess assistant but it happened again.
Maybe I am wrong as I am not using ESS, but isn’t “Grid setpoint” somehow related to when to get from grid and not how much to get?
Interesting. I also don’t use ESS, but might do so in future. It seems many people misunderstand what this is supposed to do.
I use ess for a few years now,
gridsetpoint is the value the system will try to keep the grid use (for example 50w) or the grid feed in (for example -50w) at
best is to keep at a positive or negative value , 0 will not work very well…
It worked just fine. And now for some weird reason and only at certain times it just matches the AC out load, like it’s just peak shaving. Which is not enabled as it needs an AC in meter
So do inunderstand it right that you dont have a grid meter?
and are there any loads or pv on ac in side?
i also see scheduled charge in your second picture so that makes sense for the grid feed to loads..
Can you please make screenshots of the whole dashboard, not only a small part?
So we can see better what’s going on in your system.
No seperate grid meter no.
Nothing is on AC in, all AC out
Not sure where you are getting scheduled charge from? All schedules are disabled
I don’t have a full screenshot of when it’s happening of vrm
But here is on the console from this morning
Good catch, I did not see that. So I guess that is the bug…
Also weird that it’s not actually charging but just covering the load..
On certain moments I would actually like to able to do this but I wouldn’t know how. But now the schedule is activating when it’s disabled..
Give us some more information about your system.
What components do you have?
How is everything configured (VE.config incl. assistants)?

You said nothing on ac in? Now you say you have pv on ac in, but its configured in vrm on ac out
If thats the case, thats why its not working, you will need an grid meter to get ess to work properly with pv on ac in
