Dear Community, I am completely new here, and this is my first message here. So if I do something… What is not allowed or something else should… Tell me, so I can learn from it. About three months ago my Victron home battery started working. I installed it myself. And that was actually surprisin…

Mine starts approx 20-24minutes late, so it miss minimum 20minutes of ie infeed at a higher rate. Have not used dess much since it do not fit our differentiated buying prices in Denmark, so have no clue why it is delayed.

I just went live with my Dynamic ESS in the Netherlands (3x MPII 5000VA, MPPT RS 450/200, 64kW Battery Bank) and I see the same behavior. Did anyone figure this out yet? Thank you for the question and thank you to anyone sharing some insights. Kind regards, Cees

No, unfortunately, no one is responding with a solution. I do notice that sometimes it works out fine, and everything happens on time. But often it doesn’t. It’s a strange problem, because I hear from others that they don’t have this problem at all. So I don’t really know where to look…

Make sure you set the correct maximum import and export power, DESS uses this to determine when it should start charging/discharging to get to the target SOC.

Did you set your home location in VRM? Maybe this is related to different time zones, day light saving or just a bug. The 15 minutes late might be subject fetching data and rescheduling the target SOC. looping @dognose in…

The vrm currently has major issues also displaying dess data today and last days unfortunately. Maybe this also interferes with the scheduling. [image] VRM lots of malfunctioning VRM beta The vrm portal has serious issues last weeks where it’s unable to show i…

Yes, I checked that. The problem isn’t so much that it miscalculated how long it takes to reach a soc. It’s more that the energy price peaks at, say, 8 PM. And my system won’t start delivering until 9 PM.

Yes, I checked that. Unfortunately, it’s not that simple. But thanks for the tip!! It’s probably something really stupid…

Well, I noticed that too. Various information wasn’t loading correctly. And the website was very slow. But the problem this post is about… Unfortunately, it’s been around for a while. And actually, it’s been around since I started this system in February.

I had the same problem. I reset the consumption data in the VRM portal. And since then, everything seems to be working fine. Just today, DESS is doing some crazy things. I think it’s not getting any data anymore either just like de VRM portal.
