To explain what is happening I have to say that I have a Spanish tariff. Which has two powers, peak power (the meter has this power from 08:00 to 23:59) and off-peak power (the meter has this power from 00:00 to 7:59, weekends and national holidays with fixed date). My house until recently had 3.3k…

I think I understand your problem but I also think that is not necessarily a Victron bug. The input setting for the multi’s allow you the limit the input. That decision is yours to make and can be due to an actual grid limitation, cabling, breaker limits, whatever. You can try two things: Set the …

My input cable on the MP II can withstand up to 40A. But I can’t configure it, it is overwritten by the Cerbo GX. I’ve moved my (non-critical) loads to AC-OUT 2 temporarily, let’s see if the Victron team can do something. The first option should accomplish what you need. Keep the grid at 5A for b…

Not sure I fully understand what I’m looking at as there is a mix of screenshots where the Multi grid current limit is configured at 6 and at 40. Both are greyed out. Whereas in your original post the setting is blue, available for customisation. I only use ESS/DESS so I am not that familiar with t…

It does not appear in blue because I have set in the VE Configure that it cannot be overwritten. The problem is that it is limiting the input and output of the multi input. It should not be varying the amperage of the multi input when I have an external meter. By limiting the amperage that comes o…

You mean the overruled by remote setting ? I have that enabled in my setup so I can use the Cerbo to change it (taken from txt export of VE Configure): TAB: General System frequency 50Hz Shore current 25.0 A Overruled by remote checked Dynamic current limiter unchecked And the settings in the …

I have the same issue with Peak shaving. As soon as you activate the import Limitation in ess/peak shaving, the Limit for ac input is reduced to the same current. If you have a system with big peak loads on ac in and a small limit for peak shaving this leads to reduced output power (to ac in) of th…

Finally someone has the same problem as me. Let’s see if it can be solved now.

Could it be that you are hitting some kind of grid frequency issue or voltage drop causing this ? It is not likely to be a Venus bug as you seem to have the same problem if you disable “overruled by remote” ? The multi’s are able to generate a healthy and powerful ac-out but have to adhere to grid …

[image] The frequency drops that I have in the graph are when the network has gone down due to power limitation. You can see that the Multiplus has not exceeded 1kW at any time to cover consumption of more than 3kW. Here you can clearly see the problem.

BUG: Peak Shaving is limiting my output power through AC-IN which causes it to not trim as configured. It only happens with external input

Beta testing

Yes, I was testing by disabling the overwrite option with Cerbo GX.

I have the configuration as above and it still limits the Multiplus II input. I still have the problem. It is limiting my output due to the current input.
