Folks, I have a system running where the Load balancing or the grid current limit does not work. The situation is as follows: 3xMPII 5k VM-3P75CT as grid meter (roll → grid meter) Loads on input and output The system only looks at what enters the MP via AC in and responds well to that. But if so…

Hi LX, I’ve tried to set the limit om 10A as well. The system just doesn’t take the loads in front of the MP’s into account. When I put everything on ACout the peak shaving works flawless. Yes I did update everything to the latest versions. No beta. In the mean time I found this posting from @Smar…

If 25A is the max through then set it lower. Heat derates switchgear anyway. (Recommended 20A) Best to leave headroom.

[image] Rik: The system just doesn’t take the loads in front of the MP’s into account. This is a useful remark. What metering are you using? How much of a load? The problem is for some it is a set up problem. Some are half updating firmware. Or using a mix of beta and old firmware. And there…

I use VM-3P75CT as grid meter (roll → grid meter). There are 2 3-fase PV inverters metered with a ET340. AC PV can do max 17 kW so it will never exceed 17 kW my 3 x 25A grid connection can handle. I did not test yet what happens when DESS decides to push back full throttle while the PV inverters are…
