Nicht jeder Shelly kann erzeugte Energie negativ darstellen. Bei Shelly mit Wandlern z.B. PRO 3EM und Pro EM ist es wichtig, dass die Wandler-Richtung korrekt ist. Quote Translate Revert translation?

Das Saldieren muss ja im 3-phasigen Shelly PRO 3EM gemacht werden (installiert in der NÀhe des Hausanschlusses) und der PRO 3EM kann ja gar nicht wissen, wie konkret eingespeist wird. Ich habe einen 3-phasigen WR, aber zeitweise misst der Pro 3EM nur auf einer Phase Einspeisung (negativ), auf den anderen Phasen entweder 0 oder sogar Netzbezug. Bei 0 wird halt alles direkt im Haus verbraucht. Es kann gleichzeitig auf einer Phase sogar Netzbezug auftreten, weil der Hausverbrauch höher ist als der WR auf dieser Phase aktuell leistet. The balancing must be done in the 3-phase Shelly PRO 3EM (installed near the grid connection) and the PRO 3EM has no way of knowing how, i.e. on which phases, PV power is actually being supplied. I have a 3-phase inverter, but in some cases the Pro 3EM measures export (negative) only on one phase, while the other phases are either 0 or even draw from the grid. 0 means everything on this phase is consumed directly in the house. At the same time, there may even be grid consumption on another phase because the house consumption is higher than the current output of the inverter on this phase.

tvbshelly Posted August 4 Share Posted August 4 Basically, the firmware is currently doing it "almost right": unfortunately only by adding up (integrating) all negative phases and all positive phases in the measurement interval and then adding them to the respective counter/meter (instead of simply adding/integrating across all phases, then only adding it to correct one counter/meter depending on the sign). This is how it should be: Add up/integrate the power across all phases and count it as a consumption (consumption meter) if the result is positive and as export (export meter) if the result is negative. That is balancing. A simple if statement is probably enough to implement this - just a guess đ @Dimitar 4 1 Quote Translate Revert translation?

Homer Posted August 17 Share Posted August 17 (edited) Hi Everyone, I have a "parallel" setup with one Shelly 3EM at my grid source. It shows negative values when my PV system overproduces, and this is correctly reflected as "generating" on the energy tab of the web interface. Iâve installed a second Shelly 3EM directly on the trunk of my PV system (3-phase). This one shows positive values, and I've set it as the "generating source" as recommended. However, Iâve excluded this Shelly from the consumption settings in my account, so the energy tab numbers look more accurate. Is this the correct approach, or do I need to reverse the measuring clamps on the PV Shelly to get accurate values? Reversing them is difficult due to their location, so I would appreciate any advice on setting it up correctly before going through the trouble of changing them. Best, Homer Edited August 17 by Homer adding additional context Quote Translate Revert translation?

Yes, this is the recommended way for your installation: measure PV as positive and set the device type of the PV Shelly as the "generating source". Quote Translate Revert translation?

I'm not using the Pro version like you showed in your screenshot, and Iâve already applied the latest firmware. Does this feature only work with the Pro version?

Members thgoebel Posted August 17 Members Share Posted August 17 As a last resort swapping the pins of the current clamps would be possible: Either via pulling the pins out of the cage or with an adapter cable. Such a cable (three a required, one for each clamp) could I provide for 2,50⏠per piece. Shipping extra⊠Please send PM if interested! Quote Translate Revert translation?

It's now back to the initial setup described, and everything is working. I've also found a better spot in the switchboard that provides easier access to the CTs and makes switching simpler if needed. 1 Quote Translate Revert translation?

ihor.bardakov Posted August 20 Share Posted August 20 hello  Until today, a system with three counters worked for me one 3em two PM mini Shelly 3em is responsible for the state network and two Shelly PM mini are defined as generating units one PM mini for Ecoflow powerstream and another PM mini to count energy for charging batteries but now my two PM minis don't show up and the system about the balcony solar station doesn't work anymore what to do - what kind of update is it that broke everything? 1 Quote Translate Revert translation?

I read that another users have the problem only with PM Mini Gen 3. The problem is that PM MIni Gen3 isn't visible in the PV configuration.

tvbshelly Posted August 21 Share Posted August 21 Feedback on the PV Setup Alpha v.0.0.4 dashboard: My setup: 2x Shelly PRO 3EM, Parallel I really like the new overview. The data displayed is also correct (compared to my "trick" with the separate room for both PRO 3EM to calculate self-consumption (right part of screenshot)). In a large browser window, the graphic is pulled very far apart. I think this makes it a little less easily readable. Â Quote Translate Revert translation?

tvbshelly Posted August 21 Share Posted August 21 (edited) Unfortunately, the graph is still wrong - but the balancing issue is well known: The house consumption is correct, but at 6 a.m. no energy was being exported to the grid or consumed from the grid. The entire house consumption came directly from the PV battery. As you can also see, export and purchase from Grid are virtually the same, i.e. zero in reality. Here is the comparison with the self-consumption room trick: House consumption is the difference between Consumption and Generated (669 Wh minus 189 Wh = 480 Wh) and the same as in the picture above  The values from 10 a.m. for comparison: At that time, it was almost exclusively export to the grid, as there was a large PV surplus. The values are therefore âmore accurateâ here:  Edited August 21 by tvbshelly Quote Translate Revert translation?
