Read solar panel

    Hi everyone,

    Offgrid solar

    I have 2x130 w, Triron 4210n charge controller (previously I have another from Offgridtec), Sealed Battery 101Ah, 3 different converter ( I use them one at the time in summer garden) and several digital watt metering devices.

    They working good and they ar in the garage.

    What I like to do is monitoring the panels from inside the house wirelesly and continuasly with Home Assistant for example...

    - A I got a eBox-wifi-01 from the Triron 4210n charge controller and connect to PC with Epever Solar Station Monitor v. 1.95 also working quite well but it is not convenient because it needs a PC continuously and as soon the pc restart you have to reconect and etc. just a problem.

    - B Now I got a "Shelly EM with 2 clams 50A" and a "Shelly 1pm"

    My question is... how can you wire anyone of them to be able to monitor the panels watts?

    1 just before the charge controller?

    2 perhaps after the controller?

    3 somewhere I don't know?

    Sorry I submited without explane n.1 picture was earlier, n.2 it was today that is very dark that is why the first digital got dark.

    All tips are wellcome.

    Thanks to anyone that knows how!

    Miguel

    Please keep up in mind that ALL Shellies with energy metering are counting AC only! Energy metering for DC current and voltage isn’t possible. Hence, you’ll have to install the current clamps and the Shelly EM at the AC (consumer) side of your converter(s).

    Thanyou thgoebel,

    so how the people shows Watts in Grafana?

    I understan I have to learn a lot, but I have to ask for what I don't know and don't undertand.

    I have offgrid solar and it doesn't produce enought for the house and I wanted to control if is it good to buy more panels of the same type I have.

    I am situated in Valbo middle of Sweden and here we don't get so much sun this time of the year.

    So now I see I was wrong when I was following someone in the internet with instrctions look the picture...

    thankyou

    I understand your displeasure well. From my perspective, this nice sketch seems to be quite loose:

    The middle box must be the fuse box of a property - obviously not off-grid. Unfortunately NOT shown was the converter: It must be located between the solar panel symbol and the fuse box. Thus, Shelly EM is counting AC current and voltage…

    So you undertand my feeling, now I undertand more.

    Also I was wandering wether to clamp the 2 wires coming for the solar panel because it shows just one line no positive +,negative - and if that was the controller or what?

    I will read more to learn what shelly devices can monitor my pannels.

    Thankyou
