    I just finished setting up this sensor to monitor my solar panels. The voltage sensors is reporting correct, but i'm not sure if the current sensor is right or wired correctly.

    This is how it is currently wired.

    Is this going to give me both charge and discharge?

    Thanks!

    @unfadingpyro I can't see your wiring diagram.

          Yes i can see your wiring now and no you are not likely to get any sort of reading with that circuit. You have the 712 wired in parallel with the charge wire, it needs to be in series instead. The load needs to be connected to the same side that the charge wire is on. So a quick re-draw of your circuit would look like this.

          Don't forget to add a fuse at the battery positive.

          The original drawing from earlier in this thread would also be ok

              Get the sensor rewired yesterday and i am now getting the correct readings! Thanks again for the help.

                @unfadingpyro Great to hear you got it all working. Always a good feeling when a project comes together :)

                  @Boots33 hi. Now, i'm working on this project for my final year project. I dont really used your overall project, i just used the concept which monitor the solar battery. I used your circuit diagram without using the transceiver and use my own code to run the project. In your opinion, is that make sense to you ?

                    @nurul-amira Yes that should all work fine. That circuit has been running 24/7 for around 4 years now without any issues.
