  1. Guillermo

    Works with 220v?

    • circuitsetup

      Yes it does. You just need to calibrate your AC transformer to correctly measure voltage. We do not stock 220v AC transformers.

  2. Key

    If I purchase this kit, what else do I need to do?
    Do I need to do any programming?
    Can it measure energy production from Solar? (Can this read negative reading from meter?)

  3. Christ

    Hi,
    from where can i buy the complete kit. From this website or crowd supply? If I connected to only 1 phase can I disable the second AC transformer?
    Thanks
