    Hello Mario,

    Thanks for writing in.

    To prevent  battery from feeding back, you can add diode at the output.

    We are sorry we don’t have step-by-step instructon for this usage.

    Regarding to connection and setting, please kindly refer to this instruction https://images-na.ssl-images-amazon.com/images/I/C1QIs1zApZS.pdf

    Hope it can help you.

    in reply to: Model 5310 Power Supply/UPS loss of output on AC voltage restore #30211

    Hello StinkyVoltz,

    When AC power is restored, if output is normal (no zero ouput),  that means it is normal.

    Output votlage from battery and AC power is different, when  switch, it may cause voltage varies.

    Best regards.

    in reply to: AC 80~260V / 100A lcd digital volt/amp meter #30200

    Hello Marc Imerone,

    Thanks for writing in.

    We have two AC 80-260v meters, so we are not sure which one is correct.

    200123

    200071

    It’s regretted both of them don’t have outdoor version. It’s better not to extend wire, which may have influence on measurement.

    Any more questions, please let us know.

    Best regards.
