Hello

Question: Before I plug in my positive pv wire into unit I checked voltage . Negative probe on victron pv negative terminal screw and positive probe on pv positive wire (not plugged in) 36-37volts.

I put positive pv wire into unit and tightened bolt. I place probes onto pv terminal screws and I get no voltage. I put probe on negative pv terminal screw and probe on terminal screw for fuse no voltage. Take positive wire out of terminal and place probe on fuse and I get voltage.

Have you programmed the mppt yet?

Are you connecting live? (No DC disconnect and panels in the sun?)

Yes and yes while I was waiting I received an email from victron

Ok I had three requests on different avenues. Victron got back with this:

Reset procedure

To recover from such failure, the below reset procedure must be followed.

  1. Disconnect the PV Input terminals.
  2. Confirm that VictronConnect and the MPPT are both updated to the latest version.
  3. Power the solar charger through its battery terminals with a 12V battery or bench power supply set to 12V. Note that if the voltage at the solar charger battery terminals is higher than 15V, reset button is disabled in VictronConnect so the reset procedure won’t be possible.
  4. Make sure no error 80 to 83 is active. If it is active, power cycle the unit.
  5. Open VictronConnect and navigate to the Product settings menu. There, the PV Short reset feature is shown.

The reset worked and I am up and running
