Smart Solar MPPT 100/30 - No watts showing on monitor or app

Just installed a smart solar 100/30 and BMV-712 monitor in my Four Wheel Camper. I'm not showing any watts coming in from the panels and I can't diagnose the issue. Any thoughts? Thanks!

Disconnect the panels from the Smartsolar.

With only the Smartsolar connected to the battery, does the Smartsolar come on, can you see it and enter its settings via the Victron Connect app on your phone?


Did you connect the BMV correctly as per the manual with all your negatives going to the shunt and not directly to the battery? This is a very common mistake people make.


If you are sure you have the BMV hooked up correctly open Victron Connect again. Both the Smartsolar and BMV might alert you to do firmware updates.


When this is done, connect your solar panels again and enter the Smartsolar in Victron Connect to see if you get any charge, also be sure that you set up the Smartsolar correctly for the type of battery you have.

Another thing to do. In the app, tap on "Why is the charger off". One or more reasons why it is off will be displayed.
