Renogy and Victron MPPT Controller?

Q&A and troubleshooting

I recently converted my RV over to Victron. I purchased the Multiplus ii, bluetooth 500 amp shunt, MPPT Controller, and the Cerbo GX with a screen. The motorhome is already setup with solar, so I simply replaced all my other components with this and am up and running.

We are in the middle of another project where we are adding solar to a box trailer that is often pulled with the motorhome. The box trailer will have its own separate MPPT controller and will assist the motorhome solar setup when needed. That being said, I’m considering using my existing Renogy MPPT controller for the trailer. But my question is what will that do given all the great data I currently get from the Victron setup? Is there a way to ensure that Victron captures that extra solar power coming in or do I need another Victron MPPT controller to accurately collect the data?

You’ll need a shunt (smartshunt) to measure the solar coming from the Renogy MPPT or indeed replacing the MPPT with a Victron one.

To add to what @Skipper suggested, if you want the Renogy data in general, it is unlikely that Victron will read it. But depending on the exact data you need and kind of gear especially batteries you have, there might be other means to get the same data.

I think this is the best choice…. Didn’t even think about a 2nd smart shunt! Thank you! This is probably the route I’m going to take. Thanks!
