Ive got the same Victron regulator as you and have never had this issue or any other issue. I started with AGM's and now have Lithium and all I had to do was change the charge profile in the settings to Lithium and have had no issues, so its not the batteries causing anything. The issue is when you network the regulators together, they tend to behave as one and this is why you did'nt see anything until the sun started to hit your panels on the roof regardless of the amount of sun on your portable panel ie they both had to have sun to work properly. Whether the panels on the van are flat or not they still have only to get some sun to start showing a reading. Its nothing to do with panels putting out a certain voltage or not.

Incorrect. Go back and watch the video again. Victron regulators require a 5v difference to turn on. They even state it in their literature and put out a video explaining why they require 5v. This is Victron themselves. And when networked together they don’t act as one, they share information but operate independently meaning one can turn on (or off) even if the other one hasn’t.

Your 'network total power' is showing 0W which is odd considering you have two Victron controllers in the same network and the panels connected to the other controller don't have the low VOC issue?. Would have thought it should be showing what's coming in off the other controller.

All good. The other controller hadn’t turned on yet as it was in shade. It also has a higher VOC so will always turn on.

@@gettingtheretravel The issue you related is not confined to only Victron controllers. The problem is the solar panel manufacturers who make and market various panels, portable and otherwise for camping and leisure have not caught up with Lithium battery uptake and the need for an Mppt controller vs pwm controllers which as far as I'm aware there still isn't any with a lithium profile. So, panels in the said market segment are still made to cope within the very small voltage pwm controllers can handle and such cheap rubbish controllers are still generally provided with the panel as an included cost that a lot of us no longer need and don't wish to pay for. You could tap an alkaline 9v battery or such in the line between the panel and Victron controller with a switch to get the controller to turn on sooner in such a low VOC situation but ultimately in modern systems 12v panels unless they're in series are becoming near on useless and don't allow an Mppt controller to do very much with converting higher voltage to extra amps. It's 5:45pm here where I am now and near dark. Two remaining 12v panels I still have now in series are still producing, and showing a PV voltage of 19v from their combined VOC of around 44v which means if they were not in series they would already have been too low in voltage output for the Victron controller to work and produce anything from them about an hour ago. In short it's about time that solar blankets etc were made with a much higher VOC and lose the antiquated 12v label.

Are your portable panels and roof panels hooked together in series or parallel or deployed separately, one string at a time?

They are separate with their own regulator. The good thing with Victron is they can be networked together to overcome any issues of having separate regulators.
