Auxiliary Solar System

[Johnjayjrv]

I am looking into supplementing my "solar" system on my Trailer. Right now it has 1 - 50 watt panel with a PWM controller. I have 2 232AH 6v batteries in series for 12v. I also have an Ecoflow Delta 1300 that came with 110w panels as well as a second panel. What I am thinking of doing is using the 110w panels to charge the batteries by installing a Victron MPPT solar charge controller. If in the future I would add another 110w panel, would a 75v 15A Victron controller work or should I go with the 100v 20A model instead?

Here is a link to the panels:

It looks like this has a built in charger that cannot be connected to an SCC.

These panels connect to the Delta that has an internal SCC. The panels have MC4 connectors. I hope I'm not missing something.

Yea, I think you're right. I saw "Foldable Solar Charger Chainable" and jumped to the wrong conclusion.

@Forbisher is the expert on such things. This incantation should summon him.

Still, at $4/watt, those are mighty expensive. But they do fold down to a manageable package.
