Victron MPPT Question

[gherkin12]

Evening all
Quick question, we've got a pvlogic dual 60w solar system on the roof of our t6.1 mated to a pvlogic 10a pvm (I think it's a pvm, basically not a mppt). Now my wife is very data driven and would like to be able to see what is going on and has been looking at a victron smartsolar mppt, however I've no idea which one I would need.

This is what I have atm (but two of them)

60W Flexi Solar Panel Roof & Deck Top Kit | PV Logic

Our 60w flexi solar panel roof & deck top kit allows the solar panel to be professionally fitted to the roof of a caravan, motorhome or yacht.

The specs of the panel say a 10A controller is required, but as there's two, they could be wired in parallel, doubling the max current to 20A therefore a Victron 100/20 is a safe bet. (If they're in series you could get way with a lesser rated one.)

A 75/15 or 100/20 smart should see you sorted.

The smart solar is the BT version.

Ah OK, so this is the thing that was confusing me slightly, I get there second number was the A but tje first number is that the wattage from tje solor array?

Also would one presume that from the picture below, the 4 cables going in on the left hand side (2 x +ve 2 x -ve) would indicate that it's not in parallel? (really need to obtain a wiring diagram from the convertors) and you'd be able to do the same with the victron?

On victron the first number is the VOC open circuit voltage.

So max voltage the panel can produce, off load.

And the second number is the max current the unit can deliver ie charge rate to the battery.

So the 100/20 is 100v input max and 20A charge max.

Your wires....


Looks like..

You have two Solar panels connected in Parallel on the left (blue mark)... Two pluses together, two begs together.

And the leisure battery connection on the orange + and purple - ..(red mark)

Ah so they are in parallel, OK that's good to know, thank you

As you have the cable ends of both panels easily accessible, you can wire them anyway you like. There are advantages and disadvantages of both ways, i.e. series or parallel.
