Victron 75/10 or 75/15 ?

[MrD]

Just a quick one after a search on here . Looking at installing a Victron smart mppt in my van .

Current system is 100W panel with 100Ah AGM

Want a more efficient user friendly mppt so looking at Victron Smart BT should I buy 75/10 or 75/15 ?.

Any advice people?

I would go for the 75/15 myself.

That will enable you to add a second 100 watt mobile panel if you wished.

Size wise they are almost identical with the 75/15 being only slightly larger.

Excellent , will do. Ref the mobile panel how would that “connect” into the system please?

Victron 75/15 ordered . Advice appreciated

 

[Dellmassive]

just add in a MC4 fly lead to the 75/15 controller.

then when camping, just plug it in. . . you will get power from both 100w panels.

ie:

and . . . add something like these in with your existing panel.

you might need an extension cable for the mobile Panel

That’s the mppt I have ordered from Amazon.

I assume (?) the tails linked above get hardwired into the same Panel terminals on the controller that the existing panel does currently?

 

[Dellmassive]

Yes

 

[MrD]

Thanks this is great information, might give this a go for some extra power top up and less battery anxiety if not on EHU . Cheers

The new MPPT should in itself be more efficient than the current PWM controller on at the minute, I think.

Yep. Defo.
