Which Victron MPPT solar regulator for 2X60w panels

[Pagetslady]

Hi I have bought a Victron SmartSolar charge controller the MPPT 100/20 now I have had a chance to read the manual I think perhaps I have bought the wrong one has anybody any experience of setting these up. Help needed please.

You'll be fine. For a start you bought a Victron, which is a good choice. What you've got will handle more panels than you've got - it is overspecc'ed for your job. But as far as I can tell, it will deal quite happily with your panels.

I use the 75/15 controller for 2 x 100W. That would be enough for your setup, and be £40 cheaper. If, in the future, you wanted to double your capacity to 4x60W panels, then the controller you have would cope with it, but my cheaper one wouldn't.

So - what you've got is fine. Marginally more expensive than it needed to be, but will give you the ability to expand later if you wanted to.

Thank you I fancied the blue tooth option I have 4 60W panels 2 going to starter battery through a MPPTcontroller and 2 60W Panels through a non MPPT controller which I don’t think is working correctly so I thought I would splash out and buy a Victron MPPT my batteries start and house are connected with VSR so as long as starter battery is charged
Excess goes to house battery. I have had to replace my mains charger so I bought a Victron with Bluetooth it’s great to see exactly what is going on all I need now are three nice Victron AGM 110W Batteries. It’s the blue colour I like

Your choice of controller is fine, your wiring of the panels is not. It makes no sense to connect two panels to each bank, then link with a VSR. I would connect all of the panels to the Victron and connect that to the domestic bank. If there are no significant shading issues you could connect the panels as two pairs, each pair wired in series, then the two pairs connected in parallel. Else just connect them all in parallel.
