Help with choosing MPPT Controller

[siegex]

I'm new to building my 12v Solar system

I just bought a van with a Gel deep cycle 12v system I have basically added some newer components

1. Victron Lnyx Distributor 1000
2. Victron smart shunt
3. 3000w inverter with 250a T Class Fuse (should it be 350a?)

I am having some problems with trying to match a Victron MPPT to the existing Solar panels (2×100watt)

I don't know how to calculate the mppt

I have added some photos

1. Panel specs
2. Wiring of solar?

Hope what I posted is clear

Thank you

Yep, but can't give you a definitive answer due to the unknown number of panels.

Array power / 14.5 = battery amps.

4 panels, 400W / 14.5 = 27.6A.

A 100/30 controller would do you nicely.

2x100w panels

At two 100w panels with Victron you have several choices…
(Get the SmartSolar ones- not blue solar)

A 75/15 is the cheapest and it handles 220watts.

A 100/20 gives you the option of adding a third panel.(290watts).

There is not a lot of cost difference.

Here is the spec sheet.

Good Luck

A carry out panel is a good option if roof space is limited.
