760W System with Victron 100/20

I have 4 Rich Solar 190W panels and I bought a 100/20 Victron MPPT.

I'm planning to connect the panels in Parallel (2) and Series (2)

My Amps total 18.6A for the system and 40.8V connected to two 12V batteries in parallel.

My question is related to the Nominal PV Power specification in the manual for a 12V system that says 290W.

Is this a concern? Is my MPPT within the specs for a 760W system connected the way I'm intending to connect it or should I buy a bigger MPPT controller?

On a 12V battery you will get 240W nominal power and 296W when the actual battery Voltage is 14.8V.
You can use a 100/20, it will work, but it will self limit to 20A or 240 - 296W depending upon the actual battery Voltage at the time.

A 150/60 would be best suited to the ammount of PV power that you have.
