Solar controller

Have a 250 w portable solar panel that I want to connect to a 100amp life po4 lithium battery. Will the victron mppt 75 l 15 be suitable?

Go to the solar charger product page and click on the mppt calculator.

@Suz

Assuming you are using it at 12v...

Watts is volts x amps.

250w on a 12v battery is 20 Amps. (250w÷12v=20a)

So more ideal is a xxx.20 mppt. Unless you don't mind clipping the power a bit. Or you know your irradiance and panels temps will mean you never see full power.
