Smartsolar MPPT 75/15 + 100W panel (18v/5.5A)

Hi braintrust

Absolute beginner here. I bought 100W solar panel off amazon to trickle charge my 100AH Lifepo4 battery when im out camping for a few days off grid. Ive been told to use an MPPT as it has the ability to charge Lifepo4 batteries

The panel outputs 18v and 5.5amps, just confirming this will work with the MPPT

Thanks in advance!

Should work with a PWM controller.
