Here is the link to the Panel https://4thdsolar.com/collections/solar-panels/products/fx18l-80-watt-semi-flexible-panel. Does victron have a MPPT to deal with this Panel? they system is charging is 14.4v.

@Sam Salwei unfortunately this panel's voltage is too low to use with an MPPT; the MPPT requires vbatt+5v from the PV array to start charging a battery. Have you considered adding another panel in series to get your VOC up around ~23v?
Since your panel is generating lower voltage than your battery resting voltage, I don't believe even a PWM would do the job here, unfortunately; there are other manufacturers who make single-panel boost controllers for exactly this type of use case, but that's not Victron's generally anticipated use. You could probably cobble something together using a DC-DC converter before the MPPT to get your voltage up, but that's not a supported connection method, and then a lot of questions are raised about how the DC-DC would react when the MPPT puts a load on it... and you'd also probably end up spending more money in components trying to do that than just buying a second panel.
Long story short, I strongly advise that you get a second panel and connect it in series with your first so that you get your voltage up to a usable level.
