you said that you have a fridge, and you want to make it to work in solar panel (250W) and (200Ah) batteries.
the fridge seems to be 12V DC, you can buy a MPPT controller if you want to get more effiecent system as the PWM controller is less in effiecency by 30%.
you can check the following products on Amzon

That is almost certainly not a real MPPT charge controller, and it is way overpriced for what it is. The "PV Off" setting is where charging stops and the battery goes into float. A single setting is not enough, with this controller you will always undercharge and eventually ruin the battery prematurely.
​
A proper charge controller (MPPT or PWM) allows you to set a level for Bulk charge (i.e. approximately 80% charged), Absorption charge (the remaining 20% to full) and Float charge (trickle charge once full).
​
If you are on a budget, on the cheaper side get Epever or Renogy. This 30A Epever is a proper MPPT controller and is more than enough charge controller for your setup (with a 30Amp MPPT you can go up to ~400W of solar if you are charging a 12V batttery system).

With a 100W panel you don't need a 40Amp controller, or even a 30Amp controller. A 100 watt, 12V nominal panel (i.e. 18-20V PV) will produce around 5.5 amps, and a real MPPT controller might raise that to 7 amps charge to the batteries. This 15A Victron controller is vastly superior and can handle up to 200 watt solar when charging 12V batteries.
