How do I get my R.O. to automatically fill up a 100 gal reso and kept it full.

I want to kept a 100 gal back up reso full of water so i can use it in my garden when I please. Instead of just waiting to fill up 40 gal reso all day. How can I set up my R.O. to fill up and shut off automatically when full ?

Float valve.

I have 2 of these

They work great and have a float valve and a float switch so that both have to "tell" the system to turn on.

It is complete with a 12v transformer/wall wort and uses 1/4" plastic tubing so if you are using ro/di it is super easy to connect. Otherwise you will need fittings to adapt.
