Not clear what the 18v DC connects to--does it have battery clamps? How would it connect to a controller's input?
Says it has 3 AC outlets. So it has an inverter? It has all those adapters for your devices to go direct.
You would need a 7.5 amp eg, as a controller if this were a normal 100w 12v panel (has 6.3a ISC some of them) since in time it could get the battery up over 15v.
Suggest hands on view of this to see what connections it has --see the owner's manual--in the box (if it is not on-line somewhere) before buying.
