Flip over the PANELS on the roof. I think they're matching units, of different age. Siemens had a habit of changing up their markings. I would guess the're 50 w PANELS, and should have close to matching voltage/current capabilities. The ASC isn't any great charge controller, but if you already own it, I'd use it to get your feet wet. After all, it's only 150-ish watts. Same deal for the battery, 90 Ahr isn't that big, but the price is right. It'll also teach you real quick about battery conservation.
Edit to add: The battery posted here is just barely bigger than the Les Schwab Group 24 you've posted in the other thread. I wouldn't run them together, due to differing charge characteristics.
PS: They're panels, not chargers. Not even when used as a battery charger.
