I have a similar setup. 120w portable (10m cable) solar panels, 50L waeco, 2 strip lights and a few "toys" off usb charging. I have no other charging methods and we almost never use 240v. The panels charge my battery, even in some shade, and I've never had any problems charging the 120A AGM.
The longest camp was for 5 days, and I am convinced that your panels are only as good as the regulator (buy the best you can afford)
