I would recommend a 150/50 Victron Smart MPPT controller but you will also need to replace the Victron BMV 700 (if you have one) with a Victron 712 BMV. This is because the Smart Victron system talk to each other via Bluetooth so the BMV tells the solar controller what the true battery voltage is and this gives much better solar output. The other bonus is both the solar controller and BMV can be viewed on a smart phone, so no need to check gauges any more.
Connect the panels in 2 x 6 panel series strings, a Noark 40 amp DC circuit breaker, so you can turn the solar off if required so you can work on the system, from there to the Victron 150/50 and 6 B&S cable, a 60 amp midi fuse in the positive cable and on to the rest of the electrical system, the negative to the load side of the 712 BMV shunt.
We buy our solar panels from a wholesaler and the sticker says "solar module" so that's not a lot of help, but we also fit ones with atempower stickers on them and they seem to be ok as well. We also looked at some slimline panels at a solar place in Sheparton that looked promising to give better clearance beside air conditioners and hatches to avoid shading. Margaret took a photo of the panel label so I'll have to find out what brand they were ....
We mount them using 70mm x 25mm x 1.6mm aluminium angle, rivnuts in the panel and 6mm stainless bolts through the angle and the 25mm angle glued to the roof using Selleys Armourflex .... 2 panels per set up because that's just easier to handle, take the plastic covers off the MC4 connectors so you can fully engage them together and solder the join, slide a bit of heat-shrink over the join to protect it and you can put the possible problems of a bad connection out of mind when trying to sort problems if they ever come up.
Don't forget the diodes in the positive cables at the end of each series string.
Sorry, long post, should have warned you to get a coffee first
