The controller is pretty cheap but will work well enough to get you started. I'd replace it with an MPPT controller if it fails down the road. Don't expect much help from Renogy if anything fails, they have a poor warranty reputation on the net. The PV panels are fine, a lot of people are happy with Renogy panels. I think your meter only measures current in one direction so it won't keep track of the energy going back into the battery from the PV panels. You'll have to reset the meter every day after your battery is charged (PITA). I'd use a true battery monitor instead. The Aili Battery Meter would be easier to use as it tracks current in and out of the battery so you don't have to reset it every day.
That battery is pretty large for your use case, I would get a 100A-hr battery to begin with and then see if it's big enough. You can add another battery after a year if it's too small. You can't add batteries later with lead acid but you can with LiFePO4.
Will Prowse on YouTube has reviewed the Ampere Time batteries, I'd watch a few of his videos to see what they are like as I don't know anything about that brand.
Hope this helps,

I bought all my Victron stuff from Continuous Resources. They are an authorized dealer, match Amazon prices, have free shipping and offer a 10% discount code of DIY10. I saved a bunch of $$$ using the discount code.

You can wire your panels in series with the MPPT controller, there are positive and negatives galore on the two different connections.
