Looks like a nice install. Mono crystal 24 volt panels, good choice. A PWM charger should work just fine. There is a lot of pro MPPT controller sentiment on the forum but your PWM controller should work very close to as well. I have a 65 watt panel with a Kyocera PWM controller. My solar system at it's best will put out 3.8 or so amps at 14.4 volts. In a full day of sun, it will do a decent job of charging my 2 group 31 AGMs. Eventually I'd like to have somewhere between 3 and 400 watts of panels on the roof. That is where the magic number of charge requirement is for our amount of use and cloudy, rainy days.
Looking forward to hearing your first performance report.
