At 675W, I would hope you could get some charge out of that! Nice setup. I only have 2x100W renogy panels with their basic pwm controller (more craigslist toys I couldn't pass up).
Would like to go to 4x100W with a small 30A MPPT. Sadly 2 golf cart batteries is all I can drop in without major work (and some idea of where to put them) or just crazy $$$$$$ for AGM unvented.
Tempted to do the bigger solar anyway - even if a bit oversized for 225aH of batteries - just have excess capacity for the more cloudy or shady days.
For now I'll see how the 200W + pwm works as I get used to things.

200W should put you at around 11 amp/hour charge rate, maybe 12. Get your self a charge controller, and measure the amp hours actual output to your batteries while pulse charging.
RC charge meterPut it in line... also, you may want to get a charge controller that has adjustable voltage for bulk and float charging of your batteries. Something that you can get 15.0V or 14.8V out of, to get your battery closer to 100% charged every 24 hour period.
