Thomas pumps seem to do well. I run 3 on 24v solar but I don't use an inverter, I use a charge controller that regulates 24v to load side and I don't have the efficiency loss of an inverter. Highflyer is the guy to talk to on this about solar. For no more demand than I have, the charge controller works great with 2 200w panels in series with 4 12v batts in series parallel.
I can't speak for Brian, but I'm guessing he would suggest a Brat controller for a simple setup.
Membrane diffusers are probably the best quality although I have a matala Hose type (like soaker hose) 9" ring diffuser I clean with 500ppm H2O2 every year and side by side with Matala membrane I don't see much difference until late summer (but that IS the time you need efficient aeration).
