Perhaps we can agree that the main thing people should do is buy stuff that will last.
I may just be stubborn, but I will keep my old VFD's and other stuff running as long as possible. In fact I am replacing the alternator in my 1986 Volkswagen Jetta diesel car today. I'm welding up a new bracket so it will hold a standard alternator.
To recap.
1. Less than 10 HP and no tank = CSV (Cycle stop valve)
2. Intermittent variable loads (like in a house) = large tank.
3. High HP, Variable load (lift), and/or displacement pumps = VFD (variable frequency Drive)
4. Future = unknown, but it will be better with more choices.
