JKB- You are a controls FREAK! And I mean that as the highest form of compliment!! I have read your post at least 5 different times and each time I learn something new. Thank you!

I really wasn't sure if I could use the LCB as the power source with the motor speed controller (remember I'm a mechanical guy). I realize 24V would be a better choice but I had 12V stuff already so I started there. Still not sure how my current electronics will hold up. You got any ideas about longevity? (I know there are a lot of all depends here smile )

For direct pumping, pretty simple...use the power now because once the sun sets its gone until the next sunrise. Anybody can do it with 600W of power and $4,500...I want to do it with 150W and $800 grin
