[RE-wrenches] Solar pumping stormwater

[Windy Dankoff]

Dear Mac,

For a non-battery, PV-direct system, you will need to shop for an appropriate AC pump, and an AC pump controller, AKA "pump inverter". 3-phase is ideal for this because it's better for this variable-speed application. However, this power level, you probably will have to settle for 1-ph. There is only one controller I know that can handle 1-ph motors. But there are some limitations, so I suggest that you call the company:

Ask for Nikola. He is very familiar with applications like this, and very helpful (and funny).

Yours!
Windy

> Im looking for recommendations on solar pumps for a stormwater overflow application.  The water will be cruddy so the pump would need to be able to tolerate that, although we will do our best to mitigate that.  I'd like to be able to pump about 20,000 gallons per day or so at a head of 20'.  My preference is no batteries but we could design in batteries.
