Solar electric, with no battery, water pumping stimules our interest in effects of over- and under-voltage effects on electric motors.

Battery Charging AA, AAA, 9V NiCd and NiMH.

Hello Jack,

Are Shanghai Miaofeng solar water pumps connected directly from solar panel to electric motors?

Or to batteries which power the motors?

If connectly dirctly is over- and under-voltage protection of motors implemented?

How many volts and watts are produced by the solar panels I see in your emmail?

Please send details of solar water pumping products.
