Pond Aeration question
I want to use a brushless 24v DC pump (that says up to 60v is ok) for pond aeration (small pond, maybe 60' diameter, 8' deep). I'd like to simply connect a couple of 175w panels (30v) in parallel to the pump leads, and when the sun shines, let it pump. Anyone done this ? Question in my mind is would is would it harm the pump if the power output of the panels is near nothing at first and last light of the day ? I'd prefer to keep it simple, no batteries for buffer, no charge controller/etc....just panels to pump.
Have a SNAP (brand) DC fan in a greenhouse I connected this way....works fine. Cloud goes over, you can hear the fan RPM drop, or fade away to nothing as evening hits. Been running for several years now.
