tripped Posted September 6, 2012 Report Share Posted September 6, 2012 I have some questions I was hoping someone would help me work through. I am building an outdoor fountain that I want powered by a solar cell. Can I run the solar cell wires directly into the BLDC motor and have it operate only when sun is shining? The brighter the sun the faster the motor turns. Or do I need more circuitry to make it work? If I do hook up a small 3.7 v 2000 mAh Li Ion battery, I need a charge controller? And what? PumpVoltage VDC - 6.0 NominalCurrent Draw: 0.27 AmpsPower Usage: 7.0 Watts Solar cellOutput Voltage: 0.5 volts (Vmax)Output Current: 3.5 Amps (Imax)Average Power: 1.75 WattsIs there any way to turn the motor on for 1 minute every hour on the hour? Miniature controller or driver of some sort? System as compact and concealable as possible. Any help out there For this one? Oh one more thing, is there a micro charge controller out there that would protect the battery when it was full by dumping the load into some LED’s or something of that nature?

Guest buzzelectrician Posted March 29, 2013 Report Share Posted March 29, 2013 hiYou can also make it store the power and make it an alternate current so the motor does not change its efficiency with the rays of sun..that may exhaust it real soon.Spam link removed by moderator Quote Link to comment Share on other sites More sharing options...

audioguru Posted April 20, 2017 Report Share Posted April 20, 2017 None of your voltages match. The solar panel produces only 0.5V. The battery produces only 3.7V and is charged from about 5V or 6V. The pump needs 6V. A battery charger does not dump power when the battery is fully charged. It simply turns off the charging. Quote Link to comment Share on other sites More sharing options...

I noticed the same that the volts don't match. Quote Link to comment Share on other sites More sharing options...
