How do I hook up a Solar panel to a fountain?
I made a solar panel, it gives out 21 volts in the sun, 16 in cloud cover. I have a 200 watt power inverter and a small fountain that plugs into the power inverter.
What do I need before the panel hooks up to the power inverter, some sort of voltage regulator i assume.. Any specifics? I have a charge controller but that doesnt work without a battery, and I dont want to go and buy a deep cycle batter for the fountain.
I want the fountain to turn on when the sun hits it in the morning, and shut off when the sun sets in the evening.
Any advice greatly appreciated. THANKS!
I don't think you can do it without using a battery. The battery is about the only way to use the varying DC voltage received from the panels via the charge controller. The battery can then produce a more constant 12-14 volts DC to the inverter. You didn't say what power the panel produces. I have a small panel that produces good voltage like yours, but no where near the watts power needed to run a small pump. Even most purchased panels that cost $400-$500 may not produce 100 watts power even at peak times.
Sounds like a very expensive way to run a fountain, but it may work.
