Good job, stirlingtech!
The pump was planned to use for a fish pond at a Daycare for children here. The fish pond worked hard "as they could" along with me and staff in building it in the playground next to a garden. It's small"(30gal) but the fish we put in it were selected by kids. They make it a point to be sure we feed them every day. However, I know that the pond is potentially too small to allow enough oxygen to circulate naturally for about 30 fish. As the fish grow I know it will become more and more difficult for them to possibly breathe under water. It would break those kids heart to see them die. I don't want them to whiteness that.
I received my pump very fast in good condition and installed it effortless. The reveal to the kids was a great joy and happy moment for both them and all of our staff. It brings great comfort to them to know that the fish can breathe a little easier in our pond.
My only concern is that it operates properly with the solar panel. I'm not sure if it works continuously "Switched in the ON" position while the battery is in it. Or does the sun keep that battery charged. It's great that there is a user manual inside the package about the product and how to use it.
I switched "ON", the solar pump start to work continuously, it hasn't stop in day time. Because there is power inside the battery, and also the sun can charge the battery while the pump working. The solar panel transfer the sun to power and charge the battery, and battery can store some power.
Even when the day turns to dark, the solar pump can work extra 1hours by the power from the battery. And it get be charged again in the next morning.
