This solar on demand fountain can operate on solar and battery power when set to the on position! In good sunlight conditions, the pump will be powered by solar energy. In addition, the battery pack will be recharged via solar energy. If it is a cloudy day or night time the battery will automatically run the fountain. If fully charged, the batteries will power the fountain for up to 4 hours. When the batteries are depleted, the system will automatically switch to be powered by the solar panel, and the fountain will resume running when the sun come out.
If you have a special occasion where you wanted the fountain to run only in the evening this can be done too. During the day set the pump to the off position. Under this option the battery will store the power and not run. When you want to run the fountain in the evening simply turn the pump on and the fountain will run until the battery is depleted.
The battery generally lasts between 12-18 months, but with repeated charges and discharge cycles the battery will become less efficient and battery capacity may reduce. If the battery does appear less efficient you may try and boost charge it. In order to boost charge the battery you must leave off for 2-3 sunny days to allow maximum charge to the battery. If the boost charge does not help the battery than you will need to replace it. Contact us for replacement batteries.
Color can vary slightly on each fountain. Lighting can be different indoors and out as well as differences in computer monitors. So slight color variation is not a cause for return.
