During installation, the water surface must be above the sensor. When the water surface drops below the sensor position, the pump stops immediately. The pump will resume operation 10 minutes after the water level covers the sensor again.\u003c\/p\u003e\n\u003cp\u003eSolar direct applications should use a nominal panel size of 340 watts for standard applications, but larger 72 cell panels can be used for peak performance and a wider window of operation.
