Great for making sure a solar panel is putting out the appropriate current, voltage, and most importantly wattage. This meter is better than using the ISC and VOC readings from a multimeter as there are times, though rare, when those numbers come back good but when under load the panel under performs. This device will actually perform an MPPT sweep on the panel to determine its max power. Temperature and light intensity must be controlled or accounted for but this removes a lot of variables from testing. Comes with MC4 and Alligator clips for testing.
