This solar panel multimeter can test the maximum power point and open circuit voltage of photovoltaic panel. The power supply method of solar panel is more environmentally-friendly and energy-saving, and it requires no additional electricity. With multiple protections, this multimeter is safe to be widely used in many fields.Features:Auto MPPT Detection: When pressing the AUTO MPPT test button, the instrument automatically adjusts the test interval time according to the current power value and refreshes the digital display. For example, when the power of solar panel is 100W, refresh once every 5S.Manual MPPT Detection: When pressing the manual MPPT test button, the instrument starts a scan of the maximum power point and refreshes the digital display.Open Circuit Voltage Real-time Display: The open circuit voltage will display on the large LCD screen at any time, giving you a better experience.Large LCD Backlight Display: The screen adopts large LCD with backlight for easy reading no matter in the day or at night; you can turn on/ off the backlight as you like.Multiple Safety Protections: Over-voltage/ over-current/ over-temperature/ over rated power protections ensure safe use.Wide Application: This multimeter can be widely used by PV panel manufacturers/ distributors/ installers/ users and anyone who is interested in PV panel.2 Models Optional: EL400B/ EY800W.
