LCD Backlight Display: Equipped with a clear-definition LCD display with backlight function, offering simple and convenient operation. Multifunctional Design: 1600W PV panel multimeter supports auto/manual detection mode switch, measures PV panel maximum power point power, maximum power point voltage, maximum power point current, and open circuit voltage. Automatic Measurement: Easy operation; when the [Auto MPPT] test button is pressed, the multimeter performs self-test based on the current power value, automatically adjusts the test interval time according to the power level, and refreshes the digital display. Manual Measurement: Press the [Manual MPPT] test button as needed; the instrument automatically adjusts the test interval time based on the current power value—the higher the power, the longer the interval—and updates the digital display. Solar Powered: Operates using solar panel power supply (not included), eliminating the need for batteries and providing an economical, energy-efficient solution. Five Protections: Includes over-temperature protection, over-voltage protection, over-current protection, reverse connection protection, and over-rated power protection. Wide Applications: Suitable for photovoltaic panel manufacturers, operators, installers, users, and solar energy enthusiasts.
