LCD Photovoltaic Panel Power Supplys Solar Panel Multimeter MPPT Tester EY800W Features Automatic MPPT detection: When the AUTO MPPT test button is pressed, the instrument automatically adjusts the test interval according to the current power value and refreshes the digital display. For example, when the power of the solar panel is 100W, it is refreshed every 5S, and when the power is 300W, it is refreshed every 15S. Manual MPPT detection: When the manual MPPT test button is pressed, the instrument starts to scan the maximum power point and refresh the digital display.Open circuit voltage detection: When the VOC test button is pressed, the voltage of the solar panel will be displayed in real time. Multiple protections: over-voltage protection, over-temperature protection, over-current protection, over-rated power protection.Photovoltaic panel power supply mode, no need for additional power supply, easy to use. Over temperature protectionWhen the multimeter reaches 60, the multimeter will display "over temperature", please wait for cooling before use. Overvoltage protectionWhen the input voltage of the multimeter exceeds 60V, the multimeter will display "overvoltage", please use it within the voltage of 12~60V. Overcurrent ProtectionWhen the input current of the multimeter exceeds 20A/35A, the multimeter will display "over 1 current", please use it within the current of 35A. reverse polarity protectionWhen the positive and negative poles of the multimeter input are reversed, the multimeter will not display, please check the input polarity in time. Over rated power protectionWhen the input power of the multimeter exceeds the rated power, the multimeter will display "over rated power", please disconnect the solar panel in time and use it within the rated range.
