WS400A Photovoltaic Panel Power Supplys Multimeter Solar Panel MPPT Tester Open Circuit Voltage Troubleshooting Utility Tool (Standard)

This solar panel multimeter can test the maximum power point and open circuit voltage of photovoltaic panel, also using the photovoltaic panel to supplys power. With the portable design, easy to hold. Come on and try it, it will not let you down.

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, when the power is 300W, refresh once every 15S.
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 detection: When pressing the VOC test button, the voltage of solar panel will displayed in real time.
Multi-protections: over-voltage pro-tection, over-temperature pro-tection, over-current pro-tection and over rated power pro-tection.
Photovoltaic panel power supplys mode, no additional power supplys required, easy to use.
