Key instructions:
AUTO MPPT DETECTION:
When pressing the AUTO 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 photovoltaic panel is 100W, refresh once every 5S; when the power is 300W, refresh once every 15s.
MANUAL MPPT DETECTION:
When pressing the manual test button, the instrument starts a scan of the maximum power point and refreshes the digital display.
 
OPEN CIRCUIT VOLTAGE DETECTION:
When pressing the open circuit voltage button, the voltage of the photovoltaic panel will displayed in real time.
Attention:
1. Please be sure to use this product within the rated voltage and current power range.
2. Please be sure to disconnect the photovoltaic board from other equipment or loads before testing.
