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.

 

 

Attention:

1. Please be sure to use this product within the rated voltage and current power range.
