VIprecautions:

1.The test parameter error is ±0.3

2.The error of testing electrical indicators and voltage parameters is ±5%

3.The error of testing electrical indicators and current parameters is ±5%

4.Cannot throw solar cells into the fire

5.Pay attention to battery polarity when making connections

6.Solar panels must be used within the temperature range specified in the specifications

7.Solar panels must be placed in a dry and ventilated place

8.Solar panels should be kept clean if there are any attachments (fallen leaves, bird droppings, dust, shadows, etc.)

All of them will affect the performance of solar panels

9.When using, the solar panel should be fully and uniformly illuminated
