Product Introduction and User Guide1. Front and back panel introduction:2. AC/DC Power Adapter:

For the area where is enough city power,users can choose utility AC/DC power charger instead of solarpanel.The input of AC/DC power charger is AC 85V~250V.The output is DC15V/500MA.For the battery of 4AH/12V,It will take about 6 hours to be full charge with AC/DC power Adapter.

3. LED and other electronic device:

This Unit can provide 4 DC12V output sockets.It can carry LED and other electronic device such as DC fan,digital device,DC TV and so on.The output DC socket is 2.1MM,and Max.output is 2A for each,But total Output is also 2A.If overload happened Controlller will cut the output,when you move the load,controller will automatically release to carry the load.

Battery capacity strip flash:

Each strip equals to 20% of battery capacity.

Note:the calculation takes fully charged voltage as 100%, and over discharge as 0%. All is based on battery voltage, not the real battery capacity.

Data updating:

Serial communication happens every 10 seconds between control module and display module, so the data update takes in 10-20 seconds.

Battery capacity AH:

AH is the accumulation of charging, each one minute will count. The data is not accurate while the charge current is too small. The min. is 0.1AH.

Charging and discharging accumulation WH:

Solar panel displaying is open circuit voltage. It can't be calculated. WH is product of battery voltage and charging current accumulation.
