Pls note the connection ways:
Connect the battery first, Connect the battery first, Connect the battery first,
then connect the solar panel.
Friendly Notice from a professional factory engineer!!! 30A is maximum working current.
It will be better below 30A working current. It will have a long working life!

Function:
1. Always Keep The Battery on Fill Voltage Condition.
2. Prevent The Battery from Over-charging.
3. Prevent The Battery from Over-discharging.
4. Prevent The Battery from Reverse Charging to Solar Panels During Nights.
5. Reverse Polarity Protection for Battery
6. Reverse Polarity Protection for Solar Panels
7. When The Battery Voltage is Low, The Controller will Auto Cut Off The Load from The System. If The Voltage of Battery is Back to Normal And The Load Will Restart Working.
8. According To The Battery Voltage Grade, The Controller Can automatically Set Charge-off Voltage, The Load-off Voltage, The load- Restore Voltage. (The Parameter Is Default Under 25℃ condition, Locked By The CPU Procedure, Cannot Adjust.)
