This product is a new-generation solar charge and dis-charge controller for lead-acid battery. 
The product includes but is not limited to the following functions and properties:

• LCD displayer

• Excellent heat balance design and natural air cooling;

• 4-stage charge period management(EQU, Bulk, ABS, Float)

• Temperature compensation function. The controller can automatically adjust the charge parameters of battery by environment temperature to lengthen the service life of battery.

• Sophisticated electronic protection production, including overcurrent protection, load short-circuit protection and low-voltage protection.

• Comprehensive and reliable load control mode can identify the day and night.

• Well-designed charge loop can effectively improve the efficiency of charge and discharge, and reduce the heat consumption in charge and discharge.
