Basic Info.
Product Description
Solar controller is mainly used for solar off-grid power generation system, can automatically control multiple solar panels for battery charging equipment, coordinate the efforts of solar panels, battery, load, monitoring, charging status, display panels for battery charging current, voltage and battery, can effectively prevent the battery overcharge, the function of the meter and the short circuit.
PWM is the pulse width modulation, refers to the digital output of the microprocessor to control the analog circuit, is a digital coding method of the analog signal level.Digital control of analog circuits can greatly reduce the cost and power consumption of the system.
The electrical structure of PWM solar charge controller is relatively simple, mainly consists of a power main switch, a capacitor, a drive and a protection circuit, which is actually equivalent to a switch, the component and the battery are connected together, the voltage of the component will be pulled down to the voltage of the battery pack.
Product Features:
1) voltage automatic identification system12V/24V or 48V automatic identification
2) humanized LCD display and double bond operation man-machine interface
3) full use of technical data set and modify
4) efficient smart PWM three charging
5) can choose the loading control template, in the evening time can be seton the street
6) reliable protection: overvoltage, short circuit, overload, overcharge, overdischarge protection function
7) accurate temperature compensation, correct charging and dischargingvoltage, automatically prolong the service life of the battery
8) input terminal positive and negative extreme reverse connection protection
9) power set parameters of the controller can be reset to default.
