Solar controller,also known as solar power charging and discharging controller,is used in the solar power system to regulate the solar battery get charged from solar panel and offer electricity to inverters and other loads.
Solar controller is a micro computure data clloection and detection control system through high speed CPU microprocessor and precise A/D converter. The controllr can not only get the woking information from PV station to analyse the sistuation at any time, but also accumulate the history data from PV station to evaluate if the Pv system is designed reasonable or the quality of the every components are reliable. Besides, the controller can connect and convey the communication data between many olar power systems so that users can supervise and control these systems centrally and remotely. Normally, solar controller has six voltage rates,they are 12V,24V,48V,110V,220V,600V.
1.regulate the power;
2.Communicaiton funciton: indicates; protocol communiaiton function, such as manage the admin through RS485 Ethernet and WIFI.
3.Perfect protec function: electeic protection,reverse connect,short circut,over circut and so on.
Solar controller is a tiny component in solar power system both in the size the price,but it plays an important role. It will influence the performance stability and discount the lifetime of the whole system. While a right controller will lower the price of the system to save cost.
Why we choose Wellsee solar controller ?
Now let’s make a simple comparasion between a normal controller and wellsee controller in their performance:
1. Exit voltage proteciton
Some customers notice that the solar street light will sotp shining after continious raining days when every component such as battery,controller and light works normally. Tha’t s the problem, if we choose our Wellsee controller,you can adjust the exit voltage proteciton value according to your system configuration. Please kindly pay attention that the configuration fo the solar panel should be resonable, if the electric power consumption of the street light is more than generate capability of the solar panel, the system will get hurt since the battery is always in the over discharging. Now we can reach a conclusion: we’d better set a lower exit voltage protection value to protect the solar panel from over discharging.
2. Keep the electric current output from LED light Constant
We need to make the electric current from LED light constant and limited since of the properties of the LED itself, otheraise, it can’t woks normally. A power supply which will comsume 10%-20% power is used to reach this functionality,it’s not economical. Our Wellsee controller will meet this requirement through software without any energy loss and high stability at the same time.
3. Output time period
Generally, the controller will trun off after 4 to 8 hours when the light is shining, our Wellsee controller can be set to 3 working time period according to the working condition and circumstance,you can close the controller at any time.
4. Regulate the output power of the LED light
Wellsee solar ocntroller regulates the output power of the LED light through PWM, which will modulate the duty cycle when limiting the electric current. For example, the 35W LED light connected by 35 pieces of 1W light can be set as 15W in the midlight and 25W in the twilight, making the light shining in the whole light and saving energy. The long-term experiment proves that teh LED with PWM function can creat less heat and extend life-time of the LED light.
5. Line loss compensation
It’s hard to reach the line loss compensation function since it needs the software set the system accroding the diameter and the length of the wire. Wellsee solar controller can do even in the low voltage system.
6. Heat dissipation
Many normal controller ignore the heat dissipation issue so that the heat accumultes and pipe resistance get bigger leading to the charging efficiency become lower and the life time of the whole system get shorter and even ending in smoke, especially in summer whem the outer side temperature is high. So we need to choose a good controller, Wellsee solar controller is your best choice.
