How do the Solar Controller Work?
A Solar Controller, or solar regulator is similar to the voltage regulator in your car. It regulates the voltage and current coming from the solar panels going to the battery. Most “12 volt” panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging. Most batteries need around 14 to 14.5 volts to get fully charged.
Not always, but usually. Generally, there is no need for a Solar Controller with the small maintenance, or trickle charge panels, such as the 1 to 5 watt solar panels. A rough rule is that if the panel puts out about 2 watts or less for each 50 battery amp-hours, then you don’t need one.
For example, a standard flooded golf car battery is around 210 amp-hours. So to keep up a series pair of them (12 volts) just for maintenance or storage, you would want a panel that is around 4.2 watts. The popular 5 watt panels are close enough, and will not need a controller. If you are maintaining AGM deep cycle batteries, such as the Concorde Sun Xtender then you can use a smaller 2 to 2 watt panel.

1. Intelligent control is realized by using microprocessor and dedicated control calculation.
2. Four load working modes:Pure lighting control,lighting control &timing control, hand operation and debug mode.
3. Scientific management of battery:as it is overcharged,the battery will get booster tension charge.As a result compulsory maintenancevis available for the battery.In normal working state,the direct charge and floating charge are both available,so that the battery life-span is increased.Bsides,the adoption of high precision temperature compensation makes the charing more accurate.
4. Comparing with the charing loops using diodes, the one that adopts double MOS series circuit control makes the voltage loss dropped by 50%.With the PWMfuzzy control in charge efficiency is improved a lot
5. LED screen shows the working state of solar battery ,storage battery and load.LED shows the adjusted parameter.In this way, users can learn the operation state in ream time.Besides,there are various choices for parameter, users can select the proper working mode based on the different conditions.
6. Various protections include over-charge,over-discharge and over-load,as well as unique electron short circuit protrvtion and connection-reverse protection.All the protections are harmless to any parts and fuse,fuse only as the end protection of a controller itself to protect the amount of internal short circuit damage.Non wire jumpers design improves the reliability and durability of the products.
7. Industrial-grade chips and precision components are sdopted for all the controls.Therefore,the controller performs well in very low and high temperature,as well as humid environment.At the same time,with the use of crystal timing control,the timing function of controller is much more reliable.
8. Using large-diameter wire terminal,can fix the wire which max size is 6mm2
9. Parameter is set to power-down save function,the system model and control parameters,and other important data are stored inside the chip,after power is not lost,to make the sdjustment more convenient,more reliable system.
10. Using 2digital LEDs display and settings,one-button operation to complrtr all of the settings, intuitive and easy to use.
