Choose a solar controller which need to have a few conditions
- According to your specific application environment, first determine whether to select the charge controller or charge and discharge controller. Two applications of input and output power level, the input power is mainly solar panels, and the controller is basically in accordance with the current to count. For example, 12V system 120 wrench that should be selected at least rated 10A controller. While the actual system current 7A or so is the other security margin.s
How the solar panels with the controller
- Hong-wing HY-12 / 24V10A solar street light controller designed for solar DC power supply system, solar DC street lamp system design, and the use of a dedicated computer chip intelligent controller. Use a one-touch touch switch to complete all operations and settings. With full short-circuit, overload, unique anti-reverse protection, full, over-automatic shutdown, recovery and other full-function protection measures, detailed charge instructions, battery status, load and a variety of fault instructions. The controller through the computer core search chip on the battery terminal voltage, discharge current, ambient temperature and other parameters related to the battery capacity sampling, calculated by a dedicated control model to achieve the characteristics of the battery discharge rate, temperature compensation correction of high efficiency, high accuracy Rate control, and adopted a high efficiency PWM battery charging mode, to ensure that the battery work in the best condition, greatly extending the battery life. With a variety of work patterns, output mode selection, to meet the various needs of users.s
What brand of solar controller is good
- Above these products are also good quality, your problem is the price, which the highest? This is mainly to see the local dealer pricing, and some require profit is not high, the price is cheap; some require high profits, the price is expensive. So I put these products and then divided into 369 and so on, give you a quality reference, you go and dealers brave bargain go. Best: Tsinghua sunshine (in addition to fast music series), Emperor Ming, billion Canon. General: Hua Yang, Qunlang, Sang Le, brilliant, sun rain, four seasons Mu bad: Tian Pu. Disclaimer: I am not above any of the company's employees, our company's products can also, the price is cheaper than them, our retailers do not know where you are there.s
Solar controller can not charge what is the reason
- Overdischarge protection Termination voltage: This is better understood. Battery discharge can not be lower than this value, which is the provisions of the national standard. Although the battery manufacturers have their own protection parameters (standard or line standard), but ultimately to close to the national standard. It should be noted that, for safety reasons, the general 12V battery over the protection point voltage plus 0.3v as a temperature compensation or control circuit zero drift correction, so 12V battery over discharge protection voltage is: 11.10v, then 24V system over discharge protection point voltage is 22.20V. At present, many manufacturers of charge and discharge controller are used 22.2v (24v system) standard.s
What are the solar controller models?
- This situation is best to contact the manufacturers, generally have PDF version of the manual. You can contact the manufacturer to an electronic version of the manual.s
What is the meaning of the DC load above the solar controller?
- Lamp or load class is DC DC12V / 24V / 36V / 48V, etc. If you want to AC load AC220V lamps or other, you need to add a DC-AC inverter in the middle.s
