Packaging & Delivery of L-Series PV Controller
Packaging: Wooden box or Customized
Delivery: Depends on the quantity or Customized
- Q:Solar controller one machine how
- You should include a charge and inverter as one of the machines. This product is also very good, but for many users is not very applicable, such as I hope to enter the input, but the output power can not meet, and configure the inverter is more waste. If your needs and configuration just right, it is still relatively easy to use. The cost of the above is higher.
- Q:The principle of solar controller
- In fact, is a power management. Solar controllers are divided into different types of applications, but are basically controlled by solar charging and battery discharge management.
- Q:What are the solar controller models?
- The controller is 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 chip on the battery terminal voltage, discharge current, ambient temperature and other parameters related to the battery capacity of the sample, through the special control model calculation, 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.
- Q:How to adjust the solar controller
- Charging and overpressure indication: When the system is connected normally and the sun is exposed to the photovoltaic panel, the charging indicator (1) is green, indicating that the system charging circuit is normal; when the charging indicator (1) Description of the system over-voltage, the treatment see the fault handling content; charging process using the PWM method, if there have been over-discharge action, the charge must first increase the charging voltage, and keep 10 minutes, and then down to the direct charge voltage, Live activation of the battery, to avoid sulfide crystallization, and finally dropped to the float voltage, and keep the float voltage. If there is no over-discharge, there will be no way to enhance the charge to prevent the battery water loss. These automatic control processes will allow the battery to achieve the best charging effect and to ensure or extend its service life.
- Q:A solar controller 12v20A battery 12v 20A Will the need for a few watts of solar panels can be normal charge
- In fact, there is a need for greater power loss. If half a day filled with more than 120w, analogy.
- Q:What brand of solar controller is good
- In today's solar industry, brand-name products in terms of quality to after-sales service, are guaranteed. And consumers want to compare through their own observation to choose, there are some difficulties. Such as the key components of solar water heaters is the insulation of the tank and the material and thickness of the liner steel, only the water tank can be destroyed before the amount of liner thickness and material. There is the quality of the vacuum tube, these things even if our industry people, without destroying the product, do not use precision instruments in the case, can not be identified
- Q:How the inverter is connected to the solar controller
- What are your requirements, the inverter is the battery
- Q:What is a solar controller?
- Solar controller uses high-speed CPU microprocessor and high-precision A / D analog-to-digital converter, is a computer data acquisition and monitoring and control system. It can collect the working data of the PV station in real time, obtain the working information of the PV station at any time, and accumulate the historical data of the PV station in detail, and provide the accurate and reliable evaluation of the reliability of the PV system design and the reliability of the quality of the inspection system Full basis. In addition, the solar controller also has a serial communication data transmission function, can be a number of photovoltaic systems sub-station for centralized management and remote control.
- Q:Solar controller water level display is not correct how to do
- Re-adjust the water level to control, choose their own water.
- Q:How does the solar controller set up Sheung Shui?
- Press and hold the warm water temperature button for 3 seconds, hear the "drop" after the sound, the display temperature of the two digital and "regular heating" indicator light began to flash, press the heating water temperature key to set the time heating time The Set the time in Beijing plus the set number of hours is the timing of the heating time, such as set at 10 am, regular heating at 4 pm every day, then set the number of hours 06 (range 00-23), wait 5 seconds to automatically save the exit "regular heating" light is always bright, the heating effect of the deadlock, after 4 pm every day will automatically heat up regularly. Cancel the regular heating, according to "heating water temperature" between 3 seconds, hear the "drop" after the "regular heating" indicator off, the timing heating function is canceled.
