Q1:Can we visit your factory?
A1:Sure,welcome at any time,seeing is believing.
Q2:How to guarantee the Quality of the products？
A2:We have established the international advanced Quality management system，every link from raw material to final product we have strict Quality test；We resolutely put an end to unQualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.
- Q:The principle of 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 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.
- Q:Solar controller water level display is not correct how to do
- Re-adjust the water level to control, choose their own water.
- Q:Solar water heater all intelligent controller how to install
- The controller can also control the electric heating. When the electric heating key is pressed, the controller turns on the power of the electric heater 7 and the electric heater operates until the user specifies the temperature. When the temperature drops below the specified temperature 3-5 degrees, the controller restarts the electric heating and heats the water to the specified temperature. Users can also specify the heating time, at a time, the temperature of the solar water tank can not reach the set temperature, the controller will turn on the electric heater, the water tank to the water set to the temperature so far. The controller also has a protective effect, and when the water level drops to a certain point, the electric heating stops until the water level rises above that point. (Usually 50% of the water level).
- Q:What is the meaning of the 30A solar controller?
- Control the superscript of the current should be in accordance with the rated current to the target, rather than the maximum current. That is: the other side of the discharge or charge when the rated current is 30A. If you explain the controller is the maximum current, the basic is substandard products.
- Q:What brand of solar controller is good
- The State Administration of Quality Supervision, Inspection and Quarantine announced the Chinese brand-name products, the entire solar water heater industry is currently only selected eight companies, as follows: force Norit Shandong force Norit New Energy Co., Ltd. billion to Shandong billion solar energy Co., Ltd. Sunrise Oriental sun rain Lianyungang City sun rain water heater Manufacturing Co., Ltd. Huayang Jiangsu Province, Yang Yang Solar Co., Ltd. Huang Ming Shandong Huang Ming Solar Group Co., Ltd. Sang music digital Shandong Sang Le Solar Co., Ltd. Tsinghua sunshine Beijing Tsinghua sunshine solar equipment limited liability company Brilliant Jiangsu Huaiyin brilliant solar energy limited company
- Q:Solar controller does not heat how to heat
- Solar controller with live heating, with no electric heating, and now your controller without electric heating, can only replace a charged heating. "Solar public welfare network" free consultation
- Q:A solar controller 12v20A battery 12v 20A Will the need for a few watts of solar panels can be normal charge
- As long as the voltage is 12V, with more power battery panels can be affected only the problem of charging speed.
- Q:How to debug a solar street light controller
- Debug mode (6 ·): used for system debugging, when the optical signal is closed load, no light signal load, easy installation and commissioning check the correct installation of the system. Normally open mode (7 ·): The power load remains in the output state, which is suitable for 24 hours power supply.
- Q:Choose a solar controller which need to have a few conditions
- The controller should have battery overvoltage protection, battery undervoltage protection, load short circuit protection, temperature compensation and other functions, select the controller to choose the quality of the guarantee. Big manufacturers big brand
