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 panels for solar panels
100w of the battery plate count down one day also saved the estimated electricity will be able to use the battery on the market are 12v inverter is definitely 12vdc turn 220ac solar controller this thing looks like no, at most, a switch has been controlled whether Output power. The specific needs of the number of A / h battery pack you calculate it yourself
Q:What is the meaning of the DC load above the solar controller?
Can be batteries, lights, motors and other DC equipment can be used
Q:How the solar controller wiring,
Power cord - usually with the controller with a three-pin plug power cord, has a good controller; sensor line - two lines and four lines, according to the label with a plug or terminal connected to the controller; solenoid valve - Two, according to the label connected to the controller; electric auxiliary heating line - three, according to the label connected to the heating bar.
Q:Choose a solar controller which need to have a few conditions
To buy a solar controller must know the power of the solar panel and the load power to be used to determine the controller's charging current and discharge current. General solar controller are 12v / 24v automatic identification. Discharge current = load power / 12v, charge current = battery power / battery board voltage. The voltage of the panel can be set with the multimeter DC. The short-circuit current of the panel uses a clamp meter to test the current. So the battery power = voltage * current, basically know the power of the solar panel. The battery charge current will know. The current range of the controller is greater than the charging current of the solar panel and the discharge current of the load.
Q:What brand of solar controller is good
Professional to do solar energy, such as imperial Ming, Sang Le, sun rain, force Norit and so on
Q:What is a solar controller?
Can control the solar street light, the switch controller is the solar controller; domestic well-known brands should be far away power and the exchange of energy to the sun in the science and technology in Beijing; we are the power to do LED lighting business is brand goods
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:How does the solar controller set up Sheung Shui?
Solar water, heating is fully automatic operation, so users do not have to do any operation. The user can use the "SET" key to adjust the Beijing time and all-weather timing Sheung Shui, regular heating time, use ← left shift, right shift key to select the adjustment items, use ↑ to rise, ↓ down key to adjust the parameters, press "SET" Sheung Shui, heating, heat preservation, cycle key can start the corresponding function, after starting, Sheung Shui, heating, insulation, cycle icon flashing. The user continues to hold down the "SET" key to restore all parameters of the all-weather mode set by the factory.
Q:What is the use of solar controller
Perfect protection: electrical protection reverse, short circuit, overcurrent and so on.
