Solar Module Descriptions: 

Solar Power Modules (known as Photovoltaics - PV) can generate electricity for your home or business, either as part of a stand-alone solar power system, or for buildings already connected to the local electricity network.

PV systems use the most abundant energy source on the planet, solar radiation, to generate electricity. They are silent, consume no fuel and generate no pollution. They also contribute to the reduction of greenhouse gas emissions; a 2kW PV system on a house will prevent the emission of about 40 tonnes of CO2 during its projected 30 year lifetime. Furthermore, the use of PV will reduce your electricity bills and exposure to fluctuating and steadily rising electricity prices.

FAQ

 

Q: What kind of loads can I run on PV?

With a correctly designed PV system you can power almost any electrical load. However, as the load size increases the expense also increases. Loads like hot water heaters, air conditioners, room heaters and electric stoves should be avoided. The added cost of trying to power loads like these is very cost prohibitive. If these loads have to be powered it will be a lot less expensive to change the appliance to use an alternative fuel type like propane.

Q: When do I need a charge controller and why?

The safest way to figure out if you need a charge controller is to take Battery Amp Hour Capacity and divide this by the Solar Panel max. power amp rating. If the quotient is above 200, you don't need a controller. If the number is less than 200 than you need a controller.

For example if you have a 100 amp hour battery and a 10 watt panel, you take 100 and divide it by .6 (600mA) and you get 166.6. Since this is less than 200 you need a charge controller. If you have a five-watt panel in the above example you take 100 divided by .3 (300mA) and you come up with 333.3. Since this is larger than 200 you do not need a charge controller. However you still need a blocking diode, to prevent the battery from discharging to the panel at night. So as a general rule of thumb you don't need a charge controller unless you have more than five watts of solar for every 100-amp hours of battery capacity.

Q: What is PV & how does it work?

PV stands for photovoltaic. Photo = Light and Voltaic = Electricity. A solar cell converts light to electricity.

A solar cell is made of silicon. Computer chips are made of this same material. Basically, when light strikes the surface of a solar cell some of it is absorbed into the silicon. This light energy bumps the electrons loose and causes energy to flow.

By packaging approximately 36 solar cells together a solar panel or a solar module is created. When you have more then one solar panels you create a solar array.

Q:What is the meaning of the 30A solar controller?
The maximum current is 30A
Q:Solar controller can not charge what is the reason
Are charged control point voltage: direct charge after the end of the battery will be charged and discharged controller for some time, so that the voltage naturally fall, when the fall to the "recovery voltage" value, will enter the charge state. Why are they designed? That is, when the direct charge is completed, there may be individual batteries "backward" (terminal voltage is relatively low), in order to pull these individual molecules back, so that all the battery side voltage is uniform, so it is necessary to high voltage with moderate Of the current and then charge a small meeting, we can see the so-called charge, that is, "balanced charge." Are charged time should not be too long, usually for a few minutes to ten minutes, the time set too long but harmful. For a small system equipped with two batteries, it is not meaningful. Therefore, the street lamp controller is generally not full charge, only two stages
Q:Solar panels for solar panels
Using the series PWM charging the main circuit, so that the charging circuit voltage loss than the use of diode charging circuit reduced by nearly half, the charging efficiency of 3% -6% higher than non-PWM, increased power consumption; over discharge recovery to enhance the charge, Normal direct charge, float the automatic control mode so that the system from a longer life; at the same time with high precision temperature compensation; intuitive LED LED indicates the current battery status, allowing users to understand the use of the situation; all control all use industrial chip ( Only with I industrial controller), in the cold, high temperature, humid environment to run freely. At the same time the use of crystal timing control, timing control accuracy.
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: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:Solar controller red light flashing
Look at the flash of red light shows what is the logo, the general controller should be a bad flash line
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: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.
