Product Description:

Product overview:

7KW Off Grid Solar Power Frequency Inverter for Solar SystemThe product is a highly stable and reliable power supply meeting high reliability requirement for power grids and network systems.Its high quality enables it to provide safe,reliable and overall protection for loads such as data centers of users,industrial control equipment ,precise medical system equipment and household appliances.It has perfect protection functions and high reliability because of a full digital vector control technology based on real-time processing by DSP,MCU and DDC.In both the pure sine wave output mode and the inversion mode,it can output a pure sine wave power supply with low distortion,thus providing the best power supply guarantee for the loading equipment of users.

Main features:

1.High reliability
  Frequency tracking,noise filtering and low distortion in inverter output because of double-conversion design

2.High adaptability
  A wide range of input frequency,which realizes stable operation of fuel generators

3.High optimal performance of the battery
  An intelligent battery management technology,which guarantees a longer battery life and decreases the times of battery maintenance.
  An advanced constant-voltage charge technology,which activates the battery to the most extent,saves the charge time and guarantees a longer battery life

4.Overall automatic protection and alarms such as output overload protection
5.Efficient IGBT(Insulated Gate Bipolar Transistor) inversion technology
      Good high-speed switching feature,large-voltage and large-current operating characteristics,and voltage drive of IGBT(The fifth-  generation IGBT has a lower saturation voltage drop and higher operation efficiency and reliability.)

Q:Solar panels with single crystal silicon or good thanks
Strongly recommended products tested in the sun or cloudy days will not be worse than the single crystalPolycrystalline solar panels solar panels with batteries, our company is committed to the development of solar cell production, processing and sales as one of the most professional. Product solar panels: respectively, including epoxy encapsulated battery board (PET process components) monocrystalline silicon, polycrystalline silicon, as well as laminated toughened glass packaging large components and amorphous silicon solar panels
Q:How much can the domestic high - temperature solar collector reach
The tower system, Zhongxingpengyue pattern, looks very spectacular, is the image project of solar thermal power generation love. Its size is limited to 10~20 megawatt level, the use of special, very limited usefulness. The tower system operating temperature 600~1000 degrees Celsius, there are several foreign demonstration projects, the home also has heard, but I do not know the specific progress to that stage, both at home and abroad have not heard of commercial operation successfully.Dish type system, the operating temperature of 700~1400 degrees Celsius, stand-alone dozens of kilowatts, the system 5~25 mw. Due to the small machine, a large number of prototypes developed at home and abroad, but also did not hear of a successful large-scale commercial operation example. Due to the use of Stryn hot gas engine, its manufacturing technology requirements are high, greatly limiting its development.
Q:Solar products must be in the sun
Energy (Solar), generally refers to the sun's radiant energy, passive use (photothermal conversion)
Q:How about the effect of wall hanging solar energy
Cloudy conditions, it is estimated that it will not be too hot, no care. If there is light in winter, then normal heating, you can use
Q:Buy solar water heater mainly look at what?
Buy solar water heater mainly look at what?CDR | outside browse 976Recommended 2016-07-10 11:21:15 best answerBuy solar water heater, the four attention"First, the three components is the key to buy solar water heaters, analysis of production strength is very important. The strength of the enterprise is reflected in many places, and the key components are the most important. Three components include: vacuum tube, insulation layer and liner. The vacuum tube and the insulation layer determine the temperature rise and thermal insulation of the water heater, and the inner liner determines the life of the water heater, so these three parts are the core of the solar water heater. First, in accordance with national standards, the vacuum tube must be relatively high cost of high borosilicate 3.3 glass material, so as to ensure its light transmission and compression, anti-corrosion, impact resistance.
Q:What are the solar products?
Solar water lamp power supply, inverter solar watch packaging glass packaging film melted material monitoring system wiring box of solar wind cap regulator controller
Q:Solar electric vehicle charging device
Electric vehicle solar energy products are small in size, light in weight, easy to install and carry. Is a domestic initiative, has applied for national patent. Market potential is very large, very broad prospects.
Q:What about solar products?Solar panels solar panels
Solar modules on the equivalent of a battery, what the use of their own to think about
Q:30MW solar thermal power plant total investment
At present, there are three kinds of solar cells, such as monocrystalline silicon, polycrystalline silicon and amorphous silicon. Monocrystalline silicon solar cell conversion efficiency of up to 20%, but the price
Q:Is there any water in the solar energy to water?
How much is the automatic water supply set level up to the number 2 can not need to fill 100 set automatic water temperature time to remove any fill
