Product Description:

Product overview:

The inverter 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.
 20KW Single-Phase 220VAC Power-Frequency Solar Power InverterMain 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:What are the current domestic solar energy products, which practical
Our use of solar energy can be roughly divided into two types of light and heat conversion and photoelectric conversion, in terms of household solar water heater and solar photovoltaic power generation.The solar water heater is widely used, manufacturers have Wuxi Suntech, linuoruite, Himin Solar energy, I think the emperor of the more, certainly not bad.
Q:Solar products must be in the sun
Other light sources can be used to meet the needs of the product (e.g., solar watches can be recharged by other light sources)
Q:What are the functions of the new vehicle negative ion solar charging humidifier?
Brown vehicle negative ion solar charging humidifier, in addition to negative ions and solar charging function, but also can be used as car fragrance, you can add essential oils.
Q:Household solar energy productsThe product can be used at home, do not mention the solar energy, answer the water heater
Divided into two large photovoltaic and thermal.Photovoltaic power plant used in the battery board has two kinds of polysilicon and monocrystalline silicon, which is a little higher conversion rate. A solar photovoltaic system of solar power generation system, glass curtain wall, large on / off grid systems (e.g. Tibet Yangbajing engineering). In addition, there are solar street lights, scenery complementary street lights, solar lights, solar LED screen, solar backpack, etc.
Q:Buy solar water heater mainly look at what?
Two, after-sales service is very important in accordance with the three products, the principle of service of seven points. After sales service in the choice of solar water heater also plays a big role. With the development of solar energy industry, more and more manufacturers, in these new manufacturers, many do not have plant equipment, parts to take OEM processing, business variables, quality is difficult to guarantee. Due to the small sales, when operating for a period of time after a loss and product quality problems, will run away. The products are sold without service. So in the choice of solar water heaters, the choice of large brand products is essential.
Q:What are the solar products?
Solar water heater solar range solar heatingSolar energy air conditioning hot water system solar panel solar energy power generation system encapsulation glue film solar battery lawn lamp garden lamp scenery complementary lamp signal lamp landscape lamp buried lamp
Q:Solar heating easy to use? Has anyone used it
If your house has a little heat preservation effect, the heat collector area is not enough. The first is fraud, very high! Followed by the heat collector is often no place to swing! Again, so many collectors, the heat generated in the summer there is also a problem
Q:How to choose a good use of solar energy
See building structureMulti story building: installation is not limited, vacuum tube solar energy and flat panel solar energy products can be selected. Senior and small high-level: balcony solar energy products can choose. Villa Construction: can choose to install flexible, can be integrated with the construction of flat panel solar energy, flat panel solar energy is not affected by high-rise and special buildings, beautiful and generous.See pipeBecause the water heater is often placed on the roof, there is a certain pressure and the house in the summer, hot water with high temperature (about 90 DEG C), the actual situation of low ambient temperature, so the best selection of crosslinking tube or plastic composite pipe or reinforced plastic hose. The utility model has the advantages of high pressure resistance, high temperature resistance, low temperature resistance, no toxicity, no odor, small heat capacity, small heat loss, and easy to freeze in winter.After-sale serviceThe best choice of well-known brands and the strength of dealers (longer distribution time, product quality complaints rate) of the water heater. Because the solar water heater is durable consumer goods, and usually installed in the roof, once the fault, it is difficult to deal with their own. So the customer service service must be guaranteed, at present, the whole market free warranty period of 3 - 5 years.
Q:Solar electric vehicle charging device
Performance characteristics of solar charger for electric vehicle:1 suitable for 36V, 48V configuration of the electric vehicle voltage conversion2 unique electric vehicle battery repair function, because of its continuous battery to supply electric power to prevent and remove the battery plate sulfide, recovery of battery capacity, prolong battery life, reduce the economic burden of the users.3 using the level of intelligent tracking system, the use of a new track concept, to achieve a day in the system of the sun's automatic tracking, improve the photoelectric conversion rate, increase the power supply to the battery.4 unique overvoltage protection technology to ensure the safety of charging equipment.
Q:How to develop solar photovoltaic industry
The world climate change, because solar energy is a one-time investment, the current data show that solar power business life cycle for 25 years, before 3 - 5 years for solar power plant manufacturing cost, the carbon dioxide produced far less than the size of the fossil power plant, therefore, the climate change and carbon dioxide emissions contribute to global; 4, the application prospect of solar energy is very extensive, both the roof power station, large-scale solar power plants, or used in human life will be very popular, the power system involves the possible and the sun can be combined.
