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:Consumer behavior analysis of solar water heater
Consumer behavior analysisConsumers in the purchase of products, often have to consider the physiological needs, safety and health needs, psychological factors (environmental sustainability, energy saving, economic and other factors), at the time of purchase, often face 5 kinds of risk perception: one is the financial risk, that there may be a waste of money; the two is the function of risk, if function is not so good, or no brochures and advertising on the good; three is the physiological risk, looks a bit dangerous, afraid might get hurt; four is the social risk evaluation from fear surrounding friends not good; five is the psychological risk, because buy guilty, it would be irresponsible. For solar products, because the product and installation specification is not perfect, the implementation of the implementation of the lack of supervision, consumers lack of understanding of the core technology of solar energy, solar water heater does not have a clear understanding, in order to "Huiyanshizhu, consumers in the purchase, will be the main value of the brand, including corporate brand, product brand and service brand is the basis for the choice of consumers, because the brand is a commitment to consumers, its excellent quality, strong customer service service will guarantee the legitimate rights and interests of consumers; the value of quality products, to effectively meet the target market demand, such as the market part of the solar water heater can meet the demand of hot water in summer. But one winter has become idle goods, and even pipe cracking; value service, service satisfaction value, such as" Baidu service 100% satisfaction, service a little more satisfied with a little, through the service to reduce the risk of consumer awareness of the purchase.
Q:How to open solar stores
The solar industry is not mature, thousands of manufacturers, the winter "evaporation" summer prosperous seasonal manufacturers to consumers without security, therefore, with the help of the selected brand manufacturers force, forming and other brand segmentation is very important. In store layout, arranged according to the national unified you have chosen is specified by the manufacturer of the store template, establish the standard image of the store, which is beneficial to the consumers of your store "authentic" recognition, to "store security", according to the promotion plan provided by the manufacturer, with you in the local the promotional ideas store promotional site layout. Outside the store hanging promotional banners, the store posted eye-catching promotional posters, shopping guide to wear uniform clothing to consumers with a good visual image. Unified image of the terminal to do a good job, consumers will think that the product is reliable. Through training, so that the target customers to keep the root". Most of the customers entering the store is the target customers, to retain this part of the customer, to work hard on the training. In the terminal market, direct contact with the customer's shopping guide, shopping guide thrust plays a decisive role to a certain extent, in the solar energy marketing, customer and sales information is asymmetric, the customer can ask the seller about the solar energy many knowledge, if the sales sales ability is not strong enough, for the customer asked miss some of the main selling point, will sell in a passive state, natural products are unable to reach a deal, the good selling performance does not come out, it will be the loss of a large number of customers
Q:What are the forms of solar energy products
Solar hot water, solar photovoltaic power generation, various solar lamps
Q:Solar energy has some disadvantagesDetailed description of the problem, to help the respondents give accurate answers
Disadvantages of solar energy:The use of solar energy has its drawbacks:First, the current density is low, the sun is better, the ground floor area of 1 square meters of energy received only about 1 kilowatts. It is often necessary to set up a large number of lighting surface to meet the use requirements, so that the large area of equipment, materials, cost increases.Second, the greater the impact of the atmosphere, to bring a lot of difficulties.
Q:Home solar heating products can not mature?
Solar panel power generation, then the proposed size of the proposed group, mainly the power substation and storage of electrical equipment is very expensive, the highest conversion rate in the 17%-20% efficiency is very low, not as good as plant photosynthesisNow the national clean energy, photovoltaic power generation policy is more than 10kW can be free of charge, but the price of electricity recovery is very low, cumbersome procedures.Buy solar water heaters, the first proposal to consider the local climate, installation conditions, economic prices and durability
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:Solar products must be in the sun
Energy (Solar), generally refers to the sun's radiant energy, passive use (photothermal conversion)
Q:Solar garden lamp product parameters
Rainy days guarantee: can work continuously for more than 15 rainy days (regional / seasonal different) (can be made on request)Without the need for laying underground cables, without payment of lighting, key components of solar panels, solar garden lights the solar street lamp intelligent controller, DC maintenance free storage battery and a lighting lamp through the national development and Reform Commission, the world bank /GEF/ photovoltaic products certification. The utility model is mainly suitable for the lighting and lighting of the city road, the small square, the industrial park, the scenic spot, the park green belt, etc..
Q:Now there is no sun, cloudy days can use solar products?
The amount of radiation of solar water heater is the meaning of the sun. The sun did not reach that he cannot.
Q:New solar productsI want to know the new solar energy
Their idea is to paint more than two kinds of dye in a certain proportion, and paint it on a special glass window. These dyes can absorb different wavelengths of sunlight, and then through the glass window to concentrate sunlight on the edge of the window solar cells. Solar cells convert light energy into electrical energy.
