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 energy products, that is, I would like to open a home solar products Daquan
Photoelectric, two large blocks of light and heat, I think it will be a complete. But a lot of financial strength to do it
Q:Buy solar water heater mainly look at what?
Second, liner thickness. The quality of the liner determines the life of the water heater, if the water tank, the water heater will be scrapped. Major brand manufacturers use thickness of not less than 0.5mm of SUS304 food grade stainless steel liner. Argon arc welding is adopted to ensure the service life can reach more than 15 years. Other brands of water heaters in the liner between 0.2mm-0.4mm, the use of a period of time there will be water leakage problem. Therefore, consumers in the purchase of products must ask the thickness of the liner. At the same time, but also beware of patch water tank, the water tank liner is made up of a number of scrap steel belt, the entire inner bladder welding as many as dozens of times
Q:Now there is no sun, cloudy days can use solar products?
In addition, if you are a household, engage in electric heating can be complementary to each other!
Q:Is there any water in the solar energy to water?
Yes, but it's best not to add water during the day
Q:Product category and comparison of solar thermal utilization
Why choose a new type of efficient flat plate solar water heater (device) system?In recent years, the use of solar thermal products in China has been rapid development. In the solar water heater manufacturing, use and market share, China has far ahead. However, due to the use of solar thermal products in domestic vacuum tube based, in full swing in the development of the industry, but also exposed a lot of worrying problems.
Q:Solar panels can be charged directly to mobile phones and other products
Solar panels because of light effects, such as shadow, the angle, so the output voltage is not stable, not stable in 5V, generally with a simultaneous mobile power output and input to the panel itself has a built-in battery, then of course better.
Q:How much can the domestic high - temperature solar collector reach
Solar thermal power can be divided into three categoriesTrough system, tower system and dish system, they all belong to medium and high temperature system,Trough system is relatively popular in the other two categories, but also the most promising class. Operating temperature of 400~700 degrees Celsius, the scale is not limited to a few dozen megawatts, up to the level of Gigabit, there are some examples of successful commercial operation abroad. There are many prototypes in China, but there is no practical system.
Q:Good solar polymer or monocrystalline
Many of my friends would ask is good or good crystal crystal, we many people buy just as ordinary lighting and small system to watch TV, to tell the truth this is really no need to care about the single crystal or polycrystalline, regardless of the need is a power is enough, two is the price is good!The difference between polycrystalline and single crystal: single crystal plate is black, polycrystalline plate is blue or color.Disadvantages: the same power of the single crystal plate with polycrystalline plate, polycrystalline board area slightly larger than the area of single crystal board, the same as the 50W polycrystalline will be 1.1 times larger than the single crystalThe utility model has the advantages that the polycrystalline plate is a plurality of directions to receive light and has good directivity. The actual test, hypothesis with one hand to block the sun's rays to solar power on the surface of a shadow, so many crystal board power current decrease is not obvious, but the single plate power current is reduced obviously, this is the advantage of multi crystal plate.
Q:How to open solar stores
The store is fixed, the operator store is active, to store as a sales point, to regional radiation operations, will revitalize the store". Travel to a new solar 5S shop transaction according to the author, the store address provided by the dealer, the way to find the past, turned half an hour did not find a living map, taxi drivers are also puzzled, and finally had to ask the clerk to shop the way to reach the destination. The new store is completely in line with the provisions of the company, but what you want to find the store, even the best, are castles in the air for consumers, the effect not large, dealers pay no return. The development of the store, the author thinks that in order to repair the expansion, double attack. Let people pay attention to the store to enliven sales, real effort outside the shop. Although the products set up shop, but out of the store to sell, will make the distribution as boundless as the sea and sky. Target customers want to buy your product, how to let them find your shop? How to let more people know that you are selling some kind of solar energy products? Make use of all available opportunities, resources, and ways to hit your local brand! Let you fill the local market.
Q:What is the future of solar power
Those who despise misleading consumer advertising! Solar power generating capacity per square meter is about 120W, the cost per square meter 1500 yuan in the area, the greater the lower the price of 2013 the PV industry has been an antitrust investigation in Europe, because of overcapacity in Zhejiang's large solar photovoltaic industry collapse, the price fell down. This can always online inspection recommended the purchase price of solar water heaters each priced at 150-180 yuan according to material, and other costs, the purchase is optimistic about the local power and reliable customer service of solar panels, the size of the group suggested bidding, mainly electric power and storage equipment is very expensive, the highest conversion rate in 17%-20% efficiency is very low now, as the plant photosynthesis national clean energy, photovoltaic power generation policy is more than 10kW can free grid, but the recovery price is very low, cumbersome.
