This series inverter for double transformation power supply system.When the power grid appear outage, voltage instability, voltage interference, surge, peak and mains noise and other bad phenomenon, can guarantee the load working normally.
Widely used in electric power, communication, radio and television, banking, taxation and IT industry etc. To provide quality stable power for equipment load.
1. normal operation
Battery through the isolation diode to inverter power supply, and then by inverter transformation into stable alternating current (ac), Through static switch switch to EMI output filter for filtering, Finally on the output side also get a pure stable power supply to the load. From the inverter fault to the mains supply the entire process output no intermittent time. At the same time, the mains through another branch supply to charger after transformation to the battery charging. Showen as below:
2. Automatic bypass operation
When in the following situations inverter will automatically switch to bypass state power supply:
1)The front panel "ON/OFF" button switch without press the trigger boot, or after trigger not go by 20 seconds testing time delay.
2) Standby state
3) Inverter output overload or battery low voltage
4) inverter circuit built-in malfunction
When there is above circumstance, after the input mains through the filter, is no longer through the inverter switching, but directly to the static switch, after switch to the filter and then filter output. In the bypass state, mains also can charge for the battery.

- Q:How to promote the use of solar energy in China
- In this regard, the government should do a lot of work, industry associations have also made the relevant advance
- Q:How to open solar stores
- There is a solar dealer, in the local solar market, can be described as a coup. Use the bus as a propaganda tool, bus station, the first sentence is: "a certain store solar power station to remind you:" in the caption on the bus, he hit the store's telephone and communication; on the phone 114, the opening of the new building signs, banners, and even background cloth Online shopping, playing a certain solar energy store. In view of the store is more than the target customers, the dealer also sent a trick to go back and forth to its store expenses reimbursement, in this way, the customer into the store. With the help of external forces, a good manufacturer of this card. Dealers in the choice to join an industry, have to go through thousands of pick million, so that the industry has the impact of brand agents.
- Q:What are the references of the solar automatic tracking system
- Tracking models were taken; gives the specific design ideas and methods of photoelectric tracking mode; to analyze and determine the sun trajectory calculation method, verified the feasibility of this method. According to the proposed tracking method, design a set of automatic tracking type independent solar photovoltaic power generation system. The system is a small photovoltaic power generation system based on automatic solar tracking, all-weather, high efficiency run independently, as much as possible the conversion of solar energy into electricity, to provide electricity load. The whole system is divided into automatic tracking system and two subsystems of solar photovoltaic power system, the photovoltaic power system is in the forest fire specific applications are analyzed and designed respectively. The design of hardware and software of the two subsystems. The hardware design includes the position of the sun and light intensity detection, calculation The software part of the system is designed, which is composed of computer control, data acquisition, external clock and photovoltaic power supply
- Q:How much does it cost to install solar energy in rural areas
- Four look at the brand, service. The solar water heater host outdoors year-round by professionals need to withstand exposed to wind and rain, maintenance, maintenance. At present, there are 4000 domestic solar water heater factory, as the country has not yet unified solar water heater testing standards, some of the quality of the product does not pass, installation services are not in place, to bring trouble to users. Buy solar energy is not only a product, but more importantly, service". Therefore, we should choose the strength of the brand name of professional manufacturers of products, such manufacturers to install service personnel are generally through professional and technical training, service and thoughtful, so that you do not worry, get the best protection.
- Q:What is the future of solar power
- The roof of photovoltaic power generation is less than 2 million monthly sales tax, in accordance with the provisions of the national taxation policy, power users need to provide sales invoices to the power supply enterprise, the buyer also need invoice offset the cost, and the personal power does not have the qualification of business owners, led by invoices complicated procedures. More than 20 thousand of the tax can not get the invoice, it increases the difficulty of the sales of power generation households, is not conducive to promotion. The State Administration of Taxation issued, will reduce the tax burden on household electricity." According to the State Administration of taxation documents, since July 1, 2014, the national Power Grid Corp to buy power products distributed photovoltaic power generation project, by the national Power Grid Corp invoices, monthly household electricity generating sales of more than 20 thousand products, owned by the national grid enterprises in accordance with the taxable amount of the 50% generation of vat. The monthly sales of less than 20 thousand yuan may be exempt from vat. According to the State Administration of taxation policy released last year, from October 1, 2013 to December 2015 3l, according to the 3% levy rate calculation. In Takamatsu as an example, if a month sales of 30 thousand, that he should pay the tax is 30 thousand x 3% x 50%=450 yuan.
- 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:Solar products must be in the sun
- Energy (Solar), generally refers to the sun's radiant energy, passive use (photothermal conversion)
- Q:What is the difference between the expensive solar energy and the cheap one?
- Cohesive light film vacuum tube is used their thermal power generation technology, positive negative light, heat, warming faster, higher water temperature, which is unique in the world (Himin patent, ultra cold polar tube, Antarctic expedition team designated products, 40 degrees below zero still out of hot water, hot water is not broken; they are equipped with low winter) the temperature of the water level sensor, accurate induction, automatic operation of the whole system, you don't have to worry about is not water ah, can bathe ah; not only that, once the hot water machine what, their customer service staff will serve you within 48 hours. This is not high price but not expensive, is the value for money, or even value for money?
- 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:New solar productsI want to know the new solar energy
- As a result, the room window has become a new type of "solar window", "guide" the sun gathered on the four sides of the solar cell. The previous solar cell concentrator, is the use of large areas of moving mirror to track the sun. It is only in the roof and other open areas to set up the previous condenser. In contrast, solar windows do not take up space, easier installation and low cost.
