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.

Stick to contract.
- Q:Is there any water in the solar energy to water?
- Yes, but it's best not to add water during the day
- Q:PV solar products market sales
- The state has introduced the relevant subsidy policy, fairly good prospects.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.
- Q:What is the difference between photovoltaic products and solar energy?
- At the same time, the solar photovoltaic power generation system, which is centralized, such as large northwest ground photovoltaic power system; one is distributed (divided by >6MW), such as building roof photovoltaic power generation system of industrial and commercial enterprises, residential roof photovoltaic power generation system.Solar photovoltaic effect, referred to as photovoltaic (PV), also known as the photovoltaic effect (Photovoltaic), refers to the uneven illumination of semiconductor or semiconductor and metal parts of the potential difference between the phenomenon of.Photovoltaic is defined as the direct conversion of ray energy. In the practical application, it usually refers to the conversion of solar energy to electric energy. Its implementation is mainly through the use of silicon and other semiconductor materials made of solar panels, the use of light to generate direct current, such as our daily lives can be seen everywhere in the solar cell.
- Q:What are the third generation solar cells
- What criteria are you referring to?There is not a recognized way of generational change;So there is no way to answer!
- Q:What are the forms of solar energy products
- Solar hot water, solar photovoltaic power generation, various solar lamps
- Q:Are solar panels now in use?
- Servo drive, also known as "servo controller" and "servo amplifier", is used to control the servo motor
- 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: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 disadvantages of traditional solar water heater
- We now have a factory in Wuxi, the production of solar water heaters, the core components - superconducting heat pipe, so that the product in place. Heat pipe is a vacuum glass tube inside, no leakage, no water absorption of solar heat, but the use of dark metal materials such as heat transfer, heat transfer efficiency is high temperature superconducting material.
- Q:How much does it cost to install solar energy in rural areas
- Two see insulation performance. The storage tank is a hot water storage tank, and its performance is mainly reflected in the insulation effect. Good insulation not only depends on the thickness of the insulation layer, but also insulation materials and processes. The use of automatic numerical control constant temperature and constant pressure quantitative foam, high temperature curing, thickening insulation layer of the water storage tank to ensure that the layer is more compact symmetry, thermal insulation performance is more durable.Three see bearing strength. Like the solar stent skeleton, of course not fragile. At present, there is a more streamlined tower support, which uses reinforced, super high base, to overcome the traditional thin rod bracket thin wind resistance of the problem, wind, rain, hail, corrosion resistance.
