Advantages of solar hybrid inverters

Hybrid solar inverter mainly has the function of solar on and off grid power generation, that is to say, in the case of normal power supply, the device closes the bypass relay to realize the power supply load on the household electrical appliance; When the power supply of the power network is not normal (such as the power grid is off, the power grid voltage or frequency fluctuation is relatively large), the device can carry out the power supply for the household electrical appliance after inverting through the battery. Under the condition of suitable sunshine intensity, the device can also be connected to the grid and sold to the grid to gain benefit when the solar power generation function is normal.
In terms of technical implementation, the device consists of the following units:
First is the inverter unit, the unit receive from solar power from solar panels and DC bus box, through the maximum power point tracking circuit, stable DC bus voltage, finally into the public power grid power generation by the inverter unit.
Second is the off grid solar inverter unit, when power supply is normal, through the bypass relay to the load power supply, at the same time to charge the batteries; when the power grid is out of order, through the inverter load to achieve uninterrupted power supply. At this time, if the PV module generates electricity, can be supplied to the load through the solar power inverter, and the battery is charged simultaneously.
Third is a switching unit, when the unit is in suitable light condition and the power grid is abnormal, supply power to the load through switching relays and other devices.
Fourth is the other auxiliary units, such as isolation unit, storage battery management unit, etc., used to achieve the management of storage battery, into the network, meters, network meters, solar panels and so on.
In general, the solar hybrid inverter can effectively overcome the existing problem of solar inverter is only suitable for grid connected generation, and when off grid inverter in the weak sun light, the electricity load is limit, can effectively improve the utilization efficiency of solar energy, especially suitable for power grid power supply is not stable or high cost.

Correct selection of backup time for UPS

图片
UPS backup time is generally a problem concerned by customer in the purchase process. Usually most people prefer to choose the  UPS  which power backup the longer the better, in fact, this is not correct. We must firstly clear that the seller will usually have standard type UPS and long-acting UPS. Standard type UPS with built-in battery, after a power interruption can supply power to the load equipment in general for a few minutes to tens of minutes, of course, the length of time depends on the load. Long acting UPS can not only meet the power requirement of load, but also meet the requirements of customers and work types and so on, so the long-term UPS is usually equipped with an external battery pack. If the client is not particularly strict to the work condition of the load, and the power of the load is not particularly large, usually with standard type UPS would be enough. Because the choice of long backup time UPS is bound to increase the number of battery groups an...

126th Canton Fair

图片
On Oct 15th 2019, as one of the most important trade promotion platforms for Chinese enterprises to expand the global market, Canton Fair in Guangzhou focused on highlighting innovation driven, and “independent brand” became a high-frequency word of Canton Fair. Xu Bing, a spokesman for the Canton Fair and deputy director of the China Foreign Trade Center, said that the domestic and foreign environment faced by China’s foreign trade development this year is more complex and uncertain. The majority of exhibitors accelerated quality improvement and innovation, and continued to make efforts in technology research and development, product innovation, brand cultivation, etc., with high technology, high quality, high added value and independent brand products emerging. Many independent innovative R & D products are welcomed by the market. At the same time, purchasers are less sensitive to price and pay more attention to the technology, brand, quality and service of products. In ...

How to maximize the efficiency of your UPS

图片
1.Use of AC voltage regulator After using  UPS power supply , there is no need to add AC voltage regulator. If it must be added, it should be added to the front level of UPS, that is, the mains power first passes through the AC voltage regulator, then through the ups, and then to the load. 2.Battery balanced charging skills At present, valve regulated lead-acid battery (VRLA) used in many ups power supply is called maintenance free battery from the beginning, which gives users a misunderstanding that it seems that this battery is durable and does not need maintenance at all. Under this kind of misleading, many users have not carried out maintenance and management since they installed the battery. When the battery in UPS power supply meets the following conditions, the battery shall be charged evenly: when the terminal voltage is lower than the specified calibration voltage due to excessive discharge. For 12 V small sealed lead-acid batteries, the discharge calibration voltage is...
