What does MPPT technology mean in photovoltaic power generation

The full name of the MPPT solar charge controller is Maximum Power Point Tracking solar controller, is the upgrade products of traditional solar charging and discharging controller. The MPPT controller can detect the generation voltage of the solar panel in real time and track the maximum voltage current value (VI), so that the system can charge the battery with maximum power output. Applied to the solar power system, coordinate the work of solar panels, batteries, and loads, is the brain of solar systems.
The maximum power point tracking system is an electrical system that allows photovoltaic panels to output more power by adjusting the working state of the electrical modules. It can store the direct current generated by the solar panel effectively in the storage battery, which can effectively solve the life and industrial use of electricity in remote areas and tourist areas not covered by the conventional grid, and no environmental pollution.

What is the function of MPPT?

Because of the solar cells influenced by the intensity of the received light and environment and external factors, the output power is changed, the solar power inverter with MPPT is to make full use of solar cells, keep it at the maximum power point, which is the function of MPPT.
PV array is connected with a load through the DC/DC circuit, MPPT device to detect the change of the current and voltage of photovoltaic array, and according to the change of the DC/DC converter PWM drive signal duty cycle adjustment.
For linear circuits, when the load resistance is equal to the internal resistance of the power supply, the power supply has the maximum power output. Although photovoltaic cells and DC/DC conversion circuits are strongly nonlinear, they can be considered as linear circuits in very short periods of time. Therefore, as long as the equivalent resistance of the DC-DC conversion circuit is adjusted, so that it is always equal to the internal resistance of the photovoltaic cell, the maximum output of the photovoltaic cell can be achieved, so the MPPT of the photovoltaic cell is realized.

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...
