The solar hybrid AC/DC air conditioner can work without battery, it works with unstable solar panel DC power at day time. At night or rainy days it automatically get grid AC power. It's mainly used for school classroom, hospital, restaurant, shops, office… With APP monitor and control function through WIFI
View MoreThe MPPT solar charge controller uses multiphase synchronous rectification technology and common negative pole design, it chooses high speed processor and advanced MPPT algorithm to make it has high response speed, high reliability and other standards. The advanced MPPT algorithm that the solar controller adopts can trace the maximum power point of PV arrays quickly in any situation to obtain the max. power from PV arrays. And the multiphase synchronous rectification technology can achieve high conversion efficiency in any charging environment and improve the utilization rate of solar power system greatly. According to the rated voltage of battery bank system, our factory can provide the MPPT solar charge controller from 192V to 540V which suitable to almost off grid solar power system
View MoreAn on-grid inverter’s main job is to convert DC power generated from the PV array into usable AC power. Hybrid inverters go a step further and work with batteries to store excess power as well. In the developing world, hybrid inverters are more of a necessity to compensate for weak or intermittent grids or a lack of grid electricity all together.

What is the energy storage inverter? This question is relative to many friends want to understand it, because the inverter we all know that the inverter is mainly a DC to AC transformer, it is actually with the converter is a kind of voltage inversion process, then the storage inverter and how is it? Next let the professional Gu Rui Watt storage inverter manufacturers of the editor to give you a detailed explanation of what is the storage inverter it. Energy storage inverter can be said to be the latest generation of inverters on the market today, energy storage, as the name implies, is the conversion of alternating current (AC) into direct current (DC) power stored in the battery, when a power failure occurs, the storage inverter will be converted to AC power in the battery for the user to use the DC power to provide users with the grid power and the two-way conversion of the battery between the electrical energy to break through the limitations of the photovoltaic inverter can only be used during the daytime, which is why storage inverter can be used for the user's energy storage. Limitations, which is why the storage inverter itself is more and more popular with the user's important reasons. The main functions and roles of energy storage inverters are introduced. The main function and role of the energy storage inverter is to realise the bidirectional energy transfer between AC grid power and storage battery power, and it is also a kind of bidirectional converter, which can be adapted to a variety of DC energy storage units, such as supercapacitor bank, battery bank, flywheel battery, etc., which can not only quickly and effectively achieve the suppression of distributed power generation systems to achieve the fluctuation of the random power or current, but also increase the power grid's capacity for large-scale renewable energy power ( wind power, photovoltaic), which is the main reason why it is becoming more and more popular among the users. Wind energy, photovoltaic) acceptance capacity, and can accept scheduling instructions, absorb or supplement the peak and valley power of the grid, and provide reactive power, in order to improve the quality of power supply and economic efficiency of the grid. In case of grid failure or blackout, it also has the function of independent network power supply to improve the security of power supply to the load.
Solar photovoltaic power generation is an important part of new energy and renewable energy. Because it integrates the development and utilization of green renewable energy, improves the ecological environment, and improves people's living conditions, it is considered to be the most promising new energy technology in the world today. , so it is becoming more and more popular among people. There are usually two ways to utilize solar power generation. One is to transmit the power generated by the solar power generation system to the power grid for use by other loads, and when power is needed, power is obtained from the power grid, which is called grid-connected power generation. The other is the so-called independent power generation method that relies on batteries for energy storage. It is mainly used in situations where mains power cannot be reached due to difficulty in setting up lines, and is widely used. The 5KW solar off-grid power generation system is an independent power supply system. The system consists of photovoltaic modules, photovoltaic DC cables, photovoltaic brackets, charge controllers, lead-acid batteries, inverters, etc.
