At present, there are many models of inverters on the market. In order to simplify management and explore the advantages of centralized procurement, many EPC manufacturers often use limited inverter models to do as many field designs as possible, which will inevitably involve the reduction of inverters. Content usage issues. A small reduction in capacity is not a big problem; but a large reduction...
Photovoltaic inverters are composed of circuit boards, fuses, power switch tubes, inductors, relays, capacitors, displays, fans, radiators, structural parts and other components. The service life of each component is different. The service life of the inverter can be explained by the "barrel theory". The maximum capacity of the barrel is determined by the shortest board, and the service life of th...
Inverters running in summer may feel hot to the touch due to their high shell temperature. And why does the casing feel hot? The following will do some analysis and answers for these two problems combined with inverter heat dissipation. The components in the inverter have their rated operating temperature. If the heat dissipation performance of the inverter is poor, as the inverter continues to wo...
Reasons for low insulation resistance: When the solar panels or DC cables and joints are damaged or the insulation layer is aging, the problem of low insulation resistance is easy to occur. When the DC cable passes through the bridge, since the edge of the metal bridge may have barbs, the outer insulation of the cable may be damaged during the threading process, resulting in leakage to the ground....
In recent years, with the continuous reduction of the cost of photovoltaic power generation, photovoltaic power generation has gradually become the main energy source in the new power system. Module products are the core power generation equipment of photovoltaic power stations, and their safety and reliability will directly affect the power station long-term stable operation. Ensuring the quality...
On the evening of July 11, Deye shares issued an announcement saying that recently, the company found that the micro-inverters produced and sold by the company reported by the media were inconsistent with the certification. The article mainly questioned the micro-inverters sold by the company to Germany because of The lack of relays does not meet the German VDE4105 grid-connected certification con...
1、What’s the difference of Hybrid ACDC and normal air conditioner? Hybrid ACDC does not need inverter or battery, it works with unstable solar panel DC power at day time. At night or rainy days it automatically gets AC power. It is mainly used for school classroom, hospital, restaurant, shops, office… Normal air conditioner works with AC power. When AC power is not available, or with too big fluct...
With the popularization and application of industrial and commercial photovoltaics, more and more industrial enterprises are using their factory roofs to build photovoltaic power generation system. There is usually no objection to installing photovoltaics on the south slope, but how to deal with the installation of photovoltaics on the north slope of the color steel roof. Whether to continue to us...
Solar air conditioning system is any air conditioning powered by the sun's energy. Solar air conditioners have no emissions and supply their own energy, so customers can lessen their carbon footprint and reduce their energy costs at the same time. Types of Solar Air Conditioning The simplest form of solar air conditioning is a small solar panel that generates enough electricity to run a fan—for ex...
The ability of a solar power system to meet the electricity demand of monitoring devices depends on several factors, including the power requirements of the devices and the capacity of the solar system. When determining if a solar system can meet the electricity needs of monitoring devices, consider the following: Power Consumption of Monitoring Devices: Review the power specifications of the moni...
The grid-connected energy storage system refers to the power generation and energy storage system that is integrated into the grid, and the generated electricity may be used for its own use, and the surplus is supplied to other users in the grid. The entire system is a power generation system including photovoltaic module arrays, photovoltaic controllers, battery packs, battery management systems ...
