Photovoltaic inverter is an inverter that converts the variable DC voltage generated by photovoltaic solar panels into alternating current (AC) at the mains frequency. As one of the main components of photovoltaic power generation systems, photovoltaic inverters undertake important functions such as AC/DC conversion, power control, and off grid switching of the entire system, and are key to ensuring the long-term reliable operation of photovoltaic power plants.

Acid dew point refers to the condensation temperature of acid dew formed after combustion when the fuel has a high sulfur content. The higher the acid dew point, the more serious the corrosion of acid dew on the steam receiving surface. For combustion engineers, determining the acid dew point temperature of heating furnaces and boilers is the key to improving their thermal efficiency and reducing operational safety hazards. Therefore, the acid dew point meter has become an important tool in the combustion process of fuel-based energy. It plays an important role in equipment safety testing, environmental protection testing and combustion safety testing.

Power transformer is an electrical device that can change the magnitude of AC voltage and is an important component of the power system and power supply system. Through power transformers, current can be increased and decreased to meet different electricity needs. Due to the high transmission current, power transformers usually use a wiring nose at the end of the cable to connect to the PCB board, ensuring a strong connection between the cable and the PCB board to prevent accidents from occurring.

Energy PCBA is a PCBA circuit board applied to energy management equipment, which can remotely and predictively manage and maintain energy equipment, effectively reducing maintenance costs and downtime of energy equipment, and ensuring power generation safety. Due to the special working environment of the energy industry, the reliability requirements for PCBA circuit boards are more stringent.

Energy storage battery refers to the energy storage battery used in solar power generation equipment, wind power generation equipment and other renewable energy sources. It consists of an energy storage battery, a master controller unit (BAMS), a single battery management unit (BMU), and a battery pack-side control and management unit (BCMU). BMS is the management system of the energy storage battery, which is responsible for monitoring the running status of each battery in the battery energy storage unit at all times, and realizes complete communication, monitoring, management, control, early warning and protection functions.

The battery module test system is a kind of equipment specially used to test the charging and discharging performance of various power batteries (lead-acid, nickel hydride, lithium battery, supercapacitor, Hydrogen fuel battery, etc.). With the increasingly widespread application of power batteries, the market has put forward higher requirements for the portability of battery module testing equipment.

Intelligent power instrument is a widely used intelligent power monitoring instrument in distribution systems, which integrates many functions such as telemetry, remote signaling, display, output, communication, etc. The equipment has the characteristics of high precision and reliability, and is widely used in medium and low voltage transformation and distribution automation systems, industrial automation systems, intelligent switchgear, building automation systems, load control systems, energy management systems, and factory power assessment management.
