Inverters are also called power regulators. The process of converting DC power into AC power is called invert. The circuit that can realize the inverting function is called an inverter circuit. A device that can realize the inverting process is called an inverting device or inverter. In a solar energy generation system, the inverter efficiency is an important factor that determines the solar cell capacity and the storage battery capacity. The breakdown of PV inverter will cause the PV system to shut down and this directly leads to the loss of power generation. Therefore, high reliability is an important technical indicator for PV inverters.
The good cooling of PV inverters is an important criterion to ensure the high reliability of its operation. Therefore, it is recommended to carry out thermal simulation in the beginning of PV inverter's design stage and this has become the first issue to be considered by PV inverter manufacturers. As one of the professional high power cooling manufacturers in China, Winshare Thermal has an outstanding thermal design and development team, which owns the capability of carrying out reliable thermal simulation and testing. We have collaborated with several domestic and overseas PV inverter manufacturers on the cooling technology for inverters and have been supplying services and supports with our professional cooling technology.
