What is a PV Inverter; A inverter is an electrical device that converts direct current (DC) into alternating current (AC). It consists of an inverter bridge, control logic, and filtering circuit. Specifically, it converts low voltage (12 V, 24 V, 48 V) into high-frequency AC power supply (220 V). the most commonly used is PWM

The testing items for power transformers and reactors are as follows: (1) Chromatographic analysis of dissolved gases in oil; (2) The DC resistance of the winding and the bushing (to determine the welding quality of the coil internal joints, lead to coil joints, tap changer to lead, and whether there are open circuits and short

In this post, we only talk about distributed PV power plant. Following issues, we need to consider when we connect a distributed PV plant to local grid network. Grid voltage adjustment: According to the requirements of the power grid company, adjust the grid voltage of the distributed photovoltaic power station to ensure its matching with
