At night, when a solar inverter is not actively generating real power (PV output is zero), it can still provide reactive power support to the grid by operating in Static VAR Generator (SVG) mode. However, because the output power of PV systems will be affected by factors such as weather and temperature, resulting in changes in the active power output to the grid connection point, the reactive power adjustment of the system is required to stabiliz. . In this article, we will explain the concept of SVG and how SolaX C&I on-grid inverters can be utilized with integrated SVG functionality, leading to improved power quality and enhanced grid stability. Static Var Generator (SVG) is a power electronics-based device that provides dynamic reactive. . SVG detects the phase angle difference and generates leading or lagging current into the grid, making the phase angle of current almost the same as that of voltage on the transformer side, which means fundamental power factor is unit.
