Abstract
A photovoltaic inverter system and a method, and a PID effect compensation device for the photovoltaic inverter system are provided. A processing control unit records operation conditions of photovoltaic modules, determines whether a PID effect compensation condition is met, calculates a compensation voltage optimally and controls the integrated PID compensation device to perform PID effect compensation on the photovoltaic modules.
