Countries like the UK have implemented standards such as G98 and G99, which regulate small- and large-scale generator connections to the grid, prioritising safety, grid stability, and efficiency.
This investigative article exposes the discovery of undocumented communication devices hidden in Chinese-made solar inverters, creating unprecedented vulnerabilities in global power grids.
Summary: This guide explores the critical steps and best practices for photovoltaic inverter installation and grid connection, tailored for solar energy professionals and homeowners. PDF version includes complete article with source references.
Before connecting the inverter to the grid, ensure the grid voltage and frequency comply with inverter(s) technnical specification. Otherwise, contact the electric power company for help.

This part of IEC 62909 specifies general aspects of bi-directional grid-connected power converters (GCPC), consisting of a grid-side inverter with two or more types of DC-port interfaces on the application side with system voltages not exceeding 1 000 V AC or 1 500 V DC.
The industry standard suggests that the inverter's capacity should be between 80% to 125% of the solar panels' capacity. For example, if your panels generate 10 kW: Minimum inverter size = 10,000 x 0. 5 kW.
