The company is a leader in ultrahigh-voltage direct current and voltage source converter–high-voltage direct current (HVDC). With a grid spanning 2,000 kilometres, CSG is connected to hydro, coal, nuclear, gas, wind, solar, biomass, pumped storage and new energy storage power sources.

These batteries store the DC electricity generated by the solar panels, allowing users to access power during the night or on cloudy days when sunlight is scarce.
[pdf] Depending on your family’s energy use, you may need a system that generates more or less electrical power. Ensure that your system will generate enough electricity during the day and, if desired, enough.
