Grid inverter

The main function of the inverter is obviously to convert the DC power of the PV array into AC power compatible with the grid requirements.

The inverter model and the associated parameters are fully described in the chapter "Component Databases > Grid inverters".

Warning

Grid inverters should not be confused with inverters for standalone systems.

These are quite different devices, their features are:

  • The input power is the battery DC constant voltage, without current limitation.
  • Power output is determined by user needs, not available input power.
  • Therefore, it would be impossible to operate electrical loads according to solar availability (except for special applications like pumping systems, where water serves as storage).
  • Grid inverters cannot operate without the grid as an energy sink. They must stop producing electricity immediately if the grid disconnects or shuts down.
