What is an inverter?

A smart inverter will therefore ensure that you are able to use as much as possible of the solar power that your system generates yourself. Backup power supply: solar power can only be generated, used and, in combination with a battery, stored – even in the event of a blackout – if your inverter features backup power functionality.
