How do inverters provide grid services?
In order to provide grid services, inverters need to have sources of power that they can control. This could be either generation, such as a solar panel that is currently producing electricity, or storage, like a battery system that can be used to provide power that was previously stored.
Can an inverter be placed anywhere on a solar PV system?
Therefore an inverter output to 50A (125% of rated output current) can be placed anywhere on the bus because the sum of both sources would be 200A. Since the bus is rated for 200A, there is no potential for overload. Downsizing the main can be used in combination with the 120% rule to connect larger solar PV systems.
Why do utility companies build digital walls around inverters?
They're also embedded in home batteries, electric vehicle chargers, and even heat pumps. Because they often require remote updates and maintenance, inverters are designed to be connected to the web. But to prevent tampering or intrusion, utility companies typically build digital walls around them.
