SMA  Sunny Boy Grid Tied Inverters

The Sunny Boy is a DC to AC grid-tied utility interactive inverter for use with photovoltaic (solar electric ), fuel cell, wind turbine and other sources of DC power.

 The Sunny Boy converts solar power from a DC source (solar panels) and converts it to AC power for the utility grid. This power is delivered first to local loads (appliances, lights, motor loads, etc.), with any excess power fed to the utility. The power consumed by the local loads reduces the power needed from the utility. Excess power may actually “spin the utility meter backwards” depending on the type of meter in your system. This power may also be recorded as power credits by the utility company depending on the interconnection agreement. An example of basic system components is shown in Figure below.

 Anti-Islanding Protection

Islanding is a condition that can occur if the utility grid is disconnected while the Sunny Boy is operating and the remaining load is resonant at 60 Hz (US based systems) and matches the output of the Sunny Boy perfectly. This condition is highly unlikely and had never been witnessed outside of a controlled laboratory. Nevertheless, the Sunny Boy utilizes an advanced active islanding protection algorithm to ensure that the system will not export power into a balanced 60 Hz resonant load while the utility is disconnected. The Sunny Boy periodically injects both leading and lagging reactive current into the utility grid. This method has been proven by Underwriters Laboratories to effectively destabilize and disconnect from a balanced island condition.

 

PV Ground Fault Detection and Interruption

The Sunny Boy is equipped with a ground fault detection device. If a ground fault current greater than 1 Amp is detected, the Sunny Boy will shut down and display the fault condition on the user interface display. Once the ground fault is located and corrected, the ground fault error will need to be manually cleared and the inverter will then resume normal operation
