2.1 Intended Use
The Sunny Boy is a PV inverter which converts the DC current of the PV array to AC current and feeds
it into the power distribution grid. The Sunny Boy is suitable for use with fuel cells, small wind turbine
systems, and other DC current sources. You can use the AC electricity generated as follows:
Household grid:
Power distribution grid: Energy is fed directly into the power distribution grid. The Sunny Boy is
Stand-alone grid:
Interconnection Code Compliance
The Sunny Boy has been checked by the certification body and certified according to the guidelines
in UL 1741 Static Inverters and Charge Controllers for use in Photovoltaic Power Systems, IEEE 929-
2000 Recommended Practice for Utility Interface of Photovoltaic Systems, and IEEE 1547 Standard
for Interconnecting Distributed Resources with Electric Power Systems.
UL 1741 is the standard used for the Sunny Boy by the certification body in order to
certify that it complies with the regulations of the National Electrical Code
IEEE 929-2000. IEEE 929-2000 states recommendations regarding the appropriate
equipment and functionality that is required to guarantee fault-free operation when the
power generation is connected to the power distribution grid.
The Sunny Boy is also certified in accordance with Canadian Electrical Code
C22.2 N0. 107.1-01 (General Use Power Supplies).
Prior to designing and installing your PV plant, contact the local grid operator or the
responsible authority.

Energy flows into the household grid. The loads connected, for example
household devices or lighting, consume the energy. The energy left over is
fed into the power distribution grid. When the Sunny Boy is not generating
any energy, e.g. at night, the loads that are connected are supplied by the
power distribution grid.
The Sunny Boy does not have its own energy meter. When energy is being
fed into the power distribution grid, the energy meter runs in reverse.
connected to a separate energy meter. Depending on the electric utility
company, you will be remunerated accordingly for the energy generated.
The Sunny Boy is connected to a stand-alone grid. A stand-alone grid is a
grid that is not connected to a power distribution grid. The Sunny Boy needs
a grid-forming generator, for example, a Sunny Island, in order to function.
The energy generated is consumed directly on site, surplus energy can be
stored in batteries.
