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:

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

and

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

CSA

C22.2 N0. 107.1-01 (General Use Power Supplies).

Household grid: 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.

Power distribution grid: Energy is fed directly into the power distribution grid. The Sunny Boy is

connected to a separate energy meter. Depending on the electric utility

company, you will be remunerated accordingly for the energy generated.

Stand-alone grid: 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.

Prior to designing and installing your PV plant, contact the local grid operator or the

responsible authority.
