2.1 Appropriate Usage

The Smart Load is an electronic load for stand-alone grid systems equipped with Sunny Island. It
identifies the grid frequency and determines whether an energy excess is present. The Smart Load
converts the excess energy into heat using an external resistor or heating cartridge. You can also
externally specify the nominal value of the power to be output.
Principle of a stand-alone grid system equipped with Smart Load
Sunny
Island
The Smart Load has a nominal power of 6 kW. The single or three-phase AC input voltage is 230 V
or 3 x 230 V. One load resistor with a power consumption of 6 kW or 3 load resistors with a power
consumption of 2 kW can be connected to the DC side of the Smart Load. The DC voltage is 230 V.
The Smart Load is suitable for Sunny Island stand-alone grid systems whose nominal voltage is
230 V or 3 x 230 V. The frequency can be 50 Hz or 60 Hz. Observe the limits specified by the
manufacturer.
The Smart Load is only suitable for original SMA accessories or accessories recommended by
SMA.
Appropriate usage also includes observing all the documentation.
