Intended Use

Sunny Boy 240

The Sunny Boy is a micro inverter for PV systems that converts the direct current from a PV module into grid-compliant alternating current. The alternating current generated is fed into the utility grid via the Sunny Multigate.

The product is suitable for indoor and outdoor use.

The Sunny Boy must only be connected to one PV module. The PV module used must comply with protection class II as per IEC 61730, application class A and must be compatible for use with the Sunny Boy. The Sunny Boy must be operated with the Sunny Multigate.

  • Do not connect any loads between the Sunny Boy and the Sunny Multigate.

  • Do not connect any loads between the individual Sunny Boy inverters.

  • Do not open the lid of the Sunny Boy.

  • Only mount the Sunny Boy on the framework mounted on the roof directly under the PV modules or on the wall.

  • Do not mount the Sunny Boy directly on the module frame.

  • Do not mount the Sunny Boy on flammable construction materials.

  • Do not mount the Sunny Boy in areas containing highly flammable materials.

  • Do not mount the Sunny Boy in potentially explosive atmospheres.

All components must remain within their permitted operating ranges at all times.

The product must only be used in countries for which it is approved or released by SMA Solar Technology AG and the grid operator.

Sunny Multigate

The Sunny Multigate is a communication unit and forms the electrical connection point of the PV system with a maximum of twelve micro inverters to the utility grid. The Sunny Multigate is equipped with an integrated disconnection point for grid monitoring. The Sunny Multigate is connected between the micro inverters and the utility grid to feed the alternating current of the micro inverters collectively into the utility grid.

The product is designed for indoor use only.

The Sunny Multigate must be installed and operated in a distribution box.

  • A maximum of twelve micro inverters can be connected to the Sunny Multigate.

  • No loads must be connected between the Sunny Boy and the Sunny Multigate.

  • No loads must be connected between the Sunny Multigate and the circuit breaker.

  • The grounding conductor of the AC cable from the inverter must be connected to the Sunny Multigate.

  • The grounding conductor of the Sunny Multigate must be connected to the equipotential bonding of the AC distribution board.

  • The Sunny Multigate must not be opened.

All components must remain within their permitted operating ranges at all times.

The product must only be used in countries for which it is approved or released by SMA Solar Technology AG and the grid operator.
