Intended Use

The Sunny Boy Smart Energy is a single-phase, transformerless hybrid inverter with 3 PV inputs (SBSE3.6-50 / SBSE4.0-50 / SBSE5.0-50 / SBSE6.0-50) or with 4 PV inputs (SBSE8.0-50 / SBSE9.9-50) and a battery connection. The inverter feeds the direct current from the PV modules into the connected battery or converts it to grid-compliant alternating current and then feeds it into the utility grid. The Sunny Boy Smart Energy also converts the direct current supplied by the battery into grid-compliant alternating current. In a system with additional PV inverters, the Sunny Boy Smart Energy can convert the alternating current generated by the PV inverters into direct current and feed it into the battery.

The Sunny Boy Smart Energy has a manual emergency power supply function (Secure Power Supply). When needed, in the event of a power outage, the Sunny Boy Smart Energy can continue to supply selected loads with electricity from the battery and the PV system by means of a socket connected to the inverter.

The product is intended for use in residential and industrial environments.

The product must only be used as stationary equipment.

The product is suitable for indoor and outdoor use.

The product must only be operated with PV modules of protection class II in accordance with IEC 61730, application class A. The PV modules must be compatible with this product.

The product is not equipped with an integrated transformer and therefore has no galvanic isolation. The product must not be operated with PV modules or batteries whose outputs are grounded. This can cause the product to be destroyed. The product may be operated with PV modules whose frame is grounded. The product may be operated with batteries whose enclosure is grounded.

PV modules with a high capacity to ground must only be used if the coupling capacity of all PV modules does not exceed 1.54 µF (SBSE3.6-50 / SBSE4.0-50 / SBSE5.0-50 / SBSE6.0-50) or 2.30 µF (SBSE8.0-50 / SBSE9.9-50) (for information on determining the coupling capacitance, see technical information "Leading Leakage Currents" at www.SMA-Solar.com).

The product may only be operated in connection with a lithium-ion battery approved by SMA Solar Technology AG. An updated list of batteries approved by SMA Solar Technology AG can be found in the system manual at www.SMA-Solar.com.

The battery must comply with the locally applicable standards and directives and must be intrinsically safe (see technical information "Safety Concept for Battery-Storage System" for detailed explanations regarding the safety concept of battery inverters by SMA Solar Technology AG).

The communication interface of the battery used must be compatible with the product. The entire battery voltage range must be completely within the permissible input voltage range of the product. The maximum permissible DC input voltage of the product must not be exceeded.

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

The product is not suitable for supplying life-sustaining medical devices. A power outage must not lead to personal injury.

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

The installation of the product in Brazil must meet the current technical standards for "Electrical installations of photovoltaic arrangements" (NBR 16690) and the "Managing fire risk related to photovoltaic (PV) systems on buildings" (IEC 63226).

The product may only be operated with one of the energy meters approved by SMA Solar Technology AG. The following energy meters are allowed to be used when operating this product:

  • EMETER-20 (SMA Energy Meter)

  • EM-1CT63A-21 (Energy Meter CT with 1 CT terminal)

  • EM-3CT63A-21 (Energy Meter CT with 3 CT terminals)

  • HM-20 (Sunny Home Manager 2.0)

The products by SMA Solar Technology AG are not suitable for use in

  • Medical devices, in particular products for supplying life-support systems and machines,

  • Aircraft, the operation of aircraft, the supply of critical airport infrastructure and airport systems,

  • Rail vehicles, the operation and supply of rail vehicles and their critical infrastructure.

The above list is not exhaustive. Contact us if you are unsure whether products by SMA Solar Technology AG are suitable for your application.

Use SMA products only in accordance with the information provided in the enclosed documentation and with the locally applicable laws, regulations, standards and directives. Any other application may cause personal injury or property damage.

The documentation must be strictly followed. Deviations from the described actions and the use of materials, tools, and aids other than those specified by SMA Solar Technology AG are expressly forbidden.

Alterations to the SMA products, e.g., changes or modifications, are only permitted with the express written permission of SMA Solar Technology AG. Unauthorized alterations as well as failure to observe the documentation will void guarantee and warranty claims and in most cases terminate the operating license. SMA Solar Technology AG shall not be held liable for any damage caused by such changes.

Any use of the product other than that described in the Intended Use section does not qualify as appropriate.

The documentation supplied is an integral part of SMA products. Keep the documentation in a convenient, dry place for future reference and observe all instructions contained therein.

This document does not replace any regional, state, provincial, federal or national laws, regulations or standards that apply to the installation, electrical safety and use of the product.
