Intended Use
The Sunny Boy Storage is an AC-coupled battery inverter for parallel grid and stand-alone mode
operation. The Sunny Boy Storage converts the direct current supplied by a battery into grid-
compliant alternating current. The Sunny Boy Storage, together with a battery and a compatible
energy meter, make up a system for increased self-consumption (Flexible Storage System) or,
together with a automatic transfer switch compatible with Sunny Boy Storage, a battery-backup
system (Flexible Storage System with battery-backup function).
The product must only be used as stationary equipment.
The product is suitable for indoor and outdoor use.
The product must only be operated in connection with an intrinsically safe lithium-ion battery
approved by SMA Solar Technology AG. An updated list of batteries approved by SMA Solar
Technology AG is available at www.SMA-Solar.com.
The battery must comply with the locally applicable standards and directives and must be
intrinsically safe (see technical information "SMA Flexible Storage System - Detailed explanations of
the safety concept" 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.
The product is not suitable for supplying life-sustaining medical devices. A power outage must not
lead to personal injury.
All components must remain within their permitted operating ranges and their installation
requirements 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.
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)
• HM-20 (Sunny Home Manager 2.0)
The product may only be operated in battery-backup systems using an automatic transfer switching
device approved by SMA Solar Technology AG. You are not allowed to build automatic transfer
switching devices for operation with this product by yourself on the basis of a circuit diagram.
