SMA Sunny Boy Storage 3.7 – Grid-connected photovoltaic inverter 3.7 kW for storage (No Wi-Fi)

Sunny Boy Storage 3.7/5.0/6.0 is the powerful SMA battery inverter for private households. With up to three battery connections, even large storage systems can be created and the system can be flexibly expanded.

Solar Energy Storage - Expandable with additional storage power as needed
- Ideal for network connected systems
- Multi-string connection: Possibility to connect up to three high voltage batteries
- Integrated Secure Power Supply backup function
- Fully automatic backup function for the electricity supply of the entire house (optional)
- Integrated SMA Smart Connected service package for automatic monitoring of the battery inverter

Flexibility in system design - Always guaranteed power supply thanks to solar energy: today, tomorrow and in the near future
Finding the right combination of PV and storage is a personal matter that depends on aspects such as energy consumption and the user's home. If the family grows, if an electric car needs to be charged or if the garage becomes a workshop, the possibility of connecting up to three high-voltage batteries allows all loads to be powered by PV even when the sun is not shining.

New installation: photovoltaic system with storage
A storage system ensures independence from conventional electricity suppliers and rising energy costs.
Particularly efficient thanks to high-voltage technology, systems with Sunny Boy Storage are also easy to install.

Modernization: photovoltaic system with storage
In order to be able to cash in even more of the solar energy produced on site, an existing photovoltaic system can be expanded with just a few additional components into a perfect storage system. The operator thus further reduces the withdrawal from the grid and minimizes electricity costs.

Expansion: Adapting a storage system to increased demand
Thanks to multi-string technology, up to three high-voltage batteries can be connected to the Sunny Boy Storage at any time. This allows the storage system to be gradually expanded and adapted to individual needs.

Ease of Management - Quick start thanks to modern communication
- Ease of installation
- Quick commissioning thanks to the integrated web interface
- Constant updates thanks to the direct connection with Sunny Portal / Sunny Places
- Web user interface - Quick start thanks to modern communication

Reliable Power Supply - Reliable power supply, even in the event of a blackout
In the event of a blackout, the integrated Secure Power Supply backup function manually powers individual loads using the battery. An automatic switch is also available on request to power the entire home on all three phases via the battery and photovoltaic system in the event of a blackout. In backup mode, a power of up to 8 kW is available, sufficient to cover the needs of all major loads. 5-year warranty

Thanks to its high insulation class (IP65), it is able to withstand adverse environmental conditions and is therefore suitable for outdoor installation.
