SMA Sunny Boy Storage 3.7 – Photovoltaic inverter for grid connection 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 homes. With three connections per battery it is possible to create even rather large storage systems and flexibly expand the system.

Solar energy storage - Possibility of expansion with additional storage power as needed
- Ideal for network connected systems
- Multistring connection: Possibility of connecting up to three high voltage batteries
- Built-in 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

System design flexibility - Always guaranteed power thanks to solar energy: today, tomorrow and in the near future
Finding the right combination of photovoltaic system and storage system is a personal question that depends on aspects such as energy consumption and the user's home. If the family grows, if you need to charge an electric car or if the garage becomes a workshop, the possibility of connecting up to three high voltage batteries allows you to power all the loads through photovoltaic current even when the sun isn't shining.

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

Modernization: photovoltaic system with storage 
To be able to exploit an even greater quantity of solar energy produced on site, with just a few additional components, it is possible to expand an existing photovoltaic system, transforming it into a perfect storage system. In this way, the operator reduces the withdrawal from the grid even further and reduces electricity costs to a minimum.

Expansion: adaptation of a storage system to the increase in demand 
Thanks to multistring technology it is possible to connect to Sunny Boy Storage at any time. up to three high voltage batteries. In this way the storage system can be progressively expanded and adapted to personal needs.

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

Reliable electricity supply - Reliable electricity 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 house on all three phases via 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 the main loads 5-year warranty

Thanks to the high insulation class (IP65) it is able to face unfavorable environmental conditions and is therefore suitable for outdoor installation.
