SMA Sunny Boy Storage System

The Sunny Boy Storage battery inverter is suitable for high-voltage batteries and is ideally suited to the electricity demand of a private household. It combines the flexibility of AC coupling with the advantages of high-voltage technology, enabling a significant reduction in system and installation costs.

Integrated web server and direct portal access, allows simple commissioning and monitoring of energy flows in the household.

Specifications:
Power (charge/discharge):  2,5 kW
DC-Voltage (Battery):  120 V – 500 VDC
DC-Current (Battery): 10 A
Efficiency (max.):  97 % (Battery to Grid)
Warranty: 10 years

The SMA Sunny Boy Storage 3.6-6.0 offers similar funtionality to the 2.5 but is also the first battery inverter with a multistring battery connection. Up to three different high-voltage batteries can be connected to a single inverter, for larger batteries three DC inputs can be connected in parallel.

This Sunny Boy Storage offers integrated emergency power, which can be switched manually. Back-up for a household supply can be provided using an optional additional automatic transfer switch.

Featuring an integrated webserver commissioning via smartphone or laptop is possible and household energy flows are easily visualised thanks to the direct connection to Sunny Portal and Sunny Places.

One Battery-Box Premium HVS is composed of 2 to 5 HVS  battery modules (2 to 4 with the SMA Sunny Boy Storage Inverter) together with a BCU and Base, that are connected in series to achieve a usable capacity of 5.1 to 12.8 kWh.
Additionally, direct parallel connection of up to 3 identical Battery-Box Premium HVS allows a maximum capacity of 38.4 kWh.
Ability to scale by adding HVS modules or parallel HVS stacks later.

• Capable of High-Powered Emergency-Backup and Off-Grid Functionality
• Highest Efficiency Thanks to a Real High-Voltage Series Connection
• The Patented Modular Plug Design Requires no Internal Wiring and Allows for Maximum Flexibility and Ease of Use
• Cobalt Free Lithium Iron Phosphate (LFP) Battery: Maximum Safety, Life Cycle, and Power
• Compatible with Leading 1 and 3 Phase High Voltage Battery Inverters
• Two Distinct Modules to Cover the Complete Range of System Sizes
• Highest Safety Standards like VDE 2510-50
• IP55

Temperature derating: The BYD HVS only minimally derates at low temperature.

Note: Commissioning the battery requires a device capable of running the BYD Be Connect App - available for the Apple App Store and Google Play Store.

The Sunny Home Manager is the ideal solution for simple plant monitoring and intelligent energy management. It provides remote monitoring via the SMA Sunny Portal and an overview of all the energy flows taking place in the household. It displays recommended actions and is able to control loads via SMA radio-controlled sockets automatically. The device learns the typical consumption pattern of the household and combines this information using a weather forecast prediction of the PV generation. As a result, the Sunny Home Manager enables a much higher proportion of generated electricity to be consumed on site and a highly efficient use of energy.

The Sunny Home Manager 2.0 includes an integrated Energy Meter to monitor the properties import/export.

Can be used in conjunction with Mennekes Amtron car charging points to provide optimal charging of EV's. 

Current Transformer clamps can be used to simplify installation and are required for systems where the main AC supply exceeds 63A per phase.

The SMA Energy Meter is a fast bidirectional single or three phase meter used to measure power going in/out of the grid. It communicates these values quickly via Speedwire using standard Ethernet cable to the Sunny Home Manager, or to the Sunny Boy Smart Energy.This, in turn, facilitates optimal energy monitoring, effective load and battery management and reliable active power limitation at the grid feed-in point while taking self-consumption into account.
