SMA Sunny Boy Storage System

Bookmark and Share

The ideal way to add storage to any new or existing solar PV installations. The inverter is AC coupled and connected into the building distribution and installed just like any PV string inverter. However, instead of a PV array providing the DC input a high voltage DC battery is used.

  • Works with string and module inverters
  • Easy to install
  • Low-cost
  • Capability to upgrade almost any PV system
  • Allows automatic load control
  • Self-consumption is maximised
  • Backup possible (SBS3.7-6.0)

What's needed (in addition to normal PV system):

  • A Sunny Boy Storage inverter
  • HV Battery  - eg. LG CHem HV to store the energy
  • SMA Energy Meter or Home Manager 2.0 and current transformer
Basic System

SMA Sunny Home Manager

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. Edimax Smart Plug Switches can also be used to monitor and control loads.

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

SMA Energy Meter

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.

  • 63A rating - use with external current transformers for higher currents (see related products)
  • Warranty: 2 years
