3 System Description SMA Solar Technology AG


3 System DescriptionThe SMA Flexible Storage System is intended to support increased self-consumption through the following measures:

Buffering of excess PV energy with battery

Plant monitoring and load control with Sunny Home Manager

The Sunny Island uses the connected battery to buffer excess PV energy. Via the Sunny Home Manager, the Sunny Islandreceives the data of the connected energy meter and thus records feed-in and purchased electricity. Based on this data,the Sunny Island battery management regulates the charging and discharging of the battery.

The Sunny Home Manager receives location-based weather forecasts via the Internet and uses them to create a yieldforecast for the PV plant. In addition, the Sunny Home Manager detects how much energy is typically consumed atcertain times in a household and uses this to create a load profile of the household. The Sunny Home Manager uses theyield forecast and the load profile to determine favourable times for increasing the self-consumption rate and switchesthe electrical loads connected to the SMA radio-controlled sockets on and off as necessary. If required by the networkoperator, the Sunny Home Manager also monitors the active power feed-in of the PV plant. If the network operator'smaximum permissible value for active power feed-in is exceeded, the Sunny Home Manager sends power reductioncommands to the SMA PV inverters. The PV plant can consist of PV inverters with Bluetoothcommunication and PV

inverters with Speedwire communication.

7 Basic Configuration of the Sunny Island

Requirements:

The SMA Flexible Storage System must be installed in accordance with to the circuitry (see Section 4)(see the installation manuals of the individual devices and components).

In the distribution board, the miniature circuit-breaker F1 must be open.

Danger to life due to fire or explosion

Danger of fire due to a battery if the lithium-ion battery is incompatible with Sunny Island. With incompatible lithium-ion

batteries, it is not ensured that the battery management will protect the battery. Ensure that the battery is from one of the following manufacturers and has been approved for Sunny Island by the

manufacturer:

Akasol

Dispatch Energy

LG Chem

Leclanch

SAFT

Samsung

SonyThe list will be updated regularly (see Technical Information "Planning Guidelines Increased Self-Consumptionwith Sunny Island/Sunny Home Manager" at www.SMA-Solar.com).

Damage to the battery due to incorrect settings

The parameters for the battery influence the charging behaviour of the Sunny Island. The battery is damageddue to incorrect setting of the parameters for battery type, nominal voltage and capacity.

During the basic configuration, ensure that you configure the battery values recommended by the battery

manufacturer (for the battery technical data, see the documentation of the battery manufacturer). In the basic configuration, configure the battery capacity for a ten-hour electric discharge (C10).
