COST SAVING / REVENUE GENERATION
With a battery storage system:
Generate own Renewable Energy or buy
electricity from the grid when it is cheap – then
use or store in the battery
REVENUE GENERATION
COST SAVING
COST SAVING
• Use it yourself when electricity is expensive
• Replace a diesel generator for standby
power
• Sell it to others when electricity is
expensive

SMA System Solutions for storage applications
System Technology
• 12 SMA Sunny Islands
• 2 SMA Sunny Home Managers
• 2 Multicluster Box
• 4 Battfuse
Project information
• Installed battery power: 60 kW
• Battery supplier: Tesvolt
Project
• Location: London Borough of Hounslow
Commissioning: January/ February
2016
• Installer: Revolution
The London Borough of Hounslow has
unveiled what it claims to be the largest PV
array by a local authority, and the first to
incorporate battery storage.
The borough invested £2 million to install a
1.73MW array atop Western International
Market (WIM) near Heathrow with the
intention of turning it into a carbon-zero
attraction.
TECHNOLOGY NEEDED FOR MW SCALE STORAGE SYSTEMS

• Can be grid forming
• Connects directly into the sub station / distribution transformer at the enterprise
• Includes transformer and switch gear
• Compatible with different types of battery technologies
• Containerised System
TESVOLT POWER STORAGE
Benefits:
• Scalable from 0.5 MWh to 100 MWh
• Ready to connect for Battery Inverter Station
• SAMSUNG SDI Lithium Cells prismatic
• 10 Years power Warranty
• Transportable
• Containerised System

SMA system solutions for hybrid applications
System Technology
• 1 SMA Fuel Save Controller
• 1 Sunny Central Storage pre-installed in 1
MVPS
• 73 Sunny Tripower 25000TL-30
• Direct modbus connection to genset
controller
Plant information
• Installed PV power: 1.89 MWp
• Installed Storage capacity: 1 MW, 570
kWh
• Diesel capacity: 4 MVA
• Annual energy yield: 3,200 MWh
• Annual diesel savings: > 850,000
liters
Project
• Location: Dutch Caribbean Island of St.
Eustatius
• Commissioning: 2016
• Specific Requirements: Exposure to salty
air, hurricanes, fast
cloud movement
Today, solar energy covers 23% of St.
Eustatius’ total electricity need. To stabilize
the grid, which is influenced by fast power
fluctuation related to cloud movement, a
Li-Ion storage facility has been integrated
to absorb the fluctuations, provide energy
shifting and frequency stability functionality
also at night. Thanks to the SMA Fuel
Solution about 2,240 tons CO2 per year
can be saved. The project has been
designed, and implemented by the SMA
Sunbelt Energy GmbH.
BACK UP POWER
SUNNY CENTRAL STORAGE
• Medium voltage power station
• Includes transformer and switch gear
• Grid forming so works with no grid
• Provides back up power
• Low maintenance cost / very high reliability
DIESEL GENERATOR
• Used infrequently so reliability can be an issue
• High maintenance cost
• Low return on capital investment
EASE OF DEPLOYMENT
• Containerised solution
• Cost effective transport – ISO standard
container
• Temporary structure – No planning needed
• Connecting MV network
• Takes up two car parking spaces
• Pre wired and tested
ENVIRONMENTAL BENEFITS
• Battery storage inverter / Zero carbon
emissions
• No restriction on deployment compared to a
diesel generator (Not allowed to be deployed
in the city of London
• Can also be combined with PV system
