3 Agenda > Who is SMA > SMA Sunny Boy SPS PV Direct Backup Solution > Sunny Island Energy Storage Solution

4 The Global Leader, and #1 in North America > $2B+ in annual revenue > 5,000 employees worldwide > Represented in 21 countries > 11.5 GW total manufacturing capacity > 25 GW+ installed > North American production in Denver and Toronto > The world leader in solar inverter technology, service and support > Solutions for all power classes and applications > Highest efficiency (99 %)

5 SUNNY BOY 3000/4000/5000TL-US

6 Solar Power: No grid, no batteries, no problem.

7 Not Just an Inverter, a Home Energy Solution > Extension of field-proven Sunny Boy line > Unique features not available from any other manufacturer > System design flexibility and installation simplicity make the TL-US the first choice among installers > The TL-US is an evolutionary leap forward, paving the way for complete home energy management > European experience with the smart home has earned SMA America the leadership role in the U.S. energy transition > Maximum power production, leading communications solutions and detailed monitoring make the TL-US the first choice among homeowners

8 SMA Sunny Boy 3000/4000/5000 TL- 22-US > Grid interactive, transformerless, solar inverter. > 3, 4, 5, kva > DC Protections-AFCI, GFDI, insulation testing, RISO-ungrounded system. > AC Interface- PF, Grid Manage, Cluster controller > SPS-Secure Power Supply- 120V voltage source to dedicated outlet. PF

9 A New Generation of Innovation MPP voltage Maximum power production 175 V to 480 V OptiTrac Global Peak Operating temp -40 F to +140 F Flexible design and simple installation Dual MPP Trackers Simplified DC Wiring Leading monitoring and communications Plug-and-play Webconnect Sunny Portal Monitoring Groundbreaking new features ZigBee Communication Secure Power Supply

10 Features & Highlights Dual MPP Trackers Exceptional flexibility and energy harvest CEC 97.0% OptiTrac Global Peak Highest practical use DC AFCI Ethernet Connectivity New features & USP s -40 C +60 C Emergency Power Supply

11 Opportunity power when it matters most > State of the art technology allows PV operation when grid is lost > Dedicated outlet powered with up to 1500W

12 Secure Power Supply (SPS) Innovative Stand-Alone Power Solution > Inverter can be switched to stand-alone operation during prolonged grid outages Example of Secure Power Supply installation > Access to power as long as the sun shines > No costly batteries or storage > Enhanced homeowner security, comfort and peace of mind Blackout > Not available from any other inverter manufacturer, another first for SMA SPS ON / SPS OFF Max 1,500 W Power socket with switch (installer supplied)

13 Secure Power Supply (SPS) Disconnection after grid loss and setup of stand-alone system Example of Secure Power Supply Installation Re-direction of PV electric power to an external power socket Activation of electric power (EPS ON) and returning to feed-in operation (EPS OFF) by external switch Blackout Supply power to battery chargers, phone chargers, TV, PC, AC/DC power supplies, etc. during grid outages (during daylight) Power Socket with Switch V max.12 A SPS ON / EPS OFF

14 Simple, Safe Operation > Switch provides signal to relay indicating receptacle is ready to receive power when grid is down. > Homeowner activated > Relay will not activate if grid is available > Failsafe grid tie operation in the morning if the grid returns at night

15 SPS Technical Overview > Maximum output voltage=125 VAC > Maximum output current=12 A > Maximum output power=1500 W The SPS is limited by the instantaneous insolation levels of the solar modules- NO STORAGE. If the load exceeds the power generated a relay opens and the inverter reconnects in 20 seconds.

16 SPS Function Flowchart gridinteractive mode inverter is connected to the grid SPS mode inverter supplying power only to the connected dedicated outlet 20sec wait inverter not feeding any power anywhere, after timer expired retry with voltage-ramp-up

17 Grid Interactive Mode = ~ Grid Detected Grid Monitoring EPS Logic DC Disconnect 0 V EPS 240 V Switch EPS Outlet

18 EPS Mode = ~ Grid Blackout No Grid Detected Grid Monitoring EPS Logic DC Disconnect 120 V EPS 0 V Switch EPS Outlet User must manually turn ON (close) to initiate EPS operation

19 Switch Line Neutral Ground If present, remove tab to separate switch and outlet wiring

20 Secure Power Supply (SPS) Innovative Stand-Alone Power Solution > Power from PV array is directed to a dedicated wall outlet with max load of 1,500 W > Provides stand-by power to charge phones, tablets, personal computers, batteries for flashlights, radios, etc.

21 First Grid Interactive/ SPS system installed at SMA

22 Sunny Island- Product Introduction

23 Sunny Island- Product Introduction > Versatile grid-interactive battery based inverter designed for off-grid and backup power applications. > Rated at 4.5 and 6.0 kw > Utilizes a 48 Volt battery bank > Not a typical charge controller that uses DC electricity from PV array to charge batteries! NO PV is connected directly to Sunny Island > Superior management of battery bank and other sources of AC power, this is referred to as AC coupling > SMA pioneered the AC-coupling concept, since 2001

24 AC Coupling: The Benefits > Planning > Flexibility > Components > Expandable

25 Sunny Island- Basic Tasks/Functions > Creates a Micro Grid when utility fails > Supplies and controls frequency and voltage > Transfers and converts energy in both directions > AC to DC for battery charging > DC to AC to supply energy to loads > Controls external loads and energy sources > Load shedding > Power control of Sunny Boys, auto generator start /stop

26 Sunny Island- Product Platform

27 Sunny Island- Capabilities > Feed Renewable energy to the utility when grid is present (if desired) > Battery Backup Power supply during short or long term grid failures > Transparent near UPS switching times (16 ms) > Not fast enough for critical loads such as Life support, Bank UPS > Charge and maintain battery when grid returns

28 No grid no problem

29 We have scalable solutions to fit today

30 Sunny Island- Control Scheme AC Coupling: Sunny Island creates the grid(voltage/hz) source PV Production powers protected loads panel, passes thru SI, maintains battery SOC, feeds main panel and back feeds grid

31 Sunny Island- No Grid no problem AC Coupling: Sunny Island creates the grid(voltage/hz) source SI opens relay, preventing grid back feed. Mimics grid to keep SB/PV producing power Runs Backed up Loads If loads>pv, then draws down battery If PV>Loads then Frequency shift power control
