4 OutBack - Ready For the New Grid Battery back-up and smarter inverter technology is in our DNA OutBack technology enables managing selfconsumption and seamlessly shifting between modes of operation based on energy storage

5 Grid/Hybrid system is 1. Fully-flexible and agile multi-mode operation Monitors hundreds of variables and manages energy flow from different directions Responds accurately, quickly and seamlessly 2. Built upon an energy storage system Three priorities: charging, running loads, managing the grid Built to handle outages 3. Equipped with multiple AC modes Sees several sources and can operate differently with each one Supports generators, mini-grid configurations, much more

6 Grid/Hybrid benefits: 1. Back-up power Provides essential services during outages and emergencies 2. Offset utility power Especially where the grid is unreliable, unstable, or ability to sell-back is limited (or may become limited) Excess renewable energy can power loads even when AC source is present 3. Enables Smart Consumption Manage utility energy flow according to the customer s desire

7 Systems using OutBack Power RESILIENT SOLAR

8 SunSmart E-Shelter Program 101 Florida Schools Emergency Shelters Provide uninterrupted power in the event of an emergency Harness solar energy to provide cost savings and subsidize electricity for schools Function as an educational tool through reporting scientific data for analysis by students The solar systems that were installed with OutBack Power backup equipment save these schools money on their energy bills by leveraging available solar power. In the event of an emergency, these systems also provide essential backup power to schools designated as shelters. -- Bill Young, Senior Research Engineer, FSEC

10 Grid-Interactive with Battery Backup 25kW residential solar power installation in Midwest Grid-interactive operation Exports excess power to grid Maintains batteries at full SOC Backup power for critical loads Refrigerators and freezers Lighting and communications Solar thermal water heater pumps Sump pumps Near-infinite runtime using solar

11 Grid-Interactive System, Kupillas Residence PV system offsets home s energy use, and provides energy security Customer lives at end of a utility transmission line Frequent power outages that can last for several days 7.2 kw system provides autonomy for critical loads Home business equipment Lighting Water pumping Coordinated SOC-based load shed managed by the system for extended power outages during inclement weather

12 After Japan s tsunami disaster, Mobile Solar dispatched MS-150 transportable power systems Able to operate independently, the systems powered key recovery assets Water purification Communications Construction tools Mobile Solar Disaster Recovery

13 Malankara Tea Plantation India s first Net-Zero energy building, with complex loads 18 tons of AC, water pumps, packing machines, lighting & IT Local utility service is overtaxed and sporadic Entire complex runs off the grid during extended outages Energy cost savings payback in less than five years 97% reduction in diesel fuel consumption 47 tons of carbon emissions savings per year

14 Critical Power at Hospital in Haiti Unreliable local grid prone to frequent power outages and disruptions Generator power noisy, expensive, and fuel is hard to obtain Without power, could not maintain standards of care Refrigerating medicine and vaccines Incubators and other medical devices Surgical lighting Today, solar energy provides more than 90% of the hospital s electricity Reliably powers critical electrical loads, even in the event of a power disruption The system gives the doctors and staff a healthier work environment, free from generator noise and diesel fumes

15 Solar Journey Solar EV Charging Zero-emission demonstration project of two Columbia University doctoral students Electric vehicle (EV) and solarequipped trailer Planned 3,200 mile drive across US Drove to Rockaway Beach to assist with Hurricane Sandy recovery Provided electricity to residents who were without power Powered Saint Gertrude Church s Thanksgiving-day dinner

16 EV Charging Integration EV charging can require substantial transmission upgrades to support demand Systems using OutBack Power s Radian inverter can defer expensive upgrade by providing energy buffer Support AC Input mode allows user to define maximum draw on an undersized feeder OEM customers have developed integrated PV generation and EV charging installations which provide both backup power to the facility as well as ancillary services to the utility AXS Port provides full command and control of all system parameters over Ethernet / Modbus/TCP

17 Advanced Capabilities Capabilities used to meet project requirements today: Power factor correction Power quality / power smoothing Peak shaving / load leveling Demand response / load shed EV fast charge buffer Infrastructure expansion deferral What Capabilities Would You Like?
