§ Tim Keating, SunSpec Alliance § Rolf Bienert, Technical Director, USNAP Alliance § Sebastian Hassell, Product Manager, Fronius
Inverter Communications Challenges R (Topic*) Discussions Template
² Open, modular communications for inverters are key for advanced grid service adoption and DER market growth
² Next-generation interconnect rules for distributed generation including CA Rule 21 and others intend to include communication capability…
² But… communication technologies are diverse across market sectors and best choices are uncertain
² And… Inverters have decades-long service lives, and communication technologies are evolving much faster
² And… It is uncertain when network connectivity to residential and commercial systems will need to be deployed
“Informa)on about energy will become almost as
important as energy itself”
DER - Where We’re Going
Unified Architecture
Build On Open SunSpec Specifications
² Devices ² Hardware integration
A Modular Approach t o Home Energy Management in t he “ I n t e rne t o f Th ings ”
USNAP & ANSI/CTA-2045
Standards, we've got lots of them...
UNIVERSAL POWERLINE ASSOCIATION
...and in the Internet of Things, every one of them has Use Cases that they do better.
Success fu l I ndus t ry Model
Universal Communications Module (UCM)
ANSI/CTA-‐2045
Modular Communica)on Interface (MCI)
Smart Grid Device (SGD)
The Interface • ANSI/CTA-‐2045 iden)fies a Universal Communica)on Module (UCM) and a Smart Grid Device (SGD).

CSI4 Modular Communication (MC) Technical Approach
Grid Network
Comm Module
Inverter
SunSpec Protocol, CTA-‐2045 Form Factor
Any protocol, any physical media, provided by any
stakeholder
Standardized Port Interface
Standardized Tes)ng
Value Proposi>on: Mass produce common models, and these models can work in any communica)on system.
CSI4 Making Integration Practical
NetworkProtocol Mapping Inverter
Protocol
Any Communica)on Network
(e.g. Wireless, PLC, Fiber)
Plug-‐In Interface to the Inverter
Value Proposi>on: Prac)cality. Communica)on system connect to any inverter brand using one modem design. A manageable and economical network to residen)al and commercial inverters can be built when needed.
Value Proposi>on: Flexibility. Any communica)on system can be used. Customers can independently monitor and manage their products. Aggregators and u)li)es can have access.
CSI4 Example Could be Any and All Inverter Brands
IEEE 1815/ DNP3
System C
Communication Systems Demonstrated
IEEE 2030.5
OpenADR
System A
System B
Inverter Brand A
Inverter Brand B
Interoperability Different physical layers and protocols
Different inverters, with same modular comm interface
DER Modular Communication Benefits
² Equipment manufacturers; i.g. inverters and communication modules: § Can capitalize on mass production driving down cost § Single interface for any platform (Cellular, ZigBee, Wi-Fi etc.) using SunSpec information models § Provides a certification platform for advanced grid feature control § Allows for end user/customer to customize communications platform, protocol, and security § Allows integration and interface with multiple demand response and home automation platforms
² Large integrators, small integrators and aggregators: § Allows a single standard or custom standard communications module for any inverter § Allows customized or standard backend platform development § Allows monitoring of inverter data, and control of advanced grid features § Simplified fleet management by the removal of tech obsolesce risk as technology changes
² Monitoring and aggregator companies: § Can customize modules to their services, and monitor/ control aggregated fleets § Can cater to the smaller installation companies by providing standard low-cost modules
² Finance and investment partners: § Allows lower cost integration of fleets of distributed resources increasing the value of the assets
² Utilities: § Customize modules to meet platform, protocol, and security demands; can provide grid support by
aggregating fleets of distributed resources. Can integrate into AMI networks.
SunSpec CTA 2045 Inverter Modular Communication Workgroup
² Isolate compute platform evolution from power conversion platform
² Focus on inverter integration issues
² Looking for broad collaboration with industry partners
SunSpec Workgroup Advice* Getting Started
² Understand your charter and how it fits into SunSpec effort
² Make sure you have support from the right SunSpec folks
² Make sure you have broad industry support if possible § Can be a challenge!
² Recognize that these efforts are often a marathon, not a sprint § Develop a reasonable rhythm * Andrew Miller – 1Energy, SunSpec Member Meeting, March 15, 2016
Start-up Inverter MC Workgroup
² Hold informational meetings: today is first one! ² Weekly meetings, begin week of May 2; ² Day/time? ² Validate Inverter MC WG Effort is Needed
² Does Inverter industry need a modular, standard communication interface?
² Other options: USB3? Ethernet and gateway? ² If so what needs to change?
Inverter MC Workgroup Next Steps…
² Strawman charter to be validated: § CTA 2045 is needed; Workgroup defines mechanical,
electrical and physical layer or layer 1 interface for inverters
² Recruit needed support in next weeks… ² Who do we need? Equipment Mfg’s., Integrators, Fleet
Operators, Utilities, Aggregators, Etc. ² Draft workgroup plan w/ critical mass and charter ² Validate: Go/no for continuation Inverter Modular
Communications Workgroup in 6 weeks ² What are we missing?
Inverter MC Workgroup Next Steps…

Some of the Questions and Issues
² Does Inverter industry need a modular, standard communication interface? ² e.g. Ethernet/RJ-45, Serial/RS-485/DB-9 ² Other options: USB3? Ethernet and gateway?
² CTA 2045 DC or AC? ² AC: requires AC power and large format ² DC: Power to plug; insufficient for cellar modem? need extension? ² Global issues among others, un-ordered
² External accessibility probably required(or plastic shielding) ² “No Link Layer Mode” for inverters ² Wireless antenna considerations ² 3rd Party installation considerations ² Weather proofing considerations ² Physical security ² Who will be key to get to join the effort?
