2 WAYS TO MEET 2017 NEC 690.12 RAPID SHUTDOWN
February, 2020
Featuring Floating Solar with Tigo
❖ Introduction
❖ What is rapid shutdown? NEC Article 690.12
❖ Why Tigo TS4 is your most cost-effective RSD solution
❖ Floating Solar with Tigo
❖ Conclusion
Agenda
Introduction to Tigo
❖ Founded 2007
❖ HQ in Silicon Valley, CA
❖ Sales and support teams worldwide
❖ 3M+ units shipped, products certified
across many countries, installed on 7
continents
❖ Supported by all US string inverter

Mission Statement
To increase customer ROI
by delivering smart PV technology
designed to yield maximum energy harvest
at minimal cost
What are the Rapid Shutdown requirements?
NEC 2014: Early Rule Making
❖Rapid Shutdown▪ Only applies to PV conductors
more than 1.5m/5ft in length within a building or more than 3m/10ft from a PV array
▪ Not more than 30V and 240 VA within 30 seconds (originally 10 seconds)
Under 30V In 30 seconds
10ft/3m
600V OK
NEC 2017: Now in Effect in Most AHJs
The array boundary:
“350mm/1ft from the array in all directions”
• Outside array boundary• Controlled conductors limited to
not more than 30 volts within 30 seconds
• Inside array boundary• Field labeling required
• Controlled conductors limited to not more than 80 volts within 30 seconds
• If no exposed wiring methods, conductive parts installed more than 2.5m/8ft from ground = no need to comply
1ft/350mm
Under 30VIn 30 seconds
Under 80V
In 30 seconds
❖ Each module has a device which
limits its output voltage
❖ There is a rapid shutdown initiation
device (an on/off switch) to tell the
devices when to shutdown
What do RSD-compliant systems look like?
RSD switch (initiator)
RSD device on
each module
How can Tigo help?
Why Tigo for your RSD projects?
❖ Flex MLPE lets you pay only for what you need
❖ The only manufacturer with selective deployment
❖ Compatible in on or off grid systems with hundreds of
inverters
❖ The Smart Module: Built in Functionality
TS4 (Integrated)
Architecture 1: TS4 (Integrated) Architecture 2: TS4-A (Add-on)
❖ Add to any module, new or existing
Meet Rapid Shutdown with TS4❖ Select smart module functions as needed for reduced cost and increased ROI
TS4-S TS4-O
Safety Optimization
TS4-F
Fire Safety
Two Architectures for Rapid Shutdown with TS4
TS4-F: Fire Safety
Diodes Fire Safety
Functionality: Fire Safety ( )
❖ NEC 2017 rapid shutdown compliance
❖ Simplest installation
❖ UL-certified with leading inverter
manufacturers
❖ Integrated with module and inverter
vendors
❖ Simple, easy to install rapid shutdown
solution
❖ How it works:
1. The RSS Transmitter sends a “keep-alive”
signal to the TS4-F
2. Removing power from the RSS transmitter removes “keep-alive," initiates shutdown
❖ What’s needed:
1. 1x TS4-F per module
2. 1x RSS transmitter integrated inverters or
external RSS transmitter kits
on each module
RSS TransmitterAvailable standalone or built-in to inverter
TS4-A-2F (Q2 2020)
❖ Like having 2 TS4-A-Fs in one package
❖ Starts shipping end of Q2 CY2020
❖ Ratings:
❖ 1000W (500W per channel)
❖ 16-90V, 15A (per channel)
TS4-A-2F (Q1 2020)
Tigo RSS Transmitter for TS4-F
❖ Transmits keep-alive signal
to optimizers via PLC
❖ Accepts DC conductors in
its core(s)
❖ Power supply: 12V, 2A
❖ Max current: 150A/core
❖ Dual core version
available
RSS Signal Detector
❖ Functionality testing device for
sending the PLC Rapid Shutdown
Signal with TS4-F
❖ Handheld tool used during
installation to verify the keep-alive
signal from the RSS Transmitter
❖ Ensures safe and smooth
installation and maintenance
TS4-S/O: Safety, monitoring, optimization
Functionality: Safety ( )
❖ NEC 2017 rapid shutdown compliance
❖ Includes Module-level monitoring for
reduced O&M/OPEX costs
❖ UL-certified with leading inverter
manufacturers
❖ Automatic or manual shutdown
Diodes Monitoring Safety Optimization Long Strings
Functionality: Optimization ( )
❖ Achieve higher energy yields with PIV
❖ Lower system cost with Selective Deployment
❖ The only platform displaying Reclaimed Energy• Tigo shares the actual ROI of optimization in kWh
❖ Includes all benefits of safety / monitoring
Diodes Monitoring Safety Optimization Long Strings
Deploy where needed = save $$$
❖ Rapid shutdown, plus monitoring,
optimization
❖ How it works:
1. The TAP sends a “keep-alive” signal to
the TS4’s (wireless)
2. Removing power from the CCA and TAP
removes “keep-alive”, initiates shutdown
❖ What’s needed:
1. 1x TS4-S/O per module
2. 1x TAP per up to 300 modules
3. 1x CCA per up to 900 modules
on each module
❖ Tigo is the only multi-vendor UL-certified rapid shutdown solution

• Degradation & Mismatch Mitigation
• Optimizers will mitigate not only aerial shading but also
obstructions from salt water soiling and seabird droppings.
• Bifacial backsheet Irradiance
• Optimizers will mitigate mismatch of front & back sheet
irradiance.
DID YOU KNOW? Tigo TS4 units are IP68 rated. This guarantees protection in water up to 1.5m deep,
a critical characteristic in stormy conditions, abnormal high tides, or temporary submersion.
• Short Circuit Detection
• Tigo’s optimizers can detect and automatically shut off strings
with short circuits. This is very helpful if a module/string/array sinks
so it doesn’t affect the rest of the system.
• Monitoring from Land
• Tigo’s optimizers include wireless module-level monitoring so
O&M can be done on land via our SMART Website/App.
• Automatic Safety
• Tigo’s optimizers include safety so automatic shutdown, over-
temperature production, heat dissipation, etc. are included.
