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

brands

❖ Mission: Increase your ROI by

delivering smart PV technology

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

• Compatible: Dozens of manufacturers have tested the TS4

• Flexible: Installed with 2000+ types of inverters & charge controllers

• 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.
