TS4 UHD-Core with TAP and CCA

IMPORTANT SAFETY INSTRUCTIONS

LETHAL VOLTAGE MAY BE PRESENT IN ANY PV INSTALLATION

SAVE THESE INSTRUCTIONS

• This manual contains important instructions for installation and maintenance of the Tigo
product models TS4-L, TS4-O, TS4-S, TS4-M, TS4-A-O, TS4-A-S, TS4-A-M, TS4-A-O-Duo, TS4-A-S­Duo, TS4-A-M-Duo, TS4-R-O, TS4-R-S, TS4-R-M, TS4-R-O-Duo, TS4-R-S-Duo, TS4-R-M-Duo, Tigo
Access Point (TAP), Cloud Connect Advanced (CCA), and related Tigo software and
mobile applications.

• Risk of electric shock, do not remove cover, disassemble, or repair, no user serviceable
parts inside. Refer servicing to qualied service personnel.

• Before installing or using the Tigo System, please read all instructions and warning
markings on the Tigo products, appropriate sections of your inverter manual,
photovoltaic (PV) module installation manual, and other available safety guides.

• Failure to adhere to these instructions may result in injury or death, damage to the
system, or voiding the factory warranty.

• To reduce risk of re and shock hazard, install this device with strict adherence to
National Electric Code (NEC) ANSI/NFPA 70 and/or local electrical codes. When the
photovoltaic array is exposed to light, it supplies a DC voltage to the Tigo TS4 units. The
TS4 units start in the “ON” state and their output voltage may be as high as the PV
module open circuit voltage (VOC) when connected to the module. The installer should
use the same caution when handling electrical cables from a PV module with or without
the TS4 units attached.

• Installation must be performed by trained professionals only. Tigo does not assume
liability for loss or damage resulting from improper handling, installation, or misuse of
products.

• Remove all metallic jewelry prior to installing the Tigo TS4 units to reduce the risk of
contacting live circuitry. Do not attempt to install in inclement weather.

• Do not operate the Tigo TS4 units if they have been physically damaged. Check existing
cables and connectors, ensuring they are in good condition and appropriate in rating.
Do not operate Tigo TS4 units with damaged or substandard wiring or connectors. Tigo
TS4 units must be mounted on the high end of the PV module backsheet or racking
system, and in any case above ground.

• Do not connect or disconnect under load. Turning off the Inverter and/or the Tigo
products may not reduce this risk. Internal capacitors within the inverter can remain
charged for several minutes after disconnecting all power sources. Verify capacitors
have discharged by measuring voltage across inverter terminals prior to disconnecting
wiring if service is required. Wait 30 seconds after rapid shutdown activation before
disconnecting DC cables or turning off DC disconnect.

• Always assume TS4 units are in “ON” state, or may turn on when restarting.

• The CCA must be on the same AC branch circuit as the inverter to meet rapid shutdown
requirements.

User PV-Off Warning

• A blinking green and yellow LED
indicates that PV-Off mode was
activated manually.

• A solid yellow LED indicates that:
Discovery has not been run,
Discovery completed but did not
find all expected TAPs or TS4 units, or
CCA is not able to upload data.
Connect to the CCA using the Tigo

PV PANELS

TS4-L, TS4-O, and TS4-S (includes TS4-R and TS4-A add-on versions)
with Cloud Connect Advanced and TAP are a solution to meet the
NEC 2014 & 2017 690.12 Rapid Shutdown requirements.

TS4 units with the safety feature automatically enter rapid shutdown
mode when the CCA is switched off and resume energy production
when power is restored to the CCA.

Wait 30 seconds after rapid shutdown activation before disconnecting
DC cables or turning off DC disconnect.

Test your rapid shutdown system by switching off the AC power to the CCA.

TS4 units with the safety feature will reduce their output to 0V when the CCA
is powered off.

STRING SIZING WITH TS4-L

TS4-L has a state of the art technology designed to reduce balance of system
costs by allowing longer strings. This can reduce the number of strings by up
to 30%, which directly correlates to a 30% reduction in combiner boxes, wiring,

fuses, and hardware overhead costs, as well as reducing the labor

requirement for installation.

By code:

Verify string VMPlimits by dividing inverter max MPP voltage range by the Smart Module's VMP.
From the example above: 510V ÷ 30.6V = 16 modules per string by inverter

In case of discrepancy between the code requirement and the inverter voltage
requirement pick the lower number of the two. Therefore, this example results in a maximum
of 16 panels per string, a 33% increase in string power, with a corresponding reduction in
electrical BOS costs.
