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 Energy®
product models TS4-F, TS4-R-F, and the RSS Transmitter.
•Risk of electric shock, do not remove cover, disassemble, or repair, no user serviceable parts inside.
Refer servicing to qualified service personnel.
•Before installing or using the Tigo Energy® System, please read all instructions and warning markings
on the Tigo Energy 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 fire 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

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 Energy 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 Energy TS4 units to reduce the risk of
contacting live circuitry. Do not attempt to install in inclement weather.
•Do not operate the Tigo Energy 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 Energy TS4 units with damaged or substandard wiring or connectors. Tigo Energy 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 Energy 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.

1.3.1 SYSTEM OVERVIEW: TS4-F
Inverter
TS4 Smart Module
Powered by Tigo
The TS4-F requires a Tigo RSS Transmitter or inverter with built-in transmitter for
operation.
The Tigo RSS Transmitter is installed in line with a solar PV inverter, as shown,
and can be installed inside the inverter or external to it.
Method of Operation
TS4-F and TS4-R-F units start in the OFF position and measure 0.6V at the output.
When power is supplied to the RSS Transmitter, the TS4-F/TS4-R-F units turn ON
and allow full PV module voltage.

sending every TS4-F/TS4-R-F into shutdown mode with output reduced to 0.6V.

Add-on
Powered by Tigo
•TS4-R mounting is recommended on the upper right as shown, but can be
placed on upper left if needed (due to racking constraints, etc.)
•TS4-R cable glands must not be facing up.
•Allow clearance between PV module and mounting surface for air
circulation around TS4-R.
•Do not drill additional mounting holes in the frame or metal bracket.
RSS Transmitter
Note: connect modules to TS4-R inputs before connecting outputs

2.1 RSS INSTALLATION NOTES
•TS4-F and TS4-R-F are shipped in the OFF position and will
measure 0.6V at the output when the keep-alive signal is not
present.
•Failing to follow the sequence of installation steps may result in
TS4 damage not covered under warranty.
•Connect all TS4-R-F units to their respective modules before
connecting their outputs in series.
•Install all TS4-F or TS4-R-F units before powering on the RSS
Transmitter.
•Never apply an external voltage source to a module or string
equipped with TS4-F/TS4-R-F units.
•If parallel string connections are needed, first connect the TS4-F/TS4-R-F to
the PV modules, then connect all TS4-F/TS4-R-F outputs in series, and finally
pass one side (+ or -) of the homeruns through the PLC transmitter to turn
the system ON.
•Place rapid shutdown system label no more than 1m (3ft) from
initiator (AC disconnect) or service panel containing means of
disconnection if not at same location.
Place Rapid Shutdown System label in proper location.

2.2 TS4-F INSTALLATION
Smart modules with an integrated TS4 Junction box are installed
and connected in series just like standard PV modules.
Connect modules with TS4-F in series before powering on the RSS
Transmitter.

2.3 TS4-R-F INSTALLATION
Connect the long output cables
of the TS4-R-F units in series to
form strings, as you would with
standard PV modules

Standard modules can be equipped with TS4-R-F add-on/retrofit
units as shown above.
Always connect modules to TS4-R inputs before connecting outputs.
Each TS4-R-F must have a PV module connected to its input before connecting the
outputs of TS4-R-F units in series.
To disconnect TS4-R-F from a module, disconnect the TS4-R-F outputs from the string
before disconnecting the TS4-R-F inputs from the module junction box.
