SAVE THESE INSTRUCTIONS
•This manual contains important instructions for installation and maintenance of the Tigo Energy®
product models TS4-L, TS4-O, TS4-S, TS4-M, TS4-R-O, TS4-R-S, TS4-R-M, TS4-R-O-Duo, TS4-R-S-Duo, TS4-R-
M-Duo, ES-GTWY-020, Tigo Access Point (TAP), Cloud Connect Advanced (CCA), and related Tigo
Energy software and mobile applications.
•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 Tigo Energy Module Maximizer 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.

1.1 TS4 FLEX MLPE FUNCTIONS
The TS4 versions are the bases on top of which functional
covers are installed. These covers contain the module-
level electronics and determine its functionality.
TS4-O: OPTIMIZATION: In addition to safety, monitoring, and PV2.0
synchronization, TS4-O optimizes each PV module when its
performance is affected by shade or mismatch
TS4-S: SAFETY: The TS4-S provides the necessary safety and monitoring
services to satisfy NEC 690.12 Rapid Shutdown requirements for 2014
and 2017
TS4-L: LONG STRINGS: The TS4-L is the complete Smart Module solution.
It is ideal for systems requiring fully optimized performance at the
module level, monitoring, safety, and longer strings click here to see
the TS4-L string sizing info

TS4-M: MONITORING: The TS4-M provides continuous system-wide
monitoring to make customer support and fleet workflow on track

3.2 CCA & TAP WIRING
- + B A
Connect multiple TAP units in series and leave terminating resistor only in final
TAP.
If using the quick connectors, remove the terminal block from the TAP and
strip approximately 3cm of insulation from the end of the cable.
Use a small flathead screwdriver to press the conductors into the quick
connectors. The individual conductors do not require stripped ends.
