Wear and USE appropriate PPE for the application. Suggestions: gloves, sunscreen,….
!
Wear and USE appropriate PPE for the application. Live voltages may be present.
1.
Each PV string will produce less than 30VDC until the RSS Transmitter is activated/powered.
2.
When power is provided to the RSS Transmitter the PV strings will produce full voltage under the
environmental conditions.
3.
Commission the PV system as per best practice.
3.1 Pre-commissioning checklist
3.2 Commissioning notes
Issue
Check
No string voltage
Check that all string connectors are securely connected.
Lower voltage than
expected
Check that all PV module connectors are securely connected.
Note
– with no keep-alive signal the string voltage will less than 30VDC.
Check that the RSS transmitter is powered on. If multiple transmitters are used, check that all
are of the Pure Signal Technology (PST) series and are properly wired.
Inconsistent
voltage reading
when no signal is
present
1.
Apply power to the RSS Transmitter
2.
Use an RSS Signal Detector to determine if the individual TS4s are receiving the keep
alive signal. If so, check the string is less than 300m.

Acceptance Criteria
TS4 installation
All PV modules are connected to a TS4-A-F/TS4-A-2F.
Tigo RSS
Transmitter/PST
The Tigo RSS Transmitter is installed per the RSS Transmitter Installation Manual. If
inverter integrated, follow the inverter manufacturer’s instructions for signal/power.
Voltage check
The TS4-A-2F passes 0.6VDC at the output to the string.
String voltage = 0.6VDC x # TS4s in the system.
If TS4-A-F are also used in the same string, add 0.6V for each additional TS4-A-F.
Connections
All connectors are securely mated and of same type.
Wire Management
All conductors are properly secured throughout the array. ANSI/NFPA 70 wiring methods
used. Multi transmitter systems have PST transmitters installed and properly wired. Refer
to RSS Transmitter Installation manual for details.
Workmanship
Wire management and general best practices were used.
