This article introduces the new RSS Transmitter with Pure Signal technology!
 |
The RSS Transmitter with Pure Signal technology is a patented Tigo innovation that allows multiple transmitters to be connected together and act as one harmonious 'keep alive' signal for all MLPEs (TS4-A-Fs/TS4-A-2Fs) on a system.

Frequently Asked Questions (FAQ):
What documentation and training resources are available for the RSS Transmitter with Pure Signal Technology?
Tigo provides a robust platform with several resources for you to learn more about our products:
How do you tell the difference between the two RSS Transmitters?
Although the transmitters share a similar form factor (and use the same transducer Cores), there are some subtle but important differences:
RSS Transmitter with PST

RSS Transmitter (without PST)

What is Pure Signal technology?
Pure Signal technology allows the Tigo RSS Transmitter to act independently, or in coordination with other PST transmitters, to provide one common (or aligned) signal over a large system. This increases the ease of installation and reduces conductor crosstalk concerns.
How do you connect the RSS transmitters with Pure Signal Technology?
Pure Signal technology requires multiple transmitters to be connected using a Leader-Follower method. For more information, see: Quick Start Guide: RSS Transmitter with Pure Signal technology
Can I replace an existing RSS Transmitter with the new Pure Signal model?
Yes. Also, see the question on mixing RSS and Pure Signal Transmitters below.
When do you use the RSS Transmitter, versus the new RSS Transmitter with Pure Signal Technology?
If the project requires only a single inverter (typically residential), then Tigo recommends the RSS Transmitter (without PST).
If the project is a commercial application, it may have multiple inverters. For these, Tigo recommends the RSS Transmitters with Pure Signal Technology (PST).
Can you mix the RSS and Pure Signal Transmitters within one system?
The mixing of transmitters (with and without PST) within a system is not advised, as it involves secondary signal management. However, if you are working on a system that has mixed RSS transmitters, it is important to:
- Wire all transmitters that have RSS Transmitters PST using the Leader-Follower method. Refer to step 2.2 of the Quick Start Guide: RSS Transmitter with Pure Signal technology.
- Follow the 'PV Conductor Installation – Multi Transmitter Systems – Required Practices' for all conductors that include either a non-PST RSS Transmitter or a mix of PST and non-PST RSS Transmitters. These required practices are in the Installation Manual - TS4-F, TS4-A-F, TS4-A-2F (Fire Safety), RSS Transmitter.
Also, see Crosstalk and How to Mitigate it, to avoid potential issues in your design.
How do you know which RSS Transmitter is in a Tigo Enhanced inverter?
At this time, Tigo Enhanced Inverters only offer the RSS Transmitter (without PST).
Can you order a Tigo EI Residential Solutions Inverter with the RSS PST Transmitter?
All of the Tigo EI Residential Solutions Inverters have the RSS Transmitter (without PST).
