Commissioning a TS4 System - Getting Started

This article documents the Getting Started step of commissioning a Tigo TS4 system. 

'Getting Started':

• Introduction
• Gather the Materials
• Prepare Paper Map
• Install Tigo EI App

1. Introduction

A Tigo TS4 Flex MLPE system is a data-enhanced solar Monitoring, Optimization and Rapid Shut Down (RSD) Safety solution. The system is comprised of 3 components: 

	Cloud Connect Advanced(CCA) Advanced system management and data logging solution. The CCA collects the system data and reports to the Tigo Cloud. It provides service updates and deploys the RSD safety response.
	Tigo Access Point(TAP) The TAP is a rooftop radio transceiver that communicates with the TS4 units and sends data to the CCA via hardwire (RS-485) connection.
	Tigo TS4 Unit(MLPE)  This TS4 attaches to the frame of each solar module and is wired-connected to the j-box of the solar module. Depending on the model, the TS4 units can provide Optimization, Module-Level Monitoring, and Rapid Shutdown (RSD).      Models:  TS4-A-O- Optimization + Monitoring + RSD TS4-A-S- Monitoring + RSD TS4-A-M- Monitoring TS4-X-O-  Optimization + Monitoring + RSD TS4-X-S-  Monitoring + RSD

2. Gather Materials

Gather the Tigo portion of the system (CCA, TAP, and TS4s) and other items not included in the Tigo system purchase. 

3. Create Paper Map

Site configuration requires entering bar codes for the Cloud Connect Advanced (CCA) and each of the TS4 units (MLPEs).  

The Tigo TS4 units have two barcode stickers (one permanent and one that can be removed). The one on the right is intended to be removed and placed on your paper system map.

A system map can help to confirm serial number locations. This step can be done after the physical installation (all modules and TS4s are in their final position). Make the paper map big enough to accommodate all bar code stickers without overlapping. You'll be placing the serials in their correct locations.

Tip: To reduce typos, you can also use a barcode scanner to enter the serials into the EI Portal.  Any USB barcode scanner should work. They are an inexpensive solution and simple to operate.

If you are configuring a large system, it helps to make a spreadsheet showing string assignments for each inverter, CCA and TAP.  For example, download:  String_CCA_mapping.xlsx

4. Install Tigo EI App

Download and install the Tigo Energy Intelligence (EI) App. For full instructions on how to install the Tigo EI App, see Install Tigo Energy Intelligence (EI) App.

This completes the Getting Started step of the commissioning process.

Next Steps

Continue to create and edit a system. Choose either method (EI App or EI Portal).

• Create and Edit a System - Using EI App 
• Create and Edit a System - Using EI Portal 

Tip: Use EI Portal method, online (via the Tigo EI Website) to pre-commission large systems.
