Tigo revamps wireless communication approach in TS4 lineup with new device, architecture

Tigo Mesh

The software that allows each TS4 unit to act as a relay station for signals, Mesh extends the wireless range of communication up to 230ft (70m).

I admit it: I can’t keep up with all of the Tigo news these days. Here’s the latest two announcements (not including this partnership with Solectria), which complement one another: The new Tigo Access Point (TAP) and Mesh communication architecture.

TAP wireless communication

TAP is a new wireless device for communication between the Cloud Connect Advanced (CCA) universal data logger and the TS4 units. With TAP, Tigo wants to improve the data management of residential, commercial, and industrial solar systems by wirelessly communicating with smart modules.

Each TAP collects data from up to 300 TS4 units (~100 kW systems) or up to 600 modules using TS4-R-X-Duo (~160 kW systems). It also greatly improves safety with module-level deactivation for Rapid Shutdown. When paired with a CCA, the TAP provides unparalleled visibility into solar installations. Similar to the Tigo’s legacy Gateway product, the TAP is small in size with a wider range and increased module capacity.

“The new TAP was developed in response to the growing demand for reliable Rapid Shutdown solutions,” says Zvi Alon, Chairman & CEO at Tigo. “Our main goals were to improve visibility, simplify installation and ensure safety in a communication device that can now individually collect data from hundreds of smart modules. Tigo’s commercial and industrial project partners with large PV systems especially benefit from this cost-competitive solution in time for NEC 2017 to take effect.”

The Tigo system has three components. First, the TAP which wirelessly communicates with the smart modules and is hardwired to the CCA via an RS485 cable. Second, the smart PV modules that are equipped with integrated (TS4-X), retrofitted/add-on (TS4-R-X), or retrofitted/add-on for 2 modules (TS4-R-X-Duo). Third, the CCA which collects data from all PV system components – including modules, inverters, revenue-grade meter, etc. – and sends system information to the cloud.

Mesh

Mesh is a new communication architecture to simplify the solar design process and accelerate commissioning steps. With Mesh and TAP, customers eliminate the need to address any roof obstruction or orientation constraint. The software that allows each TS4 unit to act as a relay station for signals, Mesh extends the wireless range of communication up to 230ft (70m). Mesh also allows data collection from up to 300 TS4 units (~100kW systems) using a single TAP or from up to 900 TS4 units (~300kW systems) using a single CCA. Most importantly, Mesh supports multiple communication paths between TS4 units to minimize packet loss, improve data integrity, and increase reliability at high speed.

“Mesh is the groundbreaking communication technology that makes Tigo’s TS4 Platform and communication accessories the most flexible, cost-effective, and robust solution for solar arrays around the world,” says Maxym Makhota, VP of Software Development at Tigo. “We are thrilled to roll out this software simultaneously with the new TAP so our customers can build and maintain efficient systems with as few costs as necessary.”

Mesh must be paired with Tigo’s CCA, TAP (or legacy Gateway), and UHD-Core TS4 units – integrated (TS4), retrofitted/add-on (TS4-R), or retrofitted for 2 modules (TS4-R-Duo).

Alternative Resource Group wants to install more clean energy in developing regions via blockchain

alternative resource group

Alternative Resource Group (ARG), a U.S.-based energy project development company, is out to level the playing field by providing companies with more control over the power they need. By tokenizing large energy infrastructure projects, ARG will bring clean energy to regions in the world that historically have had challenges in getting competitive rates for traditional finance to fund these types of projects. ARG constructs privately owned decentralized power plants in geographic areas that would otherwise be decades away from access to traditional power grids or sufficient supply.

“Investors attracted to ARG see the company as a paradigm changer that offers a simple but powerful premise – ‘Power anywhere in the world. Anytime’,” says Michael Lumbley, Project Development Director for ARG. “A major shift is underway in the way companies around the world find the electricity they need to operate. The change could lead to an increase in manufacturing companies in new areas around the world, creating lower-priced consumer goods. Even better – it provides cleaner power.”

Energy is one of the biggest issues industrial and manufacturing companies face each year. Regions with strong, stable power grids have a huge advantage in attracting industry and economic development.

Combining innovative systems, ARG’s modern power plants provide low-cost, cleaner renewable technology, including solar and wind. The coordinated system is backed up by both natural gas co-generation and advanced battery storage to guarantee power whenever it is needed.
ARG is also developing a new kind of operating platform that manages a secure smart-grid system using an Internet-based advanced blockchain backbone and digital ledger technology. The company is building modular micro refineries that process waste gas from oil exploration and convert it into a useable fuel, including jet fuel, gas, diesel and LP. These ultra-low emission refineries help ARG attain its goal of reducing emissions in energy production by 50%.

What does all of this mean to international economies?

“With the global need for energy predicted to double by 2035, it means the whole world is now open, with opportunities for new areas in the U.S. and smaller countries to enter the power production game,” says Lumbley. “This advance in energy infrastructure not only drives development in impoverished areas, it brings cleaner, renewable energy to the planet.”

Along the border in Mexico, for example, power grid operation is unreliable. Market reform has sparked new investment from other countries, and approved companies continue to move forward under Mexican President-elect Andrés Manuel López Obrador. But inconsistent power supply is severely hampering progress. High-tech manufacturers in the region experience brownouts and hard stops on million-dollar pieces of equipment that shut down, limiting operations.

ARG’s new system of energy production now offers a reliable way to stabilize the power grid for everyone in the region. The system is attracting attention from major industries, including maquiladora companies that partner with giant manufacturers from the U.S.
Eventually, this advanced way of thinking about electricity delivery could provide new energy resources to our increasingly power-hungry world. For now, ARG is providing investors with a new way to support change as a path to profit.
