Tigo logo

Tigo’s adding a few more options to its UHD-Core optimizers lineup announced last March. Joining the TS4-L (Long Strings) and TS4-O (Optimization) will be TS4-M (Monitoring) and TS4-S (Safety). The UHD-Core TS4-M is a cost-efficient MLPE monitoring device that produces a high sampling rate. The TS4-S adds to TS4-M’s functionality by providing module-level deactivation capabilities. The company says this release completes its TS4 platform featuring an enhanced design architecture and component rating.

TS4 optimizers explained

Tigo TS4 optimizers with UHD-Core technology support more module types than any other optimizer on the market for three reasons. First, the maximum input voltage at standard testing conditions has improved to 90V which allows for compatibility of modules with up to 96 cells. Second, the maximum input current has increased to 12A which enables the use of the highest efficiency and bifacial modules on the market. Third, the power capacity has upgraded to 475W to support the world’s most powerful modules. These enhanced electrical characteristics of the UHD-Core technology result in higher energy harvest for any module up to 475W.

“The demand for our innovative UHD-Core technology in the TS4-L and TS4-O optimizers was so impressive that we have expanded the offering to include TS4-M and TS4-S,” said Zvi Alon, CEO of Tigo. “Our commercial and utility customers will be pleased with lower O&M costs, safer solutions, and expanded inventory. Now that our TS4 platform has the highest accuracy in remote module-level monitoring, we plan to bring more superior communication solutions to the market in the near future.”

A New Connection: How the cell-optimizer, string inverter combo could change PV systems

This TS4 UHD-Core platform is fully monitored through Tigo’s Cloud Connect Advanced (CCA) data loggers with remotely upgradeable firmware. The high definition sampling rate technology also allows the highest accuracy remote monitoring of voltage and current available in the market – including remote access to individual module information (i.e. panel type, barcode, manufacturing origin, location, and production date). All Tigo TS4 platform products are autonomous and feature selective deployment. They can be fitted to new or existing installations on any string or sub-string size, driving the optimization cost as low as 2 cents per watt. They are compatible with most of Tigo’s inverter partners and any module type including monocrystalline, polycrystalline, thin-film, and bifacial.

SIC USA looks to retrofit PV plants using Satcon inverters with power optimizers

SIC USA LLC and Alencon Systems LLC announced a partnership for promoting improved performance at existing PV plants with Satcon solar inverters. SIC USA is the exclusive US importer of the Satcon line of PV inverters. Alencon Systems is the manufacturer of the SPOT – String Power Optimizer and Transmitter – family of utility-scale PV DC-DC optimizers.

What the partnership does

satcon_alencon

As part of this partnership, SIC and Alencon’s engineering teams will work closely to ensure the interoperability of Alencon’s SPOTs with existing Satcon’s inverters already installed in the field. In addition to working in close partnership, Alencon has installed a grid-tied Satcon inverter in its power electronics lab in Hatboro, Pa., to provide real world test conditions for the performance of its SPOT PV DC-DC optimizers with the Satcon inverter platform.

Pairing Alencon’s SPOTs with Satcon inverters already installed in the field provides PV plant owners with a number of benefits. Alencon’s SPOTs increase energy in existing PV plants by providing string level maximum power point tracking (MPPT) to plants equipped with central inverters. Each Alencon SPOT has four MPPT inputs and thus can reverse the effects PV panel yield mismatch caused by uneven module degradation or other factors. For PV plants between five to ten years of age, Alencon’s SPOT will typically increase DC energy yield between 5 – 10% by mitigating the negative effects of mismatch while performing a host of other energy yield optimization functions.

Additionally, by injecting galvanic isolation between the PV strings and the Satcon inverter, Alencon’s SPOT can extend the life of the inverter by protecting it from any harmful faults that occur in the PV array. By isolating every string, the Alencon SPOT will also reduce the on-going operations and maintenance costs of plants with Satcon inverters by isolating each string in the event of trouble.

The latest version of the SPOT features a more rugged, low profile design along with a number of unique power electronics features to allow both new and existing PV plants to generate more energy while also streamlining their operations and maintenance (O&M) activities. Alencon’s SPOT can improve the yield of PV plants from anywhere 5 – 10% on average.

Galvanic Isolation: Alencon’s Unique Solution for Better PV Plant Performance

Alencon’s SPOT provides complete galvanic isolation between PV strings and the inverter. This unique feature makes the SPOT an incredible tool for O&M because any arc or ground faults that occur with a PV string can be isolated from the rest of the solar system. Additionally, arc and ground faults can be quickly traced to the exact PV string where they are occurring which means maintenance can be more efficiently deployed and repairs can be safely done on one string while the rest of the PV plant continues to produce power.

Voltage Step-Up: Lower Conduction Losses, Better Inverter Performance

Alencon’s SPOT allows for a broad range of both input and output voltages, so it can be deployed to improve the performance of any PV plant, irrespective of its age. By stepping up voltage on the output, the SPOT is able to markedly reduce conduction losses. Additionally, by feeding a central inverter fixed voltage, the SPOT will allow a central inverter to run much more efficiently by providing it the level of voltage that allows it to perform at its highest rated efficiency.

The PV-IoT for Performance Monitoring and Control

In addition to providing a number of energy production enhancing features such as granular MPPT, galvanic isolation and voltage step up, the SPOT is also a very unique PV plant performance monitoring tool. The SPOT offers continuous, wireless communication to a central aggregator, so the performance of a PV plant can be studied down to the string level. The SPOT is an Internet-of-Things (IoT) ready device. By applying the PV-IoT, the Photovoltaic Internet of Things, the SPOT allows PV plant owners to assure their assets are operating at peak performance.
