THEIA TL String

SOLAR INVERTERS: 4.3kW – 7.2kW

High Performance, Transformerless String Inverters

With efficiencies up to 98%, and very low power feed levels, the THEIA TL String inverter range maximizes both the energy harvested per hour and the number of working hours per day on an installation, to provide reliable and steady power for longer.

PRODUCT DESCRIPTION

Performance

With power feed levels of <8W the THEIA TL String inverter range starts working earlier in the morning, while other inverters are still sleeping, until later at night to harvest energy from even very low irradiation levels. The extraordinary wide DC input voltage range and high overload capacity enables multiple plant configurations across many PV module types, and with all inverter models having multiple PV string inputs as standard, and the option of an integrated DC disconnect switch for isolation, flexibility of plant design is ensured.

Reliability

Using state of the art components and DIVE, a patented technology, to increase efficiency, especially at the lower input power levels, the THEIA TL String inverter range achieves outstandingly high efficiency levels across the broadest operating range. High efficiency alone, however, is not sufficient to maximize the energy yield that can be obtained. The decisive measure is how many Wh an inverter can gain from a PV generator, and in this the THEIA TL

String range also excels by using Rapid Adaption Control Maximum

Power Point tracking (RAC-MPP), a principle for extraordinary high yields, even under extremely fluctuating and dynamic irradiation conditions. The result is quick, efficient, and top class MPP tracking. With a protection level of IP66 and smart thermal design, the inverter range has the ability to withstand environmental extremes and still operate when other devices have failed.

Ease of use

Using simple connection systems for both the AC and DC terminations, country settings adjustable on site without additional tools, and the ability to automatically transfer settings from one inverter to all the others thanks to master programming across the connected THEIA TL String inverter network, an extra quick installation is possible.

Monitoring

With a large, backlit, full graphical LCD, performance and important operating conditions are displayed in clearly arranged graphs and diagrams, including week and year review functions, to allow a quick on-site performance check at any time. Even after sunset, you can communicate with the THEIA TL String inverter to access the current measured data and plant performance, and monitor unexpected plant behaviour day and night.

Datalogger

Throughout its operating life of more than 30 years, the inverter’s built-in datalogger saves your measured values, yield and performance data. The datalogger is the only one on the market that functions with the high precision of an electricity meter, with events recorded in a separate protocol memory.

Communication

With a variety of different THEIA String communication devices available, the inverters can be integrated into total plant monitoring systems. The EIA485 interface connects the THEIA TL String inverters and gives them access to the world of THEIA TL String plant monitoring. This high-performance interface allows cable lengths of up to 1,000 m.
