By using galvanic isolation, THEIA S String inverters meet the highest international safety standards, and with an extremely low power feed level, they provide power for more of the day than many of their competitors, maximising the working time of the installation.
The wide input voltage range is outstanding, and usually allows installation of a single string of panels even for the higher power inverters, simplifying installation and reducing voltage drop in cables.This inverters is suitable for arrays up to 4200W.
The efficiency of the THEIA S String inverter range is one of the highest amongst inverters containing a transformer. High efficiency under stable conditions alone, however, is not sufficient to maximise the energy yield that can be obtained from an array, as conditions can change quickly on partially cloudy days, and inverters need to be able to react quickly. In this the THEIA S String range excels by using Rapid Adaption Control Maximum Power Point tracking (RAC-MPP). This gives 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 IP54 and smart thermal design, the inverter has the ability to withstand quick temperature changes, high humidity and dust levels, and is able to operate when other devices have failed in the midday heat.
All connections use plug connectors, so are accessible without having to open the inverter, allowing very rapid installation.
The S string inverters come with a large, backlit, full graphical LCD display. 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.
Many inverters power down at sunset. Not so with Eltek - even at night after sunset, you can communicate with the THEIA S String inverter to access the current measured data and plant performance, and monitor unexpected plant behaviour day and night.
Throughout its operating life of more than 30 years, the inverters 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.
