Performance
Using the latest of Eltek Valere’s unique, high frequency conversion technology, the THEIA HE-t combines galvanic isolation with unprecedented levels of performance. With its extreme efficiency and global design solutions, it defines a new standard when it comes to performance, flexibility and user friendliness, as well as offering superior reliability under all conditions. Allowing the user the ability to ground the positive or the negative terminal on the DC side makes the device suitable for use with either monocrystalline, polycrystalline or thin-film PV modules of any technology, whilst maintaining the highest international safety standards. With early start-up and high efficiency at low irradiation, longer operation time and maximum energy harvest is ensured.
Reliability
The efficiency of the THEIA HE-t inverter range is one of the highest amongst inverters of all types, and coupled with bespoke Maximum Power Point Tracking, extraordinary high yields, even under extremely fluctuating and dynamic irradiation conditions, are achieved. With a protection level of IP65 and intelligent thermal design, the inverters are able to withstand temperature variations, high humidity and dust levels, and are able to operate with convection cooling only, giving the user confidence that the PV plant will operate consistently over the lifetime of the installation.
Ease of Use
Flexible connection kits make it easy and cost effective to configure for various conditions and country-specific requirements, while multiple PV string inputs as standard provide for easy installation and maintenance. With all connections in an easily accessible front compartment, a multilanguage display, and simple country configuration setup, installation occurs in the minimum amount of time. Even in installations containing dozens of inverters, setup is minimised by the use of an automatic transfer of settings from one inverter to the others thanks to master programming across the connected THEIA HE-t inverter network.
Monitoring and Communication
Introducing a new level of user friendliness, the THEIA HE-t range has an integrated web server, thus eliminating the need for any external web server. A color screen with touch sense buttons provides an intuitive user interface, while displaying operating conditions in clearly arranged graphs and diagrams. For sites with multiple string inverters installed, a single inverter can act as a central monitoring hub, collecting data from all inverters linked on the site network to provide a single point of access, allowing a quick site performance check – either remotely or on-site – at any time.
