Photovoltaic Solar Power Plant Info Terminal IT-1 is a multiprocessor device designed for monitoring, managing, registering and visualizing the solar power station. IT-1 is a communication and visual center of a solar power plant. According to the solar power plant, communication link is established or digital and analog inputs / outputs are connected to some subsystems e.g. with photovoltaic collectors via ISK-xx Intelligent Connection Boxes, with inverters via inverter controllers, with meteorological and process sensors via Weather Monitors (MM-100), with the power grid (power plant connection) via the DT-10SE Remote Terminal. The graphic LCD display dynamically displays the status of each subsystem as well as the entire power plant. As a multifunctional device, it also enables local and remote visualization and system status registrations.

A range of communication links is available for communication with the control center, e.g. GSM / GPRS, Radio modem, RS485, FO, Ethernet, Web portal etc. According to the available communication paths, remote control with the power plant is realized through the DT-100SE Remote Terminal which also contains an uninterruptible power source.
