The new inverter has been presented at the Solar-Tec fair in Cairo (Egypt) in December 2016. This new three-phase inverter, commercialised under the name Ingecon Sun 100TL, is suitable for indoor and outdoor installation alike, and is primarily directed at commercial, industrial and large-scale projects.
Its main advantage over other models on the market lies in its significant cost savings potential, given the fact that its high power density means that it is possible to drastically reduce the number of inverters to be installed and, therefore, the total amount of cabling. Furthermore, no combiner boxes are required (in DC or AC) and neither is a neutral cable necessary, thereby reducing the total AC cabling cost by up to 20 percent. All this leads to huge reductions in capital expenditures (CAPEX).
This inverter also means lower operating costs, thanks to the wireless communication which permits the startup, monitoring and control of the PV system through a mobile phone, tablet or laptop. Furthermore, its string inverter philosophy guarantees minimum possible maintenance requirements, with no need to vacuum the inverter interior or to check the state of the fuses, the thermal magnetic breaker or torque.
In addition to its high power density, the inverter's main features include its high maximum efficiency (98.8 percent), Wi-Fi and Ethernet communications supplied as standard, maximum DC input voltage of up to 1,100 volts DC and advanced grid support functionalities, with a low-voltage ride-through capability and reactive power capability. What's more, this inverter family is also suitable for three-phase self-consumption systems, with or without the injection of excess energy into the public grid.
