Spanish inverter manufacturerIngeteamhas expanded its utility-scale product portfolio with the Ingecon Sun 300TL, a high-density string inverter designed for large photovoltaic plants requiring high power density, industrial-grade communications and compliance with European grid and safety standards. The unit measures 1,045 mm x 1,045 mm x 400 mm and weighs 115 kg. It is designed to operate in ambient temperatures ranging from -30 C to 60 C and is certified for installations up to 4,000 metres above sea level. Featuring up to 300 kW output power through a single maximum power point tracking (MPPT), the inverter has been designed to reduce the total number of inverters required for utility-scale PV plant configurations. Ingeteam said the higher power density can contribute to lower balance-of-system costs and simplified installation layouts. The new product supports a maximum DC voltage of 1,500 V and offers a wide MPP operating range of up to 1,300 V, enabling increased design flexibility for different module configurations and plant topologies. DC terminal connections support cable sections of up to 400 mm2 or 2 x 240 mm2 per pole. According to the company, the inverter reaches a maximum efficiency of 99.05% and a European efficiency rating of 98.60%. It also features DC harnessing cable compatibility, which the company says can help reduce overall cabling and labour costs during project construction while improving overall project cost-effectiveness. A central focus of the new platform is its integrated industrial communication architecture. The inverter includes standard Wi-Fi connectivity and Single Pair Ethernet (SPE), allowing communication distances of up to 1,000 metres while supporting daisy-chain connections between multiple inverters on the same communication line. The IP66-rated inverter has additionally been optimized for stacked mounting arrangements within string stations, enabling a virtual central power station configuration that reduces station footprint while simplifying installation and cabling connections, according to the manufacturer. Integrated components include AC quick connectors, Type II AC and DC surge arresters and Wi-Fi communication. Protection functions include output short-circuit and overload protection, anti-islanding with automatic disconnection, insulation fault monitoring, AC and DC overvoltage protection through integrated Type II surge arresters and an integrated DC relay. The platform includes low-voltage ride-through capability, reactive power delivery, reactive power injection during night-time operation and active power control functions for grid support applications. Additional features include PID recovery functionality, high-temperature performance and simplified maintenance access. This content is protected by copyright and may not be reused.
