Diversified Technologies has introduced a new micro-grid power distribution system for the simple integration of solar power generators by transmitting DC power along a cable which is suitable for up to 1 Megawatt power transfer. The ‘PowerMod’ Micro-Grid Power Distribution System features direct solid-state switching and includes a DC power supply, DC cable and down converter for providing AC or DC power at the load end point. According to the firm, this new power distribution system offers a link cost as low as US$1.00 per watt, depending upon configuration.
Schneider Electric has launched the Square D 1000 VDC disconnect switch, the first enclosed heavy-duty 1000 VDC solar disconnect on the market. The easy-to install switch functions as a local disconnect for a string of Photovoltaic (PV) panels and are designed for an extended life expectancy in harsh environments.
Bentek Solar’s Multiple Disconnect Safety System (MDSS), used for commercial and utility-scale PV power plant projects, has received ETL Listing to UL 1741 and CSA 22.2 certification. Bentek Solar’s MDSS is designed for large PV solar systems (250KW or greater), and is intended for installation next to the inverter. The MDSS provides multiple UL 600VDC load-break disconnects combined into one easy to install safe compact enclosure.
OPEL Solar has introduced a new wireless, utility-scale solar tracker control network developed in conjunction with its partner, FEiNA, in Spain.
Technology used in GE’s wind turbines, is now being applied to large-scale PV systems. Building on a platform of power electronics, monitoring and controls that enhance wind energy grid integration, GE has developed a 600 kW solar inverter, which includes grid-friendly features to deliver performance in large-scale solar installations similar to conventional power plants.
Siemens AG has developed and manufactured inverters for photovoltaic applications since 1987. The latest products of this development are the SINVERT PV inverters, a family of three phase grid-connected inverters in the range of 60kVA up to 1700kVA.
