 I want to introduct something about Pv Grid Connected Inverter. PV grid-connected inverter Products PV grid-connected power system includes PV modules , grid-connected inverter, meter and power switchboard. The PV modules convert the solar energy to the DC power Then the grid-connected inverter convert the DC power to the sine wave AC power which has the same frequency and phase with the grid voltage. The AC power feed-in the grid partly and the other power supply the local loads. Main Characteristics: l Using 32bit DSP from TI company as the controller ; l Using the fifth generation IPM from Mitsubishi company as the power components. l PPT (Maximum Power Point Tracking) technology. l Max Efficiency 95%. l Zero power concept at night. l Perfect protect functions include anti-islanding. l Multi selection: Low frequency transformer isolation type, transformer less type , wide DC input range type. l Self consumption at night 0W l Utility mo
Optical fiber, nonconductive, riser (OFNR) is a type of optical fiber cable. As designated by the National Fire Protection Association (NFPA), this name is used for interior fiber-optic cables which contain no electrically conductive components, and which are certified for use in riser applications; they are engineered to prevent the spread of fire from floor to floor in a building. Typically they are tested for compliance with ANSI/UL 1666-1997, Standard Test for Flame Propagation Height of Electrical and Optical-Fiber Cable Installed Vertically in Shafts. NFPA NEC 2005 Art 770.51(B) FPN.
They are distinct from optical plenum cable, and general-purpose optical cable.
