Profile: Control Techniques Drives Ltd. is a manufacturer of variable speed drives. Grid tie inverters include a range of transformer-less central inverters for PV installations from 145 kWp to 1.76 MWp. Each inverter is constructed using multiple standard 145 kWp or 175 kW modules. The modules are controlled by intelligent inverter management (IIM) system to maximize energy yield by controlling the active and standby status of each inverter module. The system generates energy in lower light conditions. We also offer power conversion and control solutions for photovoltaic energy systems.
