InteliSys NTC Hybrid

InteliSys NTC Hybrid is a standalone controller for hybrid applications that combine diesel gen-sets with renewable sources of power. It is suitable for off-grid (microgrids) as well as on-grid installations. It continuously monitors data from all sources of energy including solar, wind, hydro, energy storage and gen-sets.

• Interface to PV inverters via Modbus RTU or TCP*
• Interface to ComAp InteliGen and InteliSys gen-set controllers** via CAN
• Optimised system efficiency by minimising the necessary dynamic spinning reserve while keeping reliability duringthe PV output drops; the InteliSys NTC Hybrid controller calculates and distributes the dynamic spinning reserve to the gen-set controllers
• The Dynamic Spinning Reserve function allows the controller to adjust the output from the gen-sets according to the output of the renewable source. So, if the power output from the renewable source begins to drop, the controller automatically starts the gen-sets to ensure no drop in energy production from the system.
• InteliSys NTC Hybrid communicates over CAN bus with ComAp gen-set controllers which manage outputs from gen-sets of different installed capacity and various manufacturers. Smart power management automatically select the most efficient combination of gen-sets based on their sizes to maximize fuel savings.
• InteliSys NTC Hybrid provides interface to photovoltaic inverters with respect to the gen-sets minimum loading level. If the gen-set output approaches the allowed minimum, the InteliSys NTC Hybrid regulates the inverter output to prevent the engine from running underloaded.
• Extensive flexibility due to built-in PLC to cover complex site control and various operating scenarios
• Synchronisation of gen-sets with the mains and export/import limitation control to fulfill the utilities needs in on-grid application
• AirGate connection and WebSupervisor offer remote monitoring and full control of the whole site
• Data acquisition from all power sources provides detailed statistics about energy yield in selected interval (day, week, month) and gen-set fuel consumption

* the Modbus master ability is achieved via additional
PLC module (Product name: InteliFieldbus Gateway,

used for compatibility and to ensure prevention from
gen-set underloading
