FOTO CONTROL 3f 400
FOTO CONTROL is no longer being developed. Check out the latest generation of our NEXICONTROL three-phase inverters.
Characteristics and advantages
High efficiency
An efficiency of 96.5% is achieved thanks to advanced 5th generation IGBT switching elements, minimized self-consumption and the use of low-loss magnetic circuits made of amorphous metals and ferrite-powder materials.
Parallel cooperation of inverters
The automatic cascade mode allows inverters to work in parallel, increasing the achieved yield by 1.5 to 2%.
Controlled 4-quadrant rectifier
The use of a controlled rectifier ensures a very low proportion of higher harmonic currents (THDi max. 3%) and full reactive control with cos φ adjustable from 0.00 to 1.00.
Automatic phasing into the network
The device can instantly adapt to the frequency and voltage of the grid, ensuring smooth operation.
100% output symmetry
Output power and voltage are fully symmetrical, without the need for a “power balancer” unit.
Decentralised solution
Optimal ratios between the number of inverters, the availability of the PV plant and the price ensure the efficiency of the system.
Integrated protective elements
PV COMP includes DC fusing, leakage current protection, insulation condition measurement, and a built-in AC disconnect switch for quick disconnection in the event of voltage loss or unauthorized mains conditions.
Flexibility of string wiring
The possibility to connect the strings in distribution boxes with DC outlet increases the variability of solutions.
Quick disconnect
The compact unit can disconnect the output contactor within 10 ms in the event of phase voltage loss or unauthorized mains conditions.
Simple parallel shifting
Inverters can be easily shifted in parallel to increase power output as required.
Performance monitoring
Indication of power in kW and kWh produced allows tracking of production for the selected time period.
Meets quality and safety requirements
The FOTO CONTROL 3f 400 meets voltage and current quality, safety and EMC standards.
Long service life and reliability
The equipment is designed with reliability and efficiency in mind, with the use of foil capacitors and high quality fans extending its lifetime, which exceeds the payback period by several times.
Extendable warranty
The standard 2-year warranty can be extended upon request.
Advanced communication options
Support for RS-485 control, with the option of Profibus DP or Modbus RTU communication, enables easy integration into higher-level systems.
Additional equipment
Telemetry
Allows remote access to the plant control system for monitoring and management.
Web visualization
It provides secure internet access via Ethernet, Wi-Fi or 4G network.
Automatic notifications
The system supports sending alarm reports and summary reports via e-mail, SMS or FTP.
Removable graphic display
The handy detachable graphic display allows easy operation and clear display of key information about the device.
