3-Phase Bi-Directional Solar Inverter

For larger solar panel installations, including Roof-Top, offers Inverters, both in pure exports as well as Hybrid Bi-Directional systems including battery charging .Backed-up by long experience of designing of such products for Indian environmental conditions and with embedded technical support from Australia, 3 Phase Inverter systems are second to none.It consists of High Efficiency MPPT charging system with Active Front End Converter. The DSP based technology and intelligent software helps in automatic selection of various inputs like Solar, Mains, DG and gives un-interrupted 3 phase AC outputs. Keeping in mind the poor grid conditions in India, like, high voltage /fluctuations, the controller adjusts the output frequency so as to maintain balanced outputs irrespective of imbalance on grid side.Inverter can also be configured to Export surplus power to grid and can be configured for only pure-grid- export mode as well.
The control and monitoring options available are:

Inverter can also be configured to export surplus power to grid. The different control & monitoring options available are:
  • Via the front panel LCD display and membrane key-pad. A structured, software menu-driven system is available for monitoring and setting up the inverter.
  • Via a RS-232 / RS-485 and RJ-45 TCP/IP connection. These connections can be utilized to connect a PC to monitor and configured the inverter locally.
  • The inverter can be connected to a SCADA system through the TCP/IP communication port available.
