Sri Ragavendra Power Controls

Choolaimedu, Chennai, Tamil Nadu

Off-Grid Solar Inverter range is designed to meet the requirement of Rural and other remote site applications where grid may or may not be available . This Hybrid system can be used with Solar, Mains DG set combination & with only solar

Using vast experience of designing of such power electronic products embedded with technological excellence from Australia , offers state-of-art single phase Hybrid Solar Inverter-Cum- charger system.
It consists of MPPT PWM Solar Charge Controller with Hybrid Inverter. As per the requirement, the same inverter can supply full DC power for charging of battery through 230V AC mains (wherever available). The Inverter can thus both charge the battery or supply the AC to connected Loads through Grid synchronisation. Provision for command to start / stop of DG set also available, in case battery gets discharged beyond certain level.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.

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:
