Solar micro inverter
In December 2013, Vasavi Electronics launched a solar micro inverter called the VE250 for solar applications. The product is designed with innovative concepts to nullify the losses and extract maximum power possible. It has a very high efficiency of up to 96 per cent and extracts 25 per cent more power compared to convectional inverters. This water-proof micro inverter can be fixed behind the solar panel to reduce cable losses and can be easily installed based on the plug-and-play concept. In conventional inverters, if one of the panels is not working, the whole system stops working but with this inverter, the rest of the panels will continue to deliver the power. It ensures a THD of <5 per cent.
In December 2013, Amara Raja Batteries launched two new batteries with ratings of 12V120 Ah and 12V150 Ah in its Quanta series of sealed maintenance free (SMF), valve-regulated lead-acid (VRLA) batteries, which are useful for UPS applications. This range provides OEMs with the flexibility to make optimal use of the batteries’ size. These two new batteries have been launched in Delhi, Mumbai, Kolkata, Chennai, Bengaluru, Hyderabad and Pune. The Quanta series caters to UPS systems manufacturers and customers across segments like banks, IT companies, BPOs, industries, government departments, hospitals and education institutions.
MPPT Solar charge controller
In October 2013, ARVI launched its maximum power point tracking (MPPT) solar charge controller that converts existing online UPS/ offline UPS/inverter to a solar based system. It comes with digital signal processing (DSP) based technology, intelligent MPPT tracking, a long life design using IGBT, high converter efficiency >96 per cent, and a computer interface via RS-232/RJ -45. It offers 35 per cent extra battery life using a temperature compensated float cum boost battery charger, provides deep discharge protection by adjusting the DOD level setting and day time battery discharge protection for night operated load. The product is compliance certified as per IEC 62509:2010 by a NABL certified lab.
