New solar grid-tie inverter can be powered by solar and mains
Su-Kam, has launched the solar grid-tie inverter, which can be powered by mains as well as solar energy, working even at voltage as low as 80-450 V (DC) and 150-280 V (AC). It is able to generate solar power even during low periods of sunshine. With an efficiency of almost 100 per cent, the IEC- certified product can withstand dust and heavy rains. The inverter can also be connected to GSM remote monitoring application, through which customers can monitor and record the performance of up to 25 years. The inverter, priced in the range of Rs 52,000 to Rs 86,000, depending upon the capacity, is equipped with an LCD screen which regularly monitors units of electricity being made, input and output voltage and the like.
Kunwer Sachdev, Managing Director, Su-Kam said, “The solar grid-tie inverter is designed to be highly efficient, yielding RoI within a short span of three years. Equipped with state-of-the-art technology, the product is a viable option not only for commercial establishments but also for home- owners if their state has an active net-metering policy and pays a good price to residents for feeding excess solar electricity back to the grid.”
For working of the inverter, solar PV panels are installed on rooftops that generate DC electricity as the sunlight falls on them. This DC electricity goes to the grid-tie inverter where it gets converted into usable AC electricity. Subsequently, it enters the main supply inlet and powers all connected load through solar power. If there is not ample sunshine, the system runs the load through the main power supply.
