In the wake of a linesman losing his life in Bicholim on Friday, the Goa government has reportedly decided to bring a ban on use of inverters in the state which produce a reverse current. It is learnt that the electricity department will issue notification as regards specifications of inverter installations. The common reason for reverse voltage is when power is disconnected from a system. Off grid and hybrid inverters do run backwards in that they can take AC in and output DC to charge a battery bank. The most common cause of reverse current is having a higher voltage on the output than on the input, inducing current to travel through the system in the opposite direction from what is intended. When the inverter is in operation, it generates an AC output that may flow in the opposite direction of the incoming AC supply, resulting in a reverse current in the supply main lead. Reverse polarity can increase the risk of electrical shock. Necessary permission from the electricity department should be made mandatory while installing inverters for private use.
