Product Application
Net and bi-directional metering offers a number of benefits to consumers, and is also good for the environment. By transmitting the excess power to the grid, energy wastage is prevented. The grid, similarly, receives power from a green, renewable energy source, apart from receiving energy from conventional power sources like thermal power plants. Besides, the consumer can save thousands of rupees on energy bills every year. Thus, net and bi-directional metering is a very good money saving choice, and it prompts people to switch to a solar PV system. It can result in an increase in the return on investment on a solar system. With EM118090 is such a PV meter, which can measure the forward energy and reverse energy, that is you can easily know the on-gird energy and off-energy via one meter. In the past time you may need dual metering= 2 meters in your house, one for forward energy, one for reverse energy, but now bi-directional metering or net metering can be your first choice.
