How can we convert the existing home inverters in to a solar inverters?

While there is a considerable interest in the utility scale grid connected solar power plants, roof top systems are  equally getting attention and the country has about 43 MW of roof top systems connected to the grid.  Rooftop PV systems find much more attractive due to the fact that these systems have potential to reduce transmission and distribution losses reduce additional burden of laying the T&D infrastructure. Connecting roof top solar PV systems to the grid is a great challenge, specially the rooftop systems which are in kW capacity, the utilities face tremendous challenge in terms handling the unstable sources of electricity at distributed level. While the PV system cost have come down considerably, roof top systems provide altogether a new market to the urban households who already has an inverter and battery storage systems as back up source in the event of grid unavailability.

Most of Indian households are not having electricity access due to grid unavailability and have to install inverters which charge batteries from the mains and use the same electricity during the periods of non availability of grid. The grid supply is generally not available from 30%-50% of time in the small towns and condition in villages is even worse where the electricity supply is available for a period of only 8hrs in a day. Often the grid supply is not even enough to charge these inverters to provide uninterrupted power supply. These inverters when under the charging mode create additional peak demand which at times makes the load relief measure undertaken by the Utility as irrelevant.  Integrating solar Photovoltaic with these existing home inverter system can provide relief to the households for additional charging option apart from normal grid charging of the storage batteries and will also reduce the system peak which create another set of problems to the utilities. In the event of non requirement of solar electricity at the household, these surplus electricity can be fed back to the grid as well.  Firstgreen along with some of the leading solar inverter manufacturer have developed a special device which can convert your existing home inverter in to a solar which can charge the existing battery through the solar panels as well. The home owner has to install this converter along with the existing inverter which also act as a a battery charge controller and connects the AC mains & load output control system all in one.

  2. A solar power inverter is an important electronic device that converts electrical power generated by solar energy into clean ac power. So to get additional profits, a home inverter system can be converted into solar inverters which can work better.
