Why India needs Grid Interactive Inverters ?

Solar-Off-Grid

Solar Off-Grid System

Solar Market is broadly categorized into three segments globally

  1. Solar Off-Grid :Off Grid Inverters are principally meant to be used with solar power systems (or wind and hydro) for a home or business totally disconnected from the electric utility company. They can also be used for providing emergency backup power when the electric company’s power fails.
  2. Solar Tie:A grid-tie inverter is a power inverter that converts direct current (DC) electricity into alternating current (AC) with an ability to synchronize to interface with a utility line and provides net metering capability. Net metering allows a solar power system owner to sell surplus energy back to the utility, thereby reducing or eliminating your electric bill.

  3. Solar Grid-Feed :Grid-interactive systems are based on their grid-tied and off-grid counterparts. Like the inverter in grid-tied systems, the inverter in a grid-interactive system can convert solar-generated DC power into AC power that is then fed directly to the grid.

    In a grid-interactive system, however, the inverter has multiple additional functions to perform. Under normal conditions, the inverter maintains the battery in a state of full charge in preparation for use during power outages. When the grid goes down, the grid-interactive inverter seamlessly steps in to invert DC power from both the solar and battery sources into usable AC power to run selected loads.
