Off The Grid-On The Grid-Grid Tied

bulb.jpgOn-Grid energy storage allows producers of electric energy to send their excess electricity to the transmission grid, or to a temporary electricity storage site which can be used as a producer of energy if the demand ever becomes great.  This is a stellar method of storing off-peak power which can be used during peak electricity usage times.  This can also make it unnecessary for photovoltaic or wind turbine users to keep battery storage, because connecting themselves to the grid makes what is essentially a giant battery available to them.  Grid energy storage is generally very closely related to the concept of distributed generation, which only functions correctly when arrangements like vehicle-to-grid systems and net metering are put into place.  Additionally, regulatory support is often needed.

Off-grid renewable energy sources and systems tend to offer users a greater amount of support.  Off-grid systems offer renewable energy which is captured by solar panels, water turbine systems and wind which is friendly to the environment as it serves as an energy source which is completely free of pollution.  Off-grid systems also provide complete freedom from utility bills, as well as freedom from a power supply which can be interrupted.  Why allow yourself to be connected to an energy line when instead, you can store and utilize energy that you created all on your own?  Off-grid renewable energy systems utilize energy that is gathered from the wind, the sun and the water.  Numerous sources of renewable energy are needed in order to provide the power that you need, and an energy storage site is required so that energy can be used even when the river is calm, the wind is not blowing or when the sun has set for the evening.

Grid-tied electrical systems, which are also called ‘tied to grid’ or ‘grid tie’ systems, are grid energy storage systems which feed excess capacities back to the local main electric grid.  This means that when insufficient amounts of energy are being generated, or when batteries are not fully charged, the electricity can be drawn from this mains grid in order to make up for the short fall.  If a battery is being used to store electricity, the system is typically called battery-to-grid or B2G, or vehicle-to-grid or V2G.  Essentially DC or Direct Current electricity is passed to a grid-tied inverter which creates the alternating current and generates phrase-matched electricity.
