We are all of us these days encouraged to save cash, save energy, and save the planet.

Here the energy is produced by a solar panel, but it could in the same way be a wind turbine or generator, but it does require to be 14 to 50 volts.
The solar panel voltage now has to be raised to home voltage in order to save cash.

simply plugging into a wall socket is all that is needed to connect the grid tie inverter to the mains. The inverter electronics regulate the secure connection to the mains.
So the simple combination of, solar panel and grid tie inverter will furnish the house with power, which you would have to buy from a company, for all the time the sun was shining.
Always to be born in mind is safety the electronics in the grid tie inverter will only let current to feed when the house power is on. This removes any danger of power being fed back up the power lines. But if the power fails the grid tie disconnects.
The grid ties can be added, together with other solar panels to increase the power. Any extra power not needed by the home will cause the meter to run in reverse this will make a saving in the bills due.
And if you need power at night a wind turbine can be used?
These machines are not costly and the manner they are joined to the home is not expensive, making the whole scheme economic. The alternate is to use batteries and a conventional power inverter to make electricity for the home, this has the benefit of night time power, but the extra cost and space needed for the batteries, makes this awkward in comparability.
I think the grid tie is the most cost efficient way to save cash and supply electricity in the household, it may not be a means to substitute the power company, but it will save money.
I Know many of you are anxious to save cash, energy and do your bit to save the planet. But Solar Panels and batteries, the size and cost with ALL those batteries Well NOW YOU DON'T have to because the GRID TIE Inverter, it's simple and easy - It just plugs in.
