Tips: Buy 50kW three phase grid tie solar inverter for solar system

Buy 50kW on grid inverter for your solar system will reduces your electricity bill, as you no longer depend on the electric utility alone. And for some months, you will not even pay the electricity bill. Your premises will consume most or all their electricity requirements from the solar system, and you installed this grid tie inverter, sometimes your grid tied solar system will produce an excess power which your loads may not need, so it pushed back to electric utility. By installing 2 energy meters, one of them to measure the energy your premise consumes and the other to measure the energy pushed in electric utility, you will know how many kilo watts hour electricity your system generate and how many kilo watts hour electricity pushed back to the electric utility, and this called Net metering. So, at the end your solar PV grid tie system will return back its price in a certain number of years and you will continue getting your energy saving longer after. An economical feasible study usually done by the grid tie solar system specialists to indicate the return back of investment.
