High Efficiency Inverter
From MoxyWiki
[edit] General Description
Inverters are used to convert the DC power output from generation devices such as solar panels into a form that can be used by household appliances and returned to the grid. They convert the power to AC, raise the voltage to grid voltages (240 Volts for Single Phase), and provide a number of smoothing and stability functions. High Efficiency Inverters are designed to operate with very little loss.
[edit] Properties
The inverter type of High Efficiency Inverters is HighEfficiency.
The inverter efficiency is 0.98 [1].
The efficiency improvement rate is 0.02 per annum [2].
For inverters installed to solar generation systems, the cost per Watt for high efficiency inverters is $2.00/Watt [3].
The expected cost decrease rate for the price of High Efficiency Inverters is 0.03 Matthew Sullivan </ref>.
Yearly operational and maintenance costs can be expressed in terms of the first, or capital, costs of the inverter. For High Efficiency Inverters, the Operation Cost as Percentage of First Cost is 0.02 [4].
Due to wear and tear, hardware needs to be replaced after a certain period of time. The replacement period of High Efficiency Inverters is 10 years [5].
The replacement cost is the percentage of the initial capital cost of the hardware that in incurred when the device requires replacing. For the inverter it is 1 [6].
