Low 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. Low Efficiency Inverters operate with slightly larger losses than other inverter types, but have lower capital costs.

[edit] Properties

The inverter type of Low Efficiency Inverters is LowEfficiency.

The inverter efficiency is 0.91 [1].

The efficiency improvement rate is 0.02 per annum [2].

For inverters installed to solar generation systems, the cost per Watt for Low Efficiency Inverters is $1.50/Watt [2].

The expected cost decrease rate for the price of Low Efficiency Inverters is 0.04 [2].

Yearly operational and maintenance costs can be expressed in terms of the first, or capital, costs of the inverter. For Low Efficiency Inverters, the Operation Cost as Percentage of First Cost is 0.02 [3].

Due to wear and tear, hardware needs to be replaced after a certain period of time. The replacement period of Low Efficiency Inverters is 10 years [4].
