There is an interesting feature of grid tie inverters both practically and economically that is not unknown
but difficult for many people to use because it involves the carry capacity of a house circuit.
NOTE: A house must have a 2 way bidirectional meter or a SMART meter installed to measure
outoin !roduced enery" #$eed in tari$$ is almost usually worthless % somethin li&e only 'cents

1. Each house circuit is 10 amp @ 240v . This means it can carry up to 200w ! 2."w #.
2. The cost of wiring in an inverter makes its si$e binding and cannot be changed or altered or
removed at will.
There is a !lu in rid tie inverter that !lus into a normal house soc&et"
These inverters are %stackable& ' meaning they can be connected onto e.g. an %e(tension socket
board&.
)or purpose' there are also %plug in grid tie wind power inverters& that are specifically designed to
harness power from particular wind turbines of various voltages *+,-+ and si$ewatts,"w/s.
arely is there ability to harness cheap but effective products by strategy inclusive economics.
n this instance' it appears to be in a - capacity' and direct buying capacity.
The first part of the strategy is with wind power' it/s 24,3 day and night' the second is that through
direct usage when electricity is reuire to be consumed there is something producing electricity e.g. %to
prevent daw of electricity that is paid for from the mains grid5&

Typically' as a flat and non real world average' wind speed at wagga wagga from weather graphs shows

This means that at a height of 42 5 40 meters #where a wind turbine should be located*11 to 2 mps can
be added reasonably surely to obtain 7 8 3 mps at 1 meters tower altitude.
* total !lower end# common wattage output is around 700 watts of 240v *+ into the house circuit or si(
