Plug- grid PV inverter has emerged in Australia -
what they are, how they work, you should also use one ? PV inverter is an
electronic box will be solar panel array generates DC power (DC) into
alternating current (AC), applicable to home appliances, and transported to the
main grid .
Traditional solar inverters , solar modules
can handle multiple output , usually installed in the meter box nearby.
Micro-inverter , is a recently developed a new type of inverter, has a smaller
size, can work with a single solar panel and installation of solar panels on
the back on the characteristics , creating a commonly referred to as the AC
solar panels.
In the family system, install the most
common photovoltaic inverter requires a qualified electrician to operate,
because they are qualified to the wire connected to the meter . The new "
plug and play" inverters are very different - it is a portable device that
can be solar panels or small wind turbines connected to the inverter, then
directly into the family standard power inverter socket ; electricity for home
appliances . Although less than a standard residential solar inverter capacity
size, but can be used multiple units.
It sounds like a great idea , but consumers
considering the purchase of plug and play grid inverter may need to be careful
. In a forum on energy issues discussed at the problem, which is one point to
mention , although Clean Energy Commission (CEC) will plug the inverter
marketed renewable energy certificates and obtain approval (RECs), but in a
important safety standards , their certification still seems doubtful.
AS-4777 standard , is handling the inverter
connected to the grid energy systems and networks in the world. In order to
pass Clean Energy Commission (CEC) approved listing of pure sine wave power inverter " must AS
4777.2 and 3-2005 ( or equivalent ) and AS3100 ( or equivalent ) standard , in
a suitable test lab to get tested ."
However, in AS4777.1 ( installation
requirements, Section 5.3.1 ) , it is
clearly pointed out: "Inverter fixed wiring should be connected to the
distribution switch a dedicated circuit ." If strict compliance with the
AS-4777, which seems to avoid the use of any type of plug and play devices.
Another important issue relates to the
power distributor. Before the generator can be connected to the grid ( which
includes your house to install solar panels and electricity to the grid ) , to
obtain the approval of dealers is a must . This approval is not just a brief
telephone or verbal , "Yes, you can do " can decide - but need to
have paperwork identified .
In addition, the safety of these
individuals has also been improved . Plug and Play with anti- islanding
inverter functions and features to prevent individuals continue to provide
power during a power outage ( because electricity will continue to supply two
seconds ) . If the plug from the power outlet , it can still be released
instantly to mention electricity.
Finally, consumers consider installing a
plug and play grid inverter , and insurance companies should be confirmed to
ensure the proper use of this device does not affect the home insurance
coverage , especially as a DIY project .
While in theory is a great idea , but it's
these potential problems have led some people to use plug and play inverter
concept.
