Secret plug-in grid-connected photovoltaic inverters

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 gridinverter 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 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 withanti- 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 .
