SSEG install commisioning form enrty

[laseylaser]

Hi
I'm filling in the above form for western power, and asks for the SSEG Rating ( Amps ) and power factor under normal running conditions - what do you enter here ?
Also asks for the " MAX Peak short Circuit Current - what do you put in please.

Cheers

should find seeg rating and PF on inverter datasheet.

Max peak short circuit current, i put down the perspective fault circuit current of that circuit.

Hmm, are you sure that's correct?

No, but not had any comebacks putting that down so far, any other suggestions what this may be? Isc of array??

Given that if you short circuit an inverter's output it cuts off then I think the answer is "n/a".

Look at some manufacturers type test certificates and they say something similar.

For instance from Power One (PVI-3.6-OUTD)
"SSEG Short Circuit Current Contribution Test
According to Clause C.4.6, as Photovoltaic SSEGs are inverter connected, they are deemed to automatically comply with regulations
and no further tests are required."

and from SMA (4000TL)
"Fault level contribution
As Photovoltaic SSEGs are inverter connected, they are deemed to automatically comply with regulations and no further tests are required"

I put "n/a" and have never had a comeback. It may say more about the rigour with which the forms are checked rather than the accuracy of the answer!

cheers bruceB, one less thing to worry about.
