5kws Of Inverter Per Phase

This is what you are allowed in most parts of the country, with a couple of exceptions in some areas granted with special approval.

However, recently we have been seeing people quoted 8kw inverters in Energex, and being told, in writing no less, which is actually criminal, that they can send all of the power back to the grid.

Let us clear this up now. You can only use 5kws of the inverters power unless you are using more than 5000 watts at once. Which, for most people anyway, is far more than they could ever utilize. And even if they do occasionally exceed 5000 watts, it wont be for long!

We had 3 customers yesterday that had been advised that they could send all the power back, and another who was told he could still export 5kws while using the extra 3kw as "that part kicked in first, and the rest will go back to the grid and you'll make money".

There's nothing wrong with having a zero export system, and indeed for some, it's the right thing to do. But please be aware that it will not all be utilized unless you have a very high usage at one time.

And beware of anyone who puts in writing that you can. They don't plan on helping you once you realize you've been had!
