Micro Grid Tie Units Feedback

[infringer]

I am curious if any of you folks have used micro grid tie units ...

I have heard of a few people who swear by the swiss units like this one:

But I am curious about the cheaper units featured on ebay like the chinese units on ebay...

Anyone using micro grid tie please post your feedback I would greatly appreciate it.

I have not seen this type unit before i mean manufacturer but there are different types and some are good and some aren't worth a nickel in my opinion. some have to be tied to the grid for a while and make a consistent power level for about five minutes before they will output any power to the grid so they run but any fluctuation or drop starts a recount mine charges a cap bank and when it has enough for a pulse it sends it of there is enough for full time running it just keeps putting out so at this point i am fairly happy it does 1 KW max but am looking to do better.

Thanks for the kind reply.

yeah, their cute cute I suppose.

Every bit helps.

Here is some manufacturer info:

Yes Nueview,
You bring up a good point that may escape others.

The use of any small grid-tie inverter
should always be done through an intermediate storage source
Like a battery bank, or "Stiffener" capacitor bank.

Letting the feeble amount from any energy solar source
like wind, solar, etc. feed the inverter directly is a waste.

The small amounts they produce at times,
and sync plus delay circuits, etc.,
will waste most of your energy
under spinning the power meter.

Always build it up first,
then run at the inverters max.

An inverter idling has a horrible efficiency rating.

They are most efficient near the top of their max out.

So, build up, THEN drain out at full force to the grid.

to Compututor
thank you for understanding my reply and clarifying it for me to others.
yes the system needs to be run near max input and then becomes quite efficient otherwise they are not worth doing at all and could cost more to have than they are worth for the installation.
