110 V from a 220 V Inverter

[coldspot]

 I have a friend that just set up a China Turbine-

"wwwcbpwt.com"

"HS1kw" at 48 Volts

 This set up came to him with a 220 VAC- 48 VDC Inverter.

(BSE P-800){I thought it said made in USA?}

 The unit has two outlets for 220 AC that each only have the two 110 V legs without a ground.

 He'd like to take 110 VAC off of it and I can't think it out to work without the ground?

Because he just switched to 48 he has no other stuff for that voltage yet.

 The Turbine itself looked pretty nice with a rubber block built into the rear end for the side furling to hit against in either direction with the tail vane pipe hooked to a built in angled rod to ride on.

 The vane seemed a bit small to me.

 The blades are 110"

 I've seen 7 amps in average winds on its gauge

 He said he's seen 10 in better winds and also said he saw it furl a little in hard gusts.

 he put on a WAY to small of a tower, about 30'.

I might post a few pictures later.

Thanks for any thought or advice on the inverter!

There are adaptors sold for converting European 220  for use with US appliances. They come with numerous plug types. They generally sell for about $10 on greedbay.

 See if there is a ground area for grounding the inverter. Then with lots of luck they will tell you in the manual that is your ground for the whole system. On my inverter the grounds are all the same. You should be able to ground the inverter and hook your ground for power cord there too. It's Chinese to me.

 If it's 220 v a/c 60 hz,, (us system) that should be easily possible, but if it's 220v a/c 50 hz (european) probably not.. sounds to me like he got the wrong inverter.. i'd have to see the plugs, and the frequency rating.. more info is needed here.

 A better link to the Turbine site-

"www.sentex.net/~sxing/generator/generator.htm"

 I get more info from him tomorrow maybe.

Thanks

 After looking it over again

it's a 220v a/c 50 hz

I told him to tell the seller that they messed up and should replace it.

 The turbine has been acting up,(seems unloaded to me), getting turned around and running with the tail into the wind not the blades.

 One day with good winds while I was there, we roped the tail and turned it around and while he expected it to spin the blades the other way I knew that they where spinning the right way and in less than a half hour it got spun back around to be running tail upwind.

 Vain way to small, IMHO.

 I have not caught him home again yet, I think a burnt stator or maybe the connections up top unhooked??

 Today, I caught my friend home,(lets just call him KJ).

He has his turbine down, and has found the problem.

"the connections up top unhooked"

 I was right, well sort of.

This turbine head, the alt to the rear slip ring housing was assembled wrong. By just one bolt hole!!

 The alt's three wires leave the rear via a plug hole about half way to the side of the alt body.

When this was put together they had this plug hole directly inline with the slip ring pole inside the rear end. if turned either way by just one bolt hole this would have not let the two upper rings wires rub against the lower ring and thats where they got worn enough to when short the alt out and when heat up the brush holder enough to have it melt enough to have one brush fully fall out and the other two lean down by one full ring. the two upper rings wires heated till the became un-soldered from the ring holder then flopped around inside shorting when ever they touched anyplace.

 KJ has called the importer/seller and was asked to e-mail pictures to them, and he has done so.(I reminded him to ask about the wrong 50Hz inverter).

 KJ said he tested the windings with his meter and said one phase was open.(I tested only by touching each of the three to only one other and test turning the blade shaft. Anyway I had it hooked up it would become very hard to turn???)

 When my turbine gets caught tail to wind, "because of wind change after a calm night" the blades spin backwards slowly till the wind catches the tail to spin her back 180 deg. Then the blades spin the other way. Its a big difference in blade performances which side is to the wind.
