feed the grid

Hi , as far as i can understand the Flexpower setup , there is a US version that can sent surplus power from PV to export to the national grid .... , but there is no European Version (230 Volt AC 50 Hz) that can do this , .....

Is there a way to enable this feature in the european Version ? I would imagine they are ( the Inverters) are n ot diffrent , and only the Grid feed feature dissabled in the european Version ( other regulations)

Thats a pitty , i have to say , and much more Grid connected people would go for a battery based gridtie idea ( for example in Germany) if there would be a easy way of exporting surplus in summer to the national grid and get some FiT payements for the exported units (not a lot anymore)

Any way it has something to do withGrid regulations of countries , but is there a way to enable that feed the Grid mode in the 230 Volt version ?

Thanks

While I am US based and my knowledge of European utility regulation is limited, it is my understanding that the GTFX....E family, the GVFX....E family as well as the Radian 7048E are all designed to sell excess energy back to the grid.

See page 8 on the product guide http://www.outbackpower.com/resources/d ... t_catalog/ for the Radian and page 25 lists the specs on the other inverters.

.... am back on the same idea , and have a question again :grin:

Can i connect say 2 FM 80 and 10 kw PV to a OutBack Flexpower One VFX3524 48V/230V and the PV is delivering good power .... the inverter can only pass on max 3000 watt to grid and/or house (am i right ?)

But for example , i have a huge battery , to absorb the excess PV as well , can i programm the Flexpower One to drain the battery at night as well into the Grid , beside the house loads ?

Thanx

It sound to me as if you might need 3 fm80s. This forum has a string caculator listed at the top on the index page. If it doesn't work, midnite solar has one for there classic controllers and it would be close enough to the outback to tell you if you have too much panels for two cc.

Hi , thanks , its more or less a theoretical question
Not too mucht to do with the chqargecontrollers
The question is , if i can feed the puplic grid from the battery , not only for household use , and sell the units to the Grid by draining the battery at night

Like said , its more or less a theoretical question , to harvest FiT payments 24 hour a day on a 4000 watt limited powerline , with a bigger PV

Thanks

My suggestion is to never use the battery except maby to draw it down and recharge it once a month for the batteries health. The batteries start dieing the second they are made. I think that there are studies that show it cost 35 cents per kwh you get out of a battery. And that is for just the battery not counting what everything else cost. If you make a mastake it cost even more. Your best bet is to keep the battery as full as posible and sell as much as posible to the grid.

Secondly if you discharge the battery you lose 20% of of the power you put back in. If all you want is to sell you would be better getting an inverter that doesn't even need batteries. Then you don't need charge controllers. Of course you also won't have power if the grid goes down. If you are worried about making money, buy just a gridtie inverter and get a generator for when the grid goes down. Then maby you can come out money wise.
My honest opinion.

PS But the answer is yes you could drain the batteries to the grid at night if you wan't to lose money.

No , i calculate with about 6 cent (Eurocent )

I just want to know , if any Outback Inverter can feed the national Grid from a battery !!!!!!

Did you see my PS? The answer is yes if you set the sell voltage low enough, it will drain your batteries to the grid!!!!!!!!!!!!!!!!!!!!!!

ok, thanks , i missed that PS

Is there something i can read or find in the manual ,about how much i can drain the battery to the grid and how an outback inverter knows ....

I guess selling surplus PV to the grid is regulated by Voltage parameters ..... above bulk charge voltage or near absorption Voltage , but when sun down , and my say 100 kWh Battery is charged and sits under this Voltage , how will the inverter know to drain the battery beside my houseloads as well to the Grid ?

Thanx

I am looking for FX3024E repair schematic, if any one have please email me, alternateenergi@yahoo.com
there are some resisters and capacitor demaged, and their values are not readable,

warm regards
