12v battery bank into a 250 watt grid tie inverter

[super windy]

Hi fellas

Just wondering if anyone could help me on a query that I have is it possible to connect my battery bank 12v to a suitable grid tie-inverter, that then plugs into the house's normal outlet plug and puts 250 watts into my mains, in theory slowing or turning back the meter, the reason for this is that I saw loads of grid tie inverters rated 250 watts for sale in the american e-bay, I live in the u.k.

This is my thoughts please,, do correct me if I am way off the mark as usual:

Just to clarify things this is all a 12v system, battery bank 7 batteries at 105 amp each one, a juta 16 amp solar controller, one 1000watt pure sine wave inverter, anyway the power plant consists of:

1) my 600 watts turbine and ametek 30v connected to my battery bank, also connected to this battery bank is 3 different panels one 40 watts, one 50 watts and the last one at 140 watts, this usually raises the voltage up to 14.40 in no time, from what I was seeing from this grid tie inverter: http://cgi.ebay.com/NEW-MICRO-GRID-TIE-SOLAR-WIND-POWER-INVERTER-250W_W0QQitemZ290350569645QQcmdZVie



wItemQQptZLH_DefaultDomain_0?hash=item439a3e18ad&_trksid=p4999.c0.m14

the working imput voltage starts from 14v up to 28v, so can I in theory charge my batteries past 14v then divert 250 watts to this grid tie inverter so that it will slow my meter down a bit or even turn it back, this, if at all possible is a good system as at least my batteries will be charged and after charged they could send the extra power to the grid.

What do you more experienced fellas think about this idea and what is the best way of doing this safely, also do you know or have experience with another better or more suitable grid tied inverter working off 12v.

another concern is does it shut off reliably when the grid is down, I don't want to hurt or harm someone working on the grid at the time of cutout.

Any help or advice will be greatly appreciated.

Hi,

I know of noting that is UK approved (G83) and runs from 12V.

The Soladin 600 (MasterVolt) starts at ~48V nominal, and is one of the lowest that I know.

See http://www.alternativetechnology.info/Soladin600datasheet.pdf

I wouldn't do it. It will never pay for itself and if it doesn't have the regulatory approvals and inspections if anything goes wrong, you are hosed financially, that is when you get finally out of gaol.

I see no UL, CSA, G83 or any other certs on it.

In the US, the NEC also forbids a plug in arrangement for a gridtie, like this inverter uses.
