Eduardo,
Did you forget the link mate?

 Good on you George, keep us posted on your progress, here is a link for a search on Vanadium redox batteries, they were invented in Au. the Howard Gov. failed to promote them but they are still around.cheersEduardo

 Eduardo,
Thanks for the advice mate.  I have 2 of these 15 kw 3 phase inverters in parallel and I'm looking to get off the grid altogether.  I don't want to switch back to the grid.  I have 24 kws of solar panels, 96 panels in all and I have a couple of generators and I want to get a battery bank etc.

 I think that grid tie inverters use the grid to chop up the DC so that the frequency is synchronized and doesn't clash with the grid, so to stand alone they would require added circuits to create the alternating frequency, may be it would be easier to use a stand alone inverter for off grid use and switch to the grid tie one when you want to export surplus to the grid.cheersEduardo

Anyone got any experience of modifying SMA Tripower 15kw grid tied inverters to stand alone off the grid?
Thanks in advance for any advice.
