Thank you very much,,... now I am sure that the above is very easy for you, but could you please outline that re-wiring in a very, very, simple, idiot way for me please

with your large PV array, I would look very carefully at finding a solution like Tarrel proposed earlier. This must be more cost effective than setting up a wind powered generator.

Even on e-bay there are a good number of high wattage charge controllers capable of 48v input voltages.

If you can devise a method to have these charge controllers swiched into the PV output ahead of the grid converter, you'll be able to charge and top up a 12v battery bank at will, with or without mains power coming into the property.

L.S... thanks,... one of the reasons for also looking at the wind turbine, is because in the winter we get very little daylight this far north, not getting light til about 9am and dark again by 4pm, worse on rainy, stormy days,.. so on these very low light days, the solar might simply not have the time to charge batteries,.... I am talking after an event now

... but I am looking at every option at the moment
