Hi,
With predicted winter costs of electricity in uk set to reach £1 kw this winter, it seems to me that it is worthwhile running a generator to charge batteries through an Easy solar with panels. As the panels will likely be insufficient in winter, the generator will be run for a couple of hours a day. The grid will not "fail" as such to switch to the generator. To make this work wil it be correct to install a mains switch to manually isolate the grid and switch on the generator . Looking at 6kva generator, Easy solar 5kva. Many thanks in advance , Jamie
