Contemplating getting a 5 kw battery for my 4.5 kw solar system 10 panels just about to be put in .
if I use a 9 kw a day does it mean a 5 kw battery fully charged will supply me with half a days energy.or should I bother with a battery hoped to use battery outage in the evening for tv kettle etc .
