[QUOTE="Berserkerboy, post: 529473, member: 34792"] Yes. If you're retrofitting you'll have a better idea of size battery you need. We use around 3kwh/day from the grid during the sunnier months. I also looked at our production during the other months as it would be pointless overspending on a bigger battery that won't get filled up. I've decided on a 5kwh battery and 3kw AC coupled inverter (around £2000). My grid usage for the majority of the year will hopefully be...zero!:cool:. At the moment, I know that the economics of installing the battery are only just making sense. However, if prices continue to spiral as appears likely, then that will change. Also, the battery will mean that we won't have to time using high-consuming items with the sun being out. That'll make life a bit easier. I also recognise that winter months will require most of our power to come from the grid, as will be the case with most systems. [/QUOTE]
