[QUOTE="Mrjmegson, post: 541593, member: 35426"] Start by working out how much energy you use a day, and when you use it. So e.g 10kwh a day, 7kwh in the evening, 3kwh during the day. Use this as the minimum size battery you want, so around 10kwh in this example. Then think about if you would like more capacity, to get you through x number of days of bad weather, if you're not on a time of use tariff where you can charge the batteries cheaply in the evening. If you are on a tou tariff, then I'd say you only need a battery big enough to cope with your daily demand. You also need to forward plan, are you going to buy air source heating in the future, or similar, so may increase your daily consumption. As far as the actual battery, you need to either look at your inverter manual, or speak to the supplier to find out what batteries are compatible with your inverter. Do you have a hybrid inverter, one that controls solar, battery charge/discharge, and powering your house? I'd guess not if it was free. So you will probably need additional equipment to charge the batteries. Hope this helps and I haven't made it sound too daunting. Jay [/QUOTE]
