[QUOTE="binky, post: 538053, member: 490"] 10 kw battery, will supply 1 kw for 10 hours, 2kw for 5 hours, and so on, so powering the whole house for any length of time is going to need a very big battery Indeed! The EPS is automatic on grid fail, and will supply whatever is connected to it, but output is limited to give a reasonable battery life. You can do whole house, but you need a changeover switch on the incoming supply to protect whoever is trying to fix the fault, and stop you supplying all your neighbours. There are automatic changeover switches available, but you would have to look for one as I've never fitted any. Personally I would fit a manual unit, that way you know you are on battery only, and can switch off non essential loads, like the jacuzzi. [/QUOTE]
