[QUOTE="johnb2713, post: 533518, member: 35153"] I have no intention of reducing anything if I go off grid. My system will have 21kWh of storage and 11 kW of inverter capacity, both probably expanded if I do make the jump. The Red Diesel bit I can understand hence why I would be using Bio Diesel made in my Bio Buddy from used cooking oil, it shouldn't cost much more than 20p per litre of fuel. Using the generator as part of a Combined Heat and Power bring massive economies to the project. I'm guilty of installing solar and battery as a result of rising prices. Octopus informed me my direct debit needed to be raised from £178 per month to £565 per month, I ran my meter reading through a spreadsheet and found that £465 based on last years consumption would be nearer the mark. Even at £465 it's acceptable to me so a search for solar and battery was undertaken. Through the summer our actual energy bill for both gas and electricity has been around £65, through the summer a saving of £400 per month is very nice. I know it's going to drop in wintertime like a stone, but even so, our break even is going to be around 3.7 years if prices remain as they are. We do make use of Octopus GO and charge the battery overnight, the system uses a substantial amount of battery power before and after solar PV waking up / going to sleep. I think the real secret in getting the best out of these systems financially is a good off peak tariff, a decent size inverter 10kW+ and a decent amount of battery storage. [/QUOTE]
