The prices are quoted for 2024/2025, currency is avoided as EUR, USD and GBP are roughly the same, local taxes might have a bigger impact than exchange rate. The goal is to have the best price-to-performance ratio as possible without the need to go off-grid. It also means that small outages (<24h) can be mitigated. I am presenting the calculations for my needs but you can scale up for your home. Preparation First you need to determine your house base load. This means the hourly average for 24h, in my case this is around 130W/h, so fridge, servers, cameras, central heating, around 3-5kWh per day when nobody is home.
