We’ve been running a fairly solar‑heavy setup for a while now — multiple panels, a 25 kWh home battery, an EV, and most appliances converted to electric — and one thing I’ve learned is that the tech is only half the story; the real gains come from tracking and planning. A few things that might help anyone thinking about off‑grid or backup systems: • Forecast‑based planning makes a huge difference. We track the solar forecast and our expected usage day‑by‑day, which lets us shift heavy loads (washing, charging, cooking, water heating) into the sunniest windows. It’s surprising how much this reduces the need for grid backup. • Home Assistant has been a game‑changer. It pulls in live solar production, battery state, EV charging, and appliance consumption, so you can actually see where your energy is going. Once you have that visibility, it becomes much easier to size panels, batteries, and inverters realistically. • EV + home battery = flexible backup. Even if you’re not fully off‑grid, having both gives you options: the house can support the car, and the car can support the house (depending on the model and inverter setup). For anyone building a preparedness setup, I’d say: start with visibility and data. Once you understand your real usage patterns, choosing the right generator, solar kit, or battery becomes much simpler — and usually cheaper. Curious if anyone else here is using Home Assistant or similar tools to manage their energy?

We learned the hard way last year that having solar isn’t the same as being off‑grid ready. Our PV system was happily producing — lights blinking, battery almost full, sun shining — but the house was completely dark during the outage. It’s a strange feeling watching energy flow past you while you can’t use a watt of it. Even the neighbours came over asking if they could store things in our fridge/freezer… which of course had no power either. That experience pushed us to upgrade: new panels, a larger battery, and most importantly an off‑grid/backup switch so the house can isolate from the grid and keep running. Once that was in place, the system worked so well that the neighbours were the ones telling us when the grid was down — until I set up Home Assistant to notify us automatically. For anyone building a preparedness setup, I’d really recommend thinking not just about storage, but about how your system behaves when the grid disappears. It’s the difference between “solar as a nice bonus” and “solar as real resilience.” If anyone here is trying to figure out off‑grid switching, battery sizing, or energy monitoring, happy to share what we’ve learned.
