How big a battery do you need for Stage 4?
Start with the essentials list. Everything else is comfort, not survival.
A 5 kWh pack can keep lights, wifi, and a fridge alive for a few hours if you are disciplined. A 10 kWh pack buys breathing room. Running the geyser and oven off battery is how quotes explode.
A useful order
- List what must stay on during outages
- Add watt hours, not vibes
- Size solar so the pack can recharge on a cloudy day
