Questions people ask
How much battery do I need to run a fridge for 72 hours?
A typical fridge uses about 1 kWh per day, so roughly 3 kWh plus a margin, or less with solar recharging.
Can this connect to my home wiring?
Only through a proper transfer switch installed by a qualified electrician. Never back-feed a socket.
