Battery or rationing? A user weighs backup for a 7.6 kW solar array

📍 Reddit SolarEnergy

Unconfirmed: A Reddit user says his 7.6 kW SolarEdge array was out of service for six days after Milton, because he skipped a battery in 2019. His installer offered one and he deferred. He is now weighing backup for the fridge, router, ceiling fans and a bedroom mini-split, averaging about 0.7 kW (roughly 17 kWh per day). By his calculations, a 10 kWh battery would cover about 14 hours of that load, and on a normal sunny day the array would produce more than he uses. The post cuts off before stating his conclusion on whether to buy a battery or buy more kWh and ration them.

🔎 Why it matters: Unconfirmed: these are one user's calculations, not data from SolarEdge or his installer. The discussion centers on concrete figures, a 7.6 kW array and a 10 kWh battery, against a backup load of about 17 kWh per day.
📈 Upside: By the author's account, a normal sunny day produces more energy than the 17 kWh per day the backup load would use.
📉 Risk: With 10 kWh and about 17 kWh of daily consumption, the battery would run out in under a day without solar recharging.
