One of the most common questions we get is “how big a solar system do I need?” The honest answer depends on your monthly electricity usage, roof space, and whether you want full backup or just cost savings during the day.
As a rule of thumb, a 5kW hybrid inverter with a 5kWh battery suits an average household running lights, wifi, TVs and a fridge through an outage. Larger homes or businesses with pools, geysers or air-conditioning typically need 8kW–12kW systems with 10kWh or more of battery storage.
