Perfectly Size Your Inverter for Peak Output | EcoFlow US
Most solar professionals recommend sizing your inverter for solar panels between 75% and 115% of your total panel wattage, with the sweet spot around 1:1.15 —meaning your
Your inverter size should match your solar array's capacity, not your electricity bill. This means your inverter doesn't need to power your entire home—it just converts whatever your panels generate. Let's say you have a 6kW solar array (twenty 300-watt panels).
The need for an inverter size chart first became apparent when researching our DIY solar generator build. Solar generators range in size from small generators for short camping trips to large off-grid power systems for a boat or house. Consequently, inverter sizes vary greatly.
Ideally at 80–110%, to compensate for panel overproduction in bright sunlight and to avoid compromising inverter efficiency. 2. Select an Appropriate Inverter Rating Here's how inverter sizes usually correlate: Panels: 3,000 – 6,000 W Inverter: 3,000 W to 5,500 W Panels: 6,000 – 10,000 W
Oversizing or having an inverter that is too big for your solar panels will not produce enough electricity. Undersizing or having an inverter that's too small will convert a limited amount of energy. You can avoid both of these scenarios by following these three basic steps to solar inverter sizing.
