Common sizes range between 1kW and upwards over 10kW. In order to accurately size your inverter, here is a very simple formula: projectiles. Inverter Size = Total Solar Panel
Inverters come in standard sizes like 3kW, 5kW, 6kW, 8kW, and 10kW. Round to the nearest size—in our example, choose a 5.5kW or 6kW solar inverter for home use. A
Picking the right solar inverter isn''t rocket science, but it''s not a wild guess either. Match your inverter size to your solar panel output, leave a little headroom, and don''t cheap

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.
It's a common misconception that inverter size should match your home's energy usage. In reality, it's your solar array's output that matters. 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.
Depending on where they fall in that band and the size of their solar array, they will likely use a 3, 5, or 10kW inverter. You also need to consider surge watts and voltage drop. Surge watts are the extra power required to start appliances that have motors, such as refrigerators and air conditioners.
Our Inverter Size Calculator simplifies this task by accurately estimating the recommended inverter capacity based on your solar panel power and quantity. By inputting your panel's rated power and number of panels, the calculator produces a recommended inverter power range that aligns with 80-100% of your system’s total DC capacity.
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.
