Solar Inverter Sizing Guide: How to Size Your Inverter
Learn how to properly size your solar inverter with our complete guide. Discover the optimal DC-to-AC ratio and avoid costly sizing mistakes.
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.
Inverter: one or two inverters of a combined 10 kW–15 kW A 12 kW solar installation in a farm near Berlin utilized a 10 kW inverter with excellent results—saving a couple of hundred dollars on initial cost and still registering peak output. 3. Equate Load Requirements, Not Panel Watts It's not solely about sunlight—actual usage matters, too.
Most UK homes need at least a 5 kW inverter. While 3.68 kW is common, larger homes or those with batteries benefit from a 5 kW+ system. What is a solar inverter? A solar inverter converts electricity between “direct current” (DC) and “alternating current” (AC). Electricity produced by solar panels and electricity stored in batteries is DC.
