Technical FAQs 4

What size inverter do I Need?

Inverters come in different sizes starting from as little as 125 watts. The typical inverter sizes used for residential and commercial applications are between 1 and 10kW with 3 and 5kW sizes being the most common. With such an array of options, how do you find the right size for you? An inverter works best when close to its capacity.

What are the different solar inverter sizes?

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. During our research, we discovered that most inverters range in size from 300 watts up to over 3000 watts. In this article, we guide you through the different inverter sizes.

How much power does a solar inverter need?

Combine your findings: Highest Surge: e.g., 600 W from fridge. → Recommended Inverter Size: 1,200 W minimum. If you later add an air conditioner (2,400 W surge), you’d bump up to a 3,000 W inverter—like the Lefor 3000W in the Lefor Solar Inverter Series.

How does the inverter size calculator work?

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.
