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.
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.
Match your inverter to your lifestyle, not just your roof. If you’re running a fridge, home office, and PS5 all day, size accordingly. If you’re barely home, go leaner. Here’s the cheat code: your inverter size should usually match your solar panel system’s size in kilowatts.
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.
The continuous power requirement is actually 2250 but when sizing an inverter, you have to plan for the start up so the inverter can handle it. Third, you need to decide how long you want to run 2250 watts. Let’s say you would like to power these items for an eight-hour period.
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. This approach ensures that your inverter is neither under-sized—risking energy losses and performance issues—nor over-sized, which can lead to unnecessary costs.
