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.

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.

How to calculate inverter size?

Using the Inverter Size Calculator is quick and easy. You’ll need three inputs: Total Wattage (W): This is the total power consumption of all the appliances or devices you plan to run through the inverter. Safety Factor: A multiplier to ensure some buffer above your actual power requirement. Typically ranges from 1.1 to 1.5.

What is a 3 phase inverter?

Three-phase inverters convert DC to three-phase AC power and are typically used in industrial and commercial settings with higher power demands. Power requirements of appliances: Determine the wattage of each appliance you'll use with the inverter.

What factors affect solar inverter size?

The two primary factors affecting solar inverter size are panel productivity and geographical location. A reliable solar provider like Plico will talk you through inverter options and help you find the best match for your system. What is a solar inverter? A solar inverter converts energy from solar panels into usable electricity for your home.

Why is inverter size important?

Here are the key reasons why inverter size is critical: Optimal Efficiency: If the inverter is too small, it will "clip" excess power when the panels generate more than the inverter's capacity, wasting energy. If the inverter is too large, it may operate inefficiently during periods of low solar production (e.g. early morning or cloudy days).
