Wondering what size solar inverter do I need for your solar system? This guide walks you through calculating inverter size based on panel capacity, power usage, and safety margins.

Generally, it's recommended to size the inverter to 80-100% of the DC system's rated capacity. Before determine the inverter size, the most important thing is to calculate your average daily power consumption (kWh) and calculate your solar panel array size to match your power consumption. You could follow our to make this estimation.
A solar inverter sizing calculator is a tool used to determine the appropriate size of a solar inverter for your solar power system based on the total power consumption of connected appliances and the size of your solar panel array. It ensures the inverter can handle the peak loads efficiently.
Total capacity = 20 x 500 = 10,000 watts or 10 kW The industry standard suggests that the inverter’s capacity should be between 80% to 125% of the solar panels’ capacity. For example, if your panels generate 10 kW: Minimum inverter size = 10,000 x 0.8 = 8 kW Maximum inverter size = 10,000 x 1.25 = 12.5 kW
For most home and portable PV systems, you will only need one inverter if you are using either a string inverter or power optimizers for the solar array; if you use micro-inverters, you won’t require a standalone inverter all as they convert DC to AC at the panel.
Add up the wattage ratings of all your solar panels. For instance, if you have 20 panels, each rated at 500 watts, the total DC capacity is: Total capacity = 20 x 500 = 10,000 watts or 10 kW The industry standard suggests that the inverter’s capacity should be between 80% to 125% of the solar panels’ capacity.
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.
