FAQs 6

What size solar inverter do I Need?

Inverter size is measured in kilowatts (kW). It should match your solar array within a 1.15 to 1.33 ratio. Getting it wrong can reduce efficiency or disqualify you from solar rebates. What size inverter do I need for solar panels? To calculate, divide your solar panel system’s total DC rating by the desired inverter’s AC output.

Can a solar inverter be bigger than the DC rating?

The size of your solar inverter can be larger or smaller than the DC rating of your solar array, to a certain extent. The array-to-inverter ratio of a solar panel system is the DC rating of your solar array divided by the maximum AC output of your inverter. For example, if your array is 6 kW with a 6000 W inverter, the array-to-inverter ratio is 1.

What is inverter size?

Inverter size refers to the maximum amount of power that an inverter can handle and convert from DC (Direct Current) to AC (Alternating Current). It is typically measured in watts or kilowatts. The size of the inverter you need depends on the total power consumption of the devices you want to run.

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.

What is a solar power inverter?

A solar power inverter is an essential element of a photovoltaic system that makes electricity produced by solar panels usable in the home. It is responsible for converting the direct current (DC) output produced by solar panels into alternating current (AC) that can be used by household appliances and can be fed back into the electrical grid.

What is the array-to-inverter ratio of a solar panel system?

The array-to-inverter ratio of a solar panel system is the DC rating of your solar array divided by the maximum AC output of your inverter. For example, if your array is 6 kW with a 6000 W inverter, the array-to-inverter ratio is 1. If you install the same-sized array with a 5000 inverter, the ratio is 1.2.
