Your solar inverter should have a similar or slightly higher wattage rating than the DC output of your solar panels (which in this case is 4.5 kW). You can size it between 1.15 and 1.5 times larger.

The general guideline is to choose a solar inverter with a maximum DC input power of 20-35% greater than the total capacity of the solar array.

When sizing an inverter, calculate the total wattage needed and understand surge vs. continuous power. Choose the right size with a 20% safety margin.

The inverter’s capacity should ideally match the DC rating of your solar panels in kilowatts (kW). For example, if you have a 3 kW solar array, you would typically need a 3 kW inverter.
