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.
To account for power losses assume an 80 percent efficiency. 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 rule of thumb is to size your inverter 1.25 bigger than your solar array.
Inverter sizing for solar installations is a three-fold process: analysis of one’s needs and the matching of those needs with the outputs of solar panels, considering growth in the future. As systems like the Growatt hybrid inverter become more popular, correct sizing becomes paramount to assure performance, reliability, and efficiency.
When sizing an inverter, calculate the total wattage needed and understand surge vs. continuous power. Choose the right size with a 20% safety margin. Factor in simultaneous device use and peak power requirements and add essential margin for future power needs and system upgrades.
This is the most critical factor in solar inverter sizing. Check the total wattage of your solar array (DC) and use it to calculate the appropriate inverter output (AC). For optimal results, a 6.6kW array typically pairs with a 5kW inverter, falling within the accepted array-to-inverter ratio of 1.15 to 1.33.
Oversizing or having an inverter that is too big for your solar panels will not produce enough electricity. Undersizing or having an inverter that’s too small will convert a limited amount of energy. You can avoid both of these scenarios by following these three basic steps to solar inverter sizing.
