To effectively determine the number of solar panels an inverter can handle, you must first assess the size of your solar panel array. The overall capacity of your solar installation is defined by the wattage and number of panels. You can expect that the inverter should match or slightly exceed the combined wattage produced by the solar panels.
You will also need to consider the wattage of the solar panels you plan to use. For example, if you have a 5 kW inverter and each of your solar panels is rated at 300 watts, you can calculate the maximum number of panels by dividing the inverter’s capacity by the panel wattage: 5,000 watts (inverter) / 300 watts (panel) = approximately 16.67.
You can expect that the inverter should match or slightly exceed the combined wattage produced by the solar panels. Therefore, if you have an array of 20 solar panels, each with a capacity of 300 watts, the total output will be 6000 watts, which is an important benchmark for choosing your inverter.
Most string inverters have 3 inputs that can hold 8 panels each for 24 in total. The specifications will vary so make sure to check the inverter before connecting any solar panel. Generally, an inverter can handle up to 30% more power than its rating. Given that solar panels do not always produce at peak power, this should not be an issue.
If an inverter has a maximum input voltage of 600V and each panel produces 40V, you could connect up to 15 panels in series (15 x 40V = 600V). Going over this voltage limit can harm the inverter or make it shut down, making your solar system less effective or even unusable. Equally important is the minimum input voltage.
The size of your inverter will ultimately be determined by the wattage of your solar panel array and the amount of power you want to produce. A 3000-watt inverter is a good choice for most households who want to use solar power.
