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.
A 4.5 kW array (or ten 450-watt solar panels) would just about cover your consumption. The type of solar panels you choose can also impact the size of the inverter you need. Different types of solar panels have different wattage ratings and efficiency levels. The three main types of solar panels are monocrystalline, polycrystalline, and thin film.
Luckily, there’s a quick and easy way to calculate the size of the solar panel inverter you need – using a Solar Panel Inverter Size Calculator. Here’s how it works: 1. Enter the total wattage of your solar panels. 2. Enter the maximum wattage output of your chosen inverter.
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.
