    How big should a solar inverter be?

    Generally, it's recommended to size the inverter to 80-100% of the DC system's rated capacity. Before determine the inverter size, the most important thing is to calculate your average daily power consumption (kWh) and calculate your solar panel array size to match your power consumption. You could follow our to make this estimation.

    How to size an inverter?

    If you want to know how to size an inverter, the answer is simple. All you have to do is find out how much power your devices need. Then, do some simple math to determine how much more power you need to compensate for inverter losses and headroom.

    What is a recommended inverter power range?

    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. This approach ensures that your inverter is neither under-sized—risking energy losses and performance issues—nor over-sized, which can lead to unnecessary costs.

    How to choose the right inverter power?

    Avoids Overloading: By selecting the right inverter power with a safety margin, you prevent overtaxing the system and potential breakdowns. To guarantee a reliable power supply, it is essential to align the continuous output of the inverter with or surpass the total wattage requirements of all connected devices.

    Do I need a 3.6kW inverter for my solar system?

    Sometimes, installers might suggest a 3.6kW inverter even if your system requires a larger one.
