The need for an inverter size chart first became apparent when researching our DIY solar generator build. Solar generators range in size from small generators for short camping trips to large off-grid power systems for a boat or house. Consequently, inverter sizes vary greatly.
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.
The size of a solar inverter is crucial because it determines how much energy can flow to your home and battery at any given time. More specifically, the inverter ensures that enough energy can flow from your solar panels to the grid and load or if installed with a battery, from and to the battery.
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.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
