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.
Interpreting Results: Once you input the required data, the calculator will generate the recommended battery size in ampere-hours (Ah). For instance, if your power consumption is 500 watts, the usage time is 4 hours, and the inverter efficiency is 90%, the calculator might suggest a battery size of approximately 222 Ah.
For a 12V 200Ah battery (2.4kWh), a 2000W inverter is ideal. Formula: Inverter Wattage ≤ (Battery Voltage × Ah Rating × 0.8). Factor in surge power needs but prioritize sustained loads. Always check the battery’s max discharge rate (C-rate) to avoid exceeding safe limits. When sizing for 24V or 48V systems, recalculate using the higher voltage.
