A quick rule is to divide watts by 10 for 12V systems or 20 for 24V systems. For more accuracy, divide the load by the actual battery voltage and adjust for inverter efficiency (typically 85%).

If you need an inverter of 2000W or larger we recommend you find an inverter built for 48V DC, even if this isn't easy to get locally. See “Why 48V is Better” below for the reasons why. You build up voltage by putting two or more identical batteries in series.

For most single battery setups, a 1000W pure sine wave inverter is the safest, most practical match.

- Rule of Thumb: The inverter's rated power (kW) should align with the battery's capacity (kWh). - Oversizing the battery can lead to underutilization, while undersizing may limit performance.
