- 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. . When using high-performance lithium iron phosphate (LiFePO4) batteries, selecting the correct inverter is not just a recommendation—it's essential for safety, efficiency, and longevity. The. . An inverter is the device that converts direct current (DC) stored in a lithium battery into alternating current (AC) used by most appliances and electrical systems. The formula is: Inverter Size (Watts) = Total Load (Watts) / System Voltage (48V).
