Use a center-tap transformer rated for 220V output and 12V input with at least 100W capacity. This configuration works best with a 12V lead-acid battery and two IRFZ44N MOSFETs or equivalent.
[pdf] Note!The battery size will be based on running your inverter at its full capacity Assumptions 1. Modified sine wave inverter efficiency: 85% 2. Pure sine wave inverter efficiency:90% 3. Lithium Battery:100%.
[pdf] Yes, you can use a LiFePO4 battery (Lithium Iron Phosphate) for an inverter, provided that the inverter is compatible with the battery’s specifications. LiFePO4 batteries are increasingly popular due to their high energy density, long cycle life, and safety features.
