What Size Inverter Should I Buy?
- Size the right power output. Inverters are rated by wattage, telling you how many watts they can run at one time. For example, a 500W fridge and 800W air conditioner total 1300W — you would need an inverter rated above 1300W. (Note: calculation methods differ for variable frequency vs. fixed frequency loads.)
- Check your battery voltage. The DC voltage rating on the inverter tells you what battery bank it is compatible with. For example, a 12V battery bank requires an inverter compatible with 12V DC input.
- Size your installation space. Make sure the inverter fits in your chosen space with enough room around it for proper ventilation and no fire hazards.
