What Size Inverter Should I Buy?
- Sizing the right power output. Inverters will be rated by a wattage value, telling you how many watts it can run at one time. For example, imagine you had a 500W Fridge and 800W Air Conditioning. These two items would be 1300W and would require an inverter with a higher wattage than 1300W. An inverter above 1300W can meet your power needs. (The calculation methods of variable frequency and fixed frequency are different.)
- Check your battery voltage. The DC voltage rating on the inverter will tell you what battery bank it is compatible with. For example, a 12V battery bank will require an inverter that is compatible with 12V DC input.
- Size your installation spaces. What area or space will you set your inverter? Make sure the inverter will fit in the space you have in mind with enough room around it for proper ventilation and no fire hazards.
- Not sure where to start? If you don't know much, we will provide you with one-stop service.
