    5 What Size Inverter Should I Buy?
    • 1.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. (The calculation methods of variable frequency and fixed frequency are different.)
    • 2.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.
    • 3.Size your installation spaces. 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.
    • 4.If you don't know much, we will provide you with one-stop service.
