2. Peak power requirements: Some devices need more power to start than to run continuously. For instance, a refrigerator may require 300 watts to start but only 150 watts to run. You should account for these peak demands. A general guideline is to add an extra 25-50% to your total wattage for startup surges.

3. Inverter efficiency: Inverters have operating efficiencies that determine how much input energy translates to usable output energy. Most inverters have efficiencies between 85% to 95%. If you have a total wattage of 300 watts needed and your inverter operates at 90% efficiency, you need at least 333 watts (300 watts / 0.9) from your battery.

4. Output type: Inverters come in two main types: pure sine wave and modified sine wave. Pure sine wave inverters are better for sensitive electronics. They provide cleaner power and are often more efficient. Modified sine wave inverters are cheaper but may not work well with all devices. Assess the type of devices you will run and choose accordingly.

5. Future considerations: Think about potential future power needs. If you anticipate adding devices, consider selecting an inverter with a higher capacity. This approach can save you from needing to purchase a new inverter later.

6. Battery compatibility: Ensure your inverter is compatible with your battery type and voltage system. Most van conversions use 12V systems. Check the inverter’s input voltage requirements to avoid mismatches.
