Important Considerations When Buying:
- Pure Sine Wave vs. Modified Sine Wave:
- Pure Sine Wave: Essential for sensitive electronics (laptops, medical equipment, power tools with variable speed, laser printers, certain battery chargers) to prevent damage and ensure optimal performance.
- Modified Sine Wave: Suitable for basic appliances like lights, fans, heating elements, and phone chargers that are not sensitive to power fluctuations. Avoid for anything with a motor or delicate circuitry.
- Continuous Power vs. Peak Power:
- Continuous Power: The maximum power the inverter can deliver constantly. This is the most important rating.
- Peak Power (Surge Power): The maximum power the inverter can provide for a very short duration (milliseconds), typically for starting motors or compressors. Ensure the inverter’s peak power is higher than the starting surge of your highest-demand appliance.
- Efficiency: Higher efficiency means less power is lost during conversion, resulting in longer battery life. Look for 85% or higher.
- Safety Features: Essential protections include overload, over-voltage, under-voltage, over-temperature, and short-circuit protection.
- Cooling: Inverters generate heat. Good cooling systems (often smart fans) are crucial for longevity and performance.
- Connection Type: Smaller inverters often plug into a cigarette lighter socket (limited to around 150W). Higher wattage inverters require direct connection to the battery terminals with appropriate gauge cables.
