Frequently Asked Questions
What is the difference between pure sine wave and modified sine wave inverters?
Pure sine wave inverters provide smooth, clean power similar to utility grids, suitable for all electronics. Modified sine wave inverters are cheaper but may cause humming or overheating in sensitive devices.
Do I need a separate battery charger with an inverter?
It depends on your needs. If you have an inverter/charger combo, it is built-in. Otherwise, you need a separate charger to recharge your batteries when not running.
How do I size an inverter for my boat?
Calculate the total wattage of all devices you plan to run simultaneously. Add 20 percent to that number and choose an inverter with a continuous rating at least that high.
Can I run an air conditioner with a marine inverter?
Only high-wattage inverters with sufficient surge capability can run air conditioners. Typically, you need a 2000W to 3000W true sine wave inverter for this purpose.
What safety certifications should I look for?
Look for UL458 with marine supplement, ABYC, or CSA certifications. These ensure the unit meets strict marine safety and electrical standards.
