Frequently Asked Questions
What size fuse do I need for a 2000 watt inverter?
For a 2000 watt inverter on a 12V system, you should typically use a fuse between 200A and 250A. This accounts for the maximum current draw plus a safety margin. Always place the fuse as close to the battery terminal as possible.
Can a 2000 watt inverter run a microwave?
Yes. Most small to medium microwaves consume between 800 and 1200 watts. A 2000 watt inverter handles this load comfortably. However, microwaves have a high initial surge, so ensure your battery bank can sustain the heavy current draw.
Pure Sine Wave vs Modified Sine Wave: Which is better?
Pure Sine Wave is better and safer for electronics. It mimics the smooth electricity from your home outlet. Modified Sine Wave is cheaper but produces “choppy” power. This can cause buzzing in audio equipment and motors to run hotter. Choose Pure Sine for laptops and CPAP machines.
Conclusion
Selecting the right inverter depends on what you plan to plug in. For sensitive electronics and maximum efficiency, the Renogy 2000W Pure Sine Wave is our top recommendation. If you are powering tools and want a certified safe unit, the Krieger 2000W is an excellent heavy-duty alternative.
