Frequently Asked Questions
What can a 1000 watt Xantrex inverter run?
A 1000 watt inverter can comfortably run small household appliances. This includes laptops, televisions, gaming consoles, and small microwaves (under 800W cooking power). It can also handle small power tools like drills or sanders.
Do I need Pure Sine Wave or Modified Sine Wave?
For most modern electronics, Pure Sine Wave (like the Prowatt SW) is superior. It runs cooler and cleaner. Modified Sine Wave is cheaper and works fine for simple resistive loads like heaters or old incandescent lights. However, it may damage sensitive medical equipment or cause audio buzz.
What size fuse do I need for a 1000W inverter?
For a 12V 1000W inverter, the current draw can reach up to 100 amps or more during surges. We generally recommend a 150A ANL fuse installed close to the battery positive terminal to ensure safety.
Conclusion
Selecting the right Xantrex inverter depends on your specific power requirements. For the best balance of performance and protection for your electronics, the Xantrex Prowatt SW 1000 is our top recommendation. It offers clean power in a compact form factor. For those requiring a complete system overhaul, the Freedom X series provides professional-grade integration capabilities.
