Unreliable Inverter for Automotive Use

Based on my experience, this inverter is not reliable for use in an automotive setting. While it does have the ability to provide AC power from DC sources, it frequently shuts off and requires resetting. The one positive aspect is that it is relatively compact and easy to transport. However, the inconsistency of the device outweighs any convenience it may provide.

Pros
  • Efficient and reliable power converter that can be used for a variety of applications
Cons
  • May not be suitable for very high power applications

Not much 66% efficiency

Connect 3-315W solar panels with a 3-way splitter. And place them at an angle of 31° to the sun. It produces an average of 3.8 kWh per day from May to June. The peak of the day showed only 589 watts mains. This is below performance for the price. You can also hear the fans running about 20 feet away. The update no longer works after 5 months.

Pros
  • Creative MPPT technology, more than 99% efficiency, faster and more sensitive response, more reliable.
Cons
  • Reliable

QC is really bad. - Solar and wind energy

The quality control on these machines is a disgrace. I have bought 3 pieces in the last few months. The first had no manual or power cord. The second was a fire hazard: there was no plastic backing on the B+ and B- terminals INSIDE the unit. This would short out my panels if I didn't notice. The third block had a broken QC seal as well as 1 broken and 1 missing screw. Blocks work but only expect 70% efficiency.

Pros
  • Ideal electrical protection. Aluminum alloy body, anti-rust, heat-resistant and cold-resistant, as well as anti-corrosion.
Cons
  • I don't have much aversion to it, everything is fine
