Buzzing Squarewave!
Works well to a good price but:
1: Screws for covers too long so they
touch internal & may damage circuit board!
2: Nuts don't fit the DC connector bolts!
3: Loud buzzing noise when working due to Squarewave output!
4: Search function that should shut off when not in use
does not work well.
Conclusion:
A true sine-wave inverter is a better choice!
