Great company that does the work done as promised – timely and reliably.

We have searched for a place to repair the inverters and shipped them to various companies to no avail. El-Tech Lab proved time and time again to be the best company in the country to do the job. Over dozen original inverters failed, none of the repaired one over past 4 years!

Felix finds the way to do the quality repairs! Highly recommended!
