We specialize in repairing your saws three phase high power inverters.


You can save from 50% to 70% on having your power inverter repaired and protect your valuable investments, with us. Here are some good reasons why you should send your Inverter to us for repair and maintenance, rather than to local repair shops and the manufacturer. SperryTek is experienced and familiar with these models. Our technicians can troubleshoot directly to the problem. We can also detect the worn out and nearly defective parts that cause most of the intermittent problems, in which most services shops cannot find out. So you can get your inverter fixed right, the first time, and avoid damages by inexperience technicians trying to explore. Your power inverter will be thoroughly inspected as we work on it. While your equipment is in our repair center, we will keep you informed and involved. Only appropriate and necessary repairs will be performed. After your power inverter is repaired we perform a full dynamic load test on it to make sure it will be in perfect working order under the most stressful of conditions. The repair isn’t complete until you’re satisfied.
