Case Study: DASS Tech achieves over 1000% reduction in maintenance costs with TeamViewer

DASS Tech solved issue of remote monitoring with TeamViewer

DASS Tech, Korea’s leading photovoltaic inverter manufacturer operating about 500 unattended solar sites, needed a way to monitor inverter status across remote southern regions without costly field visits. Routine inspections required around 10 hours and KRW 300,000 per trip from their head office, creating pressure to cut maintenance costs and improve customer satisfaction.

By deploying TeamViewer on remote terminals, DASS Tech can instantly check device and internet status, perform remote fixes, and coordinate support without onsite visits. Inspections dropped from 10 hours to 10 minutes and costs fell from KRW 300,000 to KRW 500, yielding more than a 1000% decrease in maintenance costs, faster fault resolution, higher customer satisfaction, and an estimated ROI on licenses within one month.
