Founded in 2004 by a forward-thinking team of German and Chinese engineers, TGOOD is the world leader in eHouse solutions and the world's largest EV charging infrastructure provider today. We manufacture all eHouse and electrical components in-house.

We measure delivery and installation time in weeks, not months

Faster Installation
