Tilo brings colour into play. And chocolate to customers.

His paint tin says it in black and white: Tilo is “a reserved rock greige”. With customers, though, he brings colour into play. Our Sales Manager DACH Tilo Zwesper is touring all over Germany: from Berlin to Bavaria and down to us in the south. Because a conversation at the table is hard to beat, even in times of video calls.

And because a meeting simply tastes better with chocolate: anyone who arranges a visit will receive a Lindt chocolate basket.

What you can talk to Tilo about

• Your next project: which REFUsol inverters suit your plant, from commercial rooftops to solar parks, and how the REFUlink controls and monitors the plant.
• Repowering: how to replace old inverters. Until 18 December 2026 we deliver our C&I inverters free of charge in Germany and Austria. More about repowering
• Data security: who can access the control of your plant and where the data stays.
• Your existing REFUsol plants: questions about extension and operation. If there is a fault, our technical support will help you fastest.
