ESTG visiting SMA Solar Technology! ☀️🔋

On May 19 and 20, we had the privilege of visiting .solar headquarters in Kassel, Germany. It was an intensive and inspiring two days focused entirely on smart developments, reliability, and strategic collaboration.

Day 1: We kicked off the trip with an exclusive and impressive tour of SMA’s various production and testing facilities. It was great to see firsthand how their inverters and batteries are manufactured and tested with the highest precision and using the latest techniques. After a day filled with technical insights, we spent a wonderful evening enjoying dinner at a beautiful location in Kassel.

Day 2: Today, the doors were wide open to the future. During a series of in-depth presentations, we received an exclusive update on the upcoming product portfolio and SMA’s strategic approach for the coming years. This looks incredibly promising for putting SMA strongly back on the map! Armed with this valuable knowledge, we can support our installers across Europe even better with the right SMA solutions.

Our compliments to the SMA team for the professional organization and warm hospitality. Everything was perfectly arranged down to the last detail! Here’s to a great, sustainable future together. 🤝✨
