Need a Reliable Energy Storage Partner? SUNDTA Delivers – Right to Your Site!

SUNDTA, a leading provider of energy storage inverters and lithium battery systems, recently demonstrated its unwavering commitment to global customer support. Wink Zhang, Sales Director of SUNDTA, together with Li Xiaofeng, Operations and Maintenance Engineering Manager, traveled to Cuba for a hands-on technical visit at a local customer’s facility. Guided by the client, the team conducted a thorough on-site inspection of the customer’s energy storage system, which integrates SUNDTA’s storage inverters and wall-mounted lithium batteries.

During the visit, Li Xiaofeng meticulously analyzed and resolved several operational issues encountered by the customer. He also performed a comprehensive check of the system’s real-time performance, ensuring optimal functionality. This proactive, face-to-face support is a hallmark of SUNDTA’s service philosophy. The company regularly dispatches technical experts to overseas customer sites, offering both on-the-ground troubleshooting and dedicated 1-on-1 online technical support – a lifeline that guarantees minimal downtime and maximum efficiency for clients worldwide.

The following day, both parties convened for an in-depth technical discussion. Using SUNDTA’s 51.2V 280AH high-voltage rack-mounted lithium battery linked with an Atess energy storage inverter for power generation as a live case study, the teams explored synchronization protocols, load matching, and efficiency optimization. The discussion also paved the way for deeper collaboration in future projects, reinforcing SUNDTA’s role as a flexible and reliable partner in the global energy transition.
