Sunsynk Smart Storage Secures VDE-4110 Certification for Its SUNSYNK 30–50 kW Hybrid Inverters
Singapore, 14 October 2025
Sunsynk Smart Storage Pte Ltd is delighted to announce that its SUNSYNK 30–50 kW hybrid inverters have successfully achieved VDE-AR-N 4110 certification, marking a significant milestone for the company and its European customers.
“This certification opens up tremendous opportunities, particularly in the German market, where grid-connection standards are among the most stringent in the world,” said Jan Kemeling, Founder and Co-Owner of Sunsynk Smart Storage. “Our customers in Germany have been eagerly awaiting this moment. With VDE-4110 approval now in place, they can confidently connect our hybrid inverters to medium-voltage networks operated by German grid providers.”
For larger-scale projects in Germany—and in other regions governed by similar grid-code standards—VDE-4110 certification is both a competitive advantage and, in many cases, a prerequisite. It provides assurance to grid operators and regulators that the equipment fully meets the technical and safety requirements for integration into medium-voltage networks.
T. T. Lim, Co-Owner of Sunsynk Smart Storage, added:
“Our market share in Germany continues to expand. By focusing on industrial applications and medium-voltage systems, we help our clients accelerate their return on investment through intelligent, connected energy-storage solutions.”
Kemeling further elaborated:
“This certification enables our customers to explore advanced business models—such as participating in energy-imbalance trading with large-scale battery systems, or operating EV-truck charging facilities at factories and distribution centers. These additional revenue streams make BESS investments highly attractive, even for companies whose core operations lie outside the energy sector.”
About VDE-AR-N 4110 Certification
VDE-AR-N 4110 is the German Technical Connection Rule (TCR) governing connections to medium-voltage networks. It defines the requirements for integrating generation and storage systems—including hybrid inverters—into the grid.
Inverters certified under this standard are verified to:
• Operate reliably within medium-voltage networks under both normal and fault conditions (including voltage dips and frequency deviations).
• Provide reactive-power control and voltage-stabilisation capabilities within prescribed limits.
• Meet protection and disconnection parameters (over-/under voltage, over-/under frequency, etc.).
• Maintain high power quality by limiting harmonics and flicker.
• Support fault-ride-through and data-logging functionalities, enabling transparent and auditable grid interaction.
Certification applies to specific inverter models and configurations and confirms tested compliance. It is generally time-bound and subject to periodic re-validation.
