PV and Storage Integration
Intelligent Power Distribution
The integrated power-sharing matrix controls multiple charging points in a way that makes optimal use of available grid capacity. No connection goes unused, and no threshold is exceeded.
Future-Proof System Architecture
FusionCharge scales from individual fast-charging stations to complex charging networks for fleets and public locations. New dispensers can be easily integrated into the existing system.
Centralized Monitoring & Operations Management
Charging processes, energy flows, and user data can be centrally managed via Huawei FusionCharge Management and OCPP-compatible third-party platforms. For operators, this means maximum transparency with minimal administrative effort.

Can the power unit be combined with photovoltaic systems or battery storage?
Yes. The DC bus architecture of the DS720-720LEUA4 enables direct coupling with AC-side energy storage systems. This allows the charging infrastructure to be seamlessly integrated into existing or newly planned PV and storage solutions.
How is the power unit managed and monitored?
How is the power unit managed and monitored?
The unit communicates with the Huawei FusionCharge Management system via 4G and Ethernet. In addition, a maintenance app for technicians and a user app are available via Wi-Fi, and the OCPP protocol is supported for integration with operator platforms.
What is the efficiency of the DS720-720LEUA4?
What is the efficiency of the DS720-720LEUA4?
At full load, the unit achieves an efficiency of 94.7%. Under optimal laboratory conditions, peak values of up to 95.5% were measured.
How loud is the power unit when it's running?
How loud is the power unit when it's running?
In standard mode, the noise level is a maximum of 60 dB at 25 °C. In mute mode, it drops to 55 dB—comparable to a quiet office conversation. This makes the unit suitable for use in nearby or urban environments.
What is the service life of the power unit?
What is the service life of the power unit?
Huawei specifies a projected service life of ten years. The theoretical module failure rate is less than 0.5%, which significantly reduces maintenance costs and unplanned downtime. In addition, neither the dirt-trapping mats need to be replaced nor does a fluid change need to be performed during the first ten years of operation.
