2.5MW 10kV Hybrid Solar Energy Storage Power Conversion System
The Voltertech BESS-25MW-W is a 2.5MW transformer-isolated power conversion unit for MW-scale hybrid solar and battery storage projects. It connects compatible 1000–1500V DC battery systems to a 10kV medium-voltage AC network and supports battery, EMS and plant dispatch communication.
For large solar-plus-storage plants, the battery system requires a power conversion stage that matches both the high-voltage DC battery architecture and the medium-voltage project network.
The BESS-25MW-W provides 2.5MW-class conversion capacity for projects where PV generation, battery storage and grid operation are coordinated through an EMS or plant-level control system.

The 2.5MW rating defines power conversion capacity, while the battery energy requirement is specified separately in MWh. This means two projects using the same 2.5MW PCS can require different battery capacities depending on the desired operating duration.
This separation between MW power and MWh energy capacity is important when configuring a solar-plus-storage system.
The AC side is rated at 2500kVA and 10kV, providing a medium-voltage interface for large hybrid solar and battery storage projects.
Transformer isolation is included in the electrical architecture. The specified power factor can be adjusted from -1 to +1, while AC total harmonic distortion is rated at no more than 3% at rated power.
A MW-scale hybrid solar system typically needs coordinated control between PV generation, battery storage, PCS and grid operation. The BESS-25MW-W provides communication interfaces for both battery-side control and project-level dispatch.
Final EMS and SCADA compatibility should be confirmed according to the project's control architecture.
The required battery capacity depends on the target storage duration and usable energy requirement. The PCS rating is 2.5MW, while battery capacity should be calculated separately in MWh for the specific project.
Yes. It can form the battery power conversion section of a compatible MW-scale PV + BESS system, working with the battery, EMS and other plant equipment according to the project design.
The specified DC operating range is 1000–1500V with a maximum current of 2619A. The battery system should be engineered so its operating voltage and current remain within these limits.
No. MW measures power, while MWh measures stored energy. A 2.5MW PCS can therefore be combined with different battery energy capacities depending on the required discharge duration and project strategy.
The AC interface is rated at 2500kVA and 10kV with transformer isolation. Final grid connection, protection and compliance requirements should be confirmed according to the project location and electrical design.
Provide the PV capacity, required charge and discharge power, battery MWh capacity or target duration, battery DC voltage, grid voltage, communication requirements, site temperature, altitude and project location.
Voltertech supports solar developers, EPC contractors and system integrators with MW-scale battery power conversion and energy storage solutions.
Send us your PV capacity, PCS power, battery MWh or target discharge duration, DC voltage and 10kV grid requirements so our team can evaluate the project configuration.
