3.44MWh Liquid Cooling Hybrid Solar Battery Energy Storage System
The Voltertech BESS-3.44MWH-W is a high-voltage 3.44MWh LiFePO4 battery storage container designed for integration into large hybrid solar and solar-plus-storage projects. Its liquid cooling system, outdoor container design and flexible PCS configuration make it suitable for utility PV plants, microgrids and large renewable energy projects.
Large solar projects often need battery storage to shift available PV energy to different operating periods and provide greater flexibility between solar generation, battery charging and grid demand.
The BESS-3.44MWH-W provides a containerized DC battery platform that can be integrated with compatible PCS, EMS and photovoltaic equipment according to the project's electrical architecture.

In a hybrid solar project, the battery container works as the energy storage section of the overall system. It can be combined with solar PV, compatible PCS equipment and an energy management system to control charging and discharging according to project requirements.
High-capacity battery containers require stable temperature management across the battery system. Liquid cooling helps maintain more consistent operating temperatures and supports long-term battery performance during repeated charging and discharging.
The 3.44MWh container also provides LAN, RS485 and CAN communication interfaces for integration with compatible monitoring, PCS and energy management equipment.
The battery container stores electrical energy within a larger PV and energy storage system. It can be integrated with compatible PCS and EMS equipment to manage charging, discharging and solar energy utilization according to the project design.
PCS is optional for this model. The required PCS configuration should be selected according to the desired charge and discharge power, PV capacity, grid connection and operating strategy.
Yes. The BESS-3.44MWH-W is suitable for integration into compatible utility-scale and large commercial PV projects. The electrical interface, PCS, EMS and protection design should be confirmed for each project.
3.44MWh describes the battery energy capacity, not the AC output power. Because PCS is optional, the final kW or MW power rating depends on the selected PCS and the required charge or discharge duration.
Liquid cooling provides controlled thermal management across a large battery system and helps maintain more consistent battery temperatures during charging and discharging.
Useful project information includes PV capacity, required BESS power, expected charge and discharge duration, grid voltage and frequency, site conditions, operating strategy and whether PCS and EMS are required.
Voltertech supports EPC contractors, solar developers and system integrators with large-scale LiFePO4 battery storage solutions.
Send us your PV capacity, required battery power, discharge duration, grid information and project location so our team can evaluate a suitable BESS configuration.
