3.44MWh Liquid Cooling LiFePO4 Hybrid Solar Battery Energy Storage System for Large Projects
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.
3.44MWh Battery Storage for Hybrid Solar 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.

Frequently Asked Questions
1. How is a 3.44MWh BESS used in a hybrid solar system?
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.
2. Does the 3.44MWh system include a PCS?
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.
3. Can this BESS be integrated with a solar power plant?
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.
4. What is the power output of a 3.44MWh battery system?
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.
5. Why is liquid cooling used for this battery container?
Liquid cooling provides controlled thermal management across a large battery system and helps maintain more consistent battery temperatures during charging and discharging.
6. What information is needed to configure a hybrid solar project?
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.
