5MWh Liquid-Cooled Hybrid Solar Battery Energy Storage System
The Voltertech BESS-5MWH-W is a high-voltage 5MWh LiFePO4 battery container designed for large hybrid solar and solar-plus-storage projects. It provides high-capacity DC energy storage that can be integrated with compatible PV, PCS and EMS equipment according to project power, discharge duration and grid requirements.
Large photovoltaic plants do not always produce energy at the same time it is required by the grid or local loads. Adding battery storage allows part of the available solar generation to be stored and dispatched according to the project's operating strategy.
The BESS-5MWH-W acts as the high-capacity battery block within this architecture and can be combined with suitable power conversion and energy management equipment.

In a hybrid solar architecture, PV generation, battery storage, PCS and EMS are coordinated according to the required operating strategy. The battery can store available electrical energy and release it during selected periods when the project requires additional flexibility.
A 5MWh battery rating describes energy capacity, not the AC power output of the complete system. The required PCS power should therefore be selected according to the project's desired MW rating and operating duration.
For example, projects with different discharge-duration targets may use different PCS configurations even when the battery capacity remains 5MWh. Final sizing should consider PV capacity, grid connection, duty cycle and usable energy requirements.
Liquid cooling manages battery temperature across the container during charging and discharging. For a high-capacity battery block, stable thermal management is important for maintaining consistent operation across battery modules.
The system also supports LAN, RS485 and CAN communication for connection with compatible monitoring, PCS and energy management platforms.
5MWh refers to the amount of electrical energy the battery system can store. It does not by itself define the system's MW power output, which depends on the selected PCS and project design.
PCS power should be selected according to the required MW output, discharge duration, grid connection and operating strategy. The BESS-5MWH-W is supplied with PCS as an optional project configuration.
Yes. It can be integrated into compatible large PV and solar-plus-storage projects. The complete design should coordinate PV capacity, battery storage, PCS, EMS and grid requirements.
Yes. Battery energy capacity and system power are separate design parameters. Different PCS ratings and operating strategies can result in different discharge durations for a 5MWh battery system.
Large hybrid projects commonly use an energy management system to coordinate PV generation, battery charging and discharging, PCS operation and project-level energy dispatch. The required control architecture should be confirmed during system design.
Provide the PV capacity, required PCS power, target discharge duration, grid voltage and frequency, project location, operating strategy and whether PCS and EMS are required. These details allow the battery and power configuration to be evaluated correctly.
Voltertech provides high-voltage battery storage solutions for solar developers, EPC contractors and energy system integrators.
Send us your PV capacity, required MW power, discharge duration, grid conditions and project location so our team can evaluate a suitable BESS configuration.
