Mkw Installed Capacity

UPower Series

Unite Capacity: 10kW / 40kWh x n + PCS (n=12~24)

Certifications: UL1973,CE

You can choose the number of units according to demand, matching with PCS to flexibly build systems of different sizes.

  • Highly integrated, small size, indoor/outdoor design
  • High-tech appearance
  • High reliability, high efficiency, maintenance-free

VPower Series

Unite Capacity: 500kW/2000kWh

(20GP Container x 2 + External Storage Tanks x 4 + PCS)

2 sets of containers and positive and negative storage tanks can be connected in series with a 500kW energy storage converter, constituting a 500kW/2000kWh ESS unit. You can construct different sizes of ESS flexibly based on that.

  • Separate design for power and capacity, energy storage duration customized as required
  • Suitable for building high power (above MW level) and large capacity (energy storage duration above 4 hours, 6 hours and 8 hours available)
  • Suitable for large-scale centralized ESS station construction
  • Highly integrated and space-saving

TPower Series

Unite Capacity: 500kW/2000kWh

(20GP Container x 4 + PCS)

4/5/6 units can be connected in series to an energy storage converter. For e.g. 4 units connecting a 500kW storage converter constitutes a 500kW/2000kWh unit ESS.

  • Containerized design, plug and play, easy and fast
  • No need for spacing between containers, effectively saving floor space
  • Standardized, modular design, easy system expansion

Intrinsic Safety

  • Inorganic water matrix electrolyte is non-flammable and non-explosive.
  • No risk of thermal runaway under normal temperature and pressure operation.
  • Good battery system consistency.
  • Efficient battery management and reliable operation.
Long Life
  • Working life of 25 years cycle charging and discharging
  • 16,000 times during the reaction process the electrode does not participate in the reaction
  • Deep charging and discharging does not affect battery life
0 Attenuation

On-line, low-cost capacity regeneration with 100% capacity retention and no efficiency degradation over the life cycle

Eco-friendly

The vanadium can be recycled with a mature reused recycling technology, no environment pollution

Smart Grid

Improve your power system’s economic performance

  • Manage the rapid growth of renewable energy sources
  • Alleviate the pressure on your grid’s stability and safety caused by large-scale integration
  • Optimize your grid’s structure and transmission capacity
  • Efficiently address issues such as wind and solar power curtailment.

Balance regional loads by shaving peaks and filling valleys, storing power during low periods and releasing it at peak times to improve the utilization of generating equipment.

Solve the short-time random power imbalance problem of the regional power grid, and improve the reliability and security of power grid operation.

When the grid is shut down due to a fault and cannot be restored by an external power source, a large-scale energy storage battery system can be used to realize a black-start.

Power Generation

Vanadium redox flow battery features safety, environmental friendliness, and a long lifespan, making it ideal for large-scale, long-duration energy storage on the power generation side. 

It effectively ensures the economic and stable operation of modern power systems with a focus on renewable energy sources.

  • Improve the acceptance capacity of the power grid for renewable energy power generation.
  • Participate in system peak shifting and frequency regulation, and improve power supply reliability and economic operation capability.
  • Cooperate with fossil energy power generation such as thermal power, and efficiently participate in frequency and peak regulation.

C&I ESS

vanadium redox batteries are also used in commercial and industrial energy storage to provide electricity economy and reliability.

  • Lower actual electricity expenses by utilizing off-peak electricity
  • Improve power supply quality and reliability as a backup power source
  • Reduce peak-to-valley load difference on the distribution network with a distributed generation and energy storage power supply system.

Product recommendation:
Upower Series – Flexible selection of several units according to needs
