Description

Sunwoda OASIS Flex — is a scalable modular solution for the commercial and industrial sector, created for the efficient management of energy costs, ensuring autonomy and increasing the energy independence of a business.

Key economic and technical objectives

  • Cost optimisation: Reduction of electricity payments through tariff arbitrage (charging during the night period, discharging during the peak period).

  • Peak smoothing (Peak Shaving): Shaving peak loads to prevent exceeding the permitted power limits.

  • Backup power: Ensuring the uninterrupted operation of critical infrastructure during emergency grid outages.

  • Energy independence: Storing generation from own renewable sources (solar power plants) to maximise self-consumption (Self-Consumption).

Architecture and scaling

  • Modular design: Makes it possible to select the initial capacity and power flexibly for the specific load profile of a facility.

  • High scalability: Supports the parallel combination of up to 6 clusters, which ensures expansion of the system as the needs of the enterprise grow.

Application areas

The system is developed for facilities with a high level of energy consumption and strict requirements for power supply reliability:

  • Industry: Manufacturing enterprises, factories, workshops.

  • Logistics and retail: Warehouse complexes, distribution centres, shopping malls.

  • Property development: Office centres, business complexes, hotels.

  • Agricultural sector: Grain elevators, processing complexes, farms.
