Sunwoda OASIS A200 All-in-One Energy Storage System

Sunwoda OASIS A200 All-in-One — is a ready-made, highly integrated commercial- and industrial-class energy storage system (AC-coupled). Unlike the basic DC model OASIS A200, the version All-in-One combines in a single Outdoor enclosure the battery block (200 kWh), the power inverter (PCS) and the climate control, fire suppression and intelligent management (EMS) systems. This is a comprehensive “Plug & Play” solution that is connected directly to the alternating current network of the enterprise without the need for external inverter equipment.

Key difference: OASIS A200 vs OASIS A200 All-in-One

• OASIS A200 (DC version): This is exclusively a battery cabinet, which requires the mandatory selection and installation of a separate external inverter (PCS).

• OASIS A200 All-in-One (AC version): A fully self-contained complex with a built-in bidirectional converter (PCS). Thanks to the alternating current output (380/400 V), the system is ready for operation immediately after connection to the power switchboard of the facility, which substantially reduces design costs, the installation footprint and the installation work.

Main objectives and functional capabilities

• Tariff arbitrage (Time-of-Use): Automatic charging from the grid during the off-peak (night) period and discharging during the most expensive daytime tariffs.

• Peak load shaving (Peak Shaving): Instant coverage of consumption surges to prevent penalties for exceeding the permitted power limits.

• Full UPS function: An uninterrupted power supply to critical process lines and equipment during emergency outages of the main grid.

• Maximisation of self-consumption (Self-Consumption): Efficient storage of surpluses from industrial solar power plants (SPP) for the enterprise's own needs.

Compatibility and advantages of the All-in-One architecture

• Direct AC connection: Integrates easily into the existing electrical network of an enterprise in parallel with any third-party grid-tie solar inverters.

• Compact design: Thanks to the integration of the inverter into a common IP55 enclosure, the system occupies a minimal area at the facility and is intended for outdoor (Outdoor) installation next to a transformer substation or a workshop.

• Factory readiness: Does not require complex matching of protocols between the battery and a third-party inverter — the internal BMS and EMS work as a single coordinated organism.

Application areas

Ideally suited to facilities that require the rapid turnkey deployment of a storage system with a minimal occupied area:

• Industry and workshops: Protection of continuous production processes against voltage surges and outages.

• Warehouse and logistics complexes: Optimisation of energy requirements and ensuring the operation of refrigeration units.

• Commercial real estate: Shopping and entertainment centres (malls), business centres, hotel complexes.

• Critical infrastructure: Water supply facilities, data centres (data processing centres), medical institutions and charging complexes (EV Charging Hubs).
