Selection Notes
- Match 499.2V / 665.6V / 832V nominal voltage with the PCS DC input range.
- Check the full battery voltage window: 436.8–561.6V, 582.4–748.8V or 728–936V.
- Review PCS charging power using 100A standard charge and 150A maximum charge current.
- Review discharge design using 100A standard discharge, 200A maximum discharge and 250A peak current.
- Use cabinet size and weight to confirm foundation, lifting plan, delivery path and installation clearance.
Product Boundary
- Battery cabinet on the DC battery side.
- PCS, transformer, PV inverter, AC distribution and site civil works are not included by default.
- IP65 refers to battery cabinet enclosure protection; immersion, flood exposure and high-pressure washdown should not be assumed.
Configuration Logic
- Each 166V314Ah module is about 52kWh at nominal voltage.
- 3 / 4 / 5 modules build the 156kWh, 209kWh and 261kWh configurations.
- The 522kWh cabinet uses 10 modules arranged as 5S2P, keeping 832V nominal voltage while increasing energy capacity.
- RS485 / CAN communication should be checked with the selected PCS before order confirmation.
System Design & Energy Storage Integration
This liquid-cooled battery cabinet is the DC-side battery section of a C&I energy storage system. It is typically matched with a compatible PCS, while PV input, grid connection, generator backup and site loads are designed at system level.
Why This Battery Cabinet Is Selected
Liquid-Cooled Platform for Larger C&I ESS Cabinets
This product covers 156kWh, 209kWh, 261kWh and 522kWh configurations in one liquid-cooled cabinet family, making it suitable for commercial and industrial projects requiring higher battery capacity than compact air-cooled cabinet classes.
522kWh Configuration Without Raising Nominal Voltage
The 522kWh version uses a 5S2P arrangement. This keeps the nominal voltage at 832V, the same voltage level as the 261kWh configuration, while increasing energy capacity through parallel module grouping.
High-Voltage PCS Matching Range
The 499.2V, 665.6V and 832V nominal voltage options provide a practical matching range for high-voltage PCS-based C&I ESS designs. The full voltage window should be confirmed before PCS selection.
Integrated Automatic Coolant Replenishment
The integrated automatic coolant replenishment system supports liquid-cooling operation and helps project teams plan coolant management at cabinet level. It should still be reviewed with service access and maintenance procedures.
IP65 Battery Cabinet Protection
IP65 battery cabinet protection is suitable for projects where dust and water-jet exposure must be considered. Final installation still needs site review for drainage, cable entry, foundation, ventilation and local environmental conditions.
Clear Current Boundary for PCS Design
The 100A standard charge / discharge current, 150A maximum charge current, 200A maximum discharge current and 250A peak current provide clear boundaries for PCS power, protection settings and DC cable design review.
Typical Applications
This 156kWh–522kWh IP65 liquid-cooled battery cabinet is mainly selected for C&I ESS projects where higher battery capacity, liquid cooling, cabinet protection level and PCS matching must be reviewed together.
Certification and Documentation Support
AINEGY products are designed and manufactured with reference to relevant international safety, transport, electrical and material standards. Certification documents are available for certified models, and project-specific certification requirements can be reviewed according to the selected model, configuration and target market.
