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.

Battery CabinetStores energy through 166V314Ah LiFePO4 liquid-cooled cabinet modules in 156kWh–522kWh configurations.
Liquid CoolingLiquid cooling and automatic coolant replenishment should be reviewed together with site temperature, maintenance access and cabinet duty cycle.
PCSSelected separately according to DC voltage range, battery current limit, system power and communication protocol.
PV / GridPV input, grid connection and AC-side configuration should be confirmed according to project electrical architecture.
GeneratorDiesel generator integration can be reviewed when backup operation or weak-grid operation is required.
LoadsCritical and normal loads should be separated according to backup duration, load priority and site operation requirements.
Final system design depends on PCS voltage range, BMS protocol, electrical protection, liquid-cooling maintenance plan, site exposure, foundation design, load priority and target market requirements. Compatibility should be confirmed before order confirmation.

Why This Battery Cabinet Is Selected

Advantage 01

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.

Advantage 02

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.

Advantage 03

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.

Advantage 04

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.

Advantage 05

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.

Advantage 06

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.

FAQ

Which project data should be reviewed before selecting the AINEGY 166V314Ah IP65 liquid-cooled battery cabinet?Review the required usable capacity, backup duration, PCS power, PCS DC voltage range, maximum charge and discharge current, BMS communication protocol, installation environment, duty cycle, target market and documentation requirements before selecting the cabinet configuration.
How should the 156kWh, 209kWh, 261kWh and 522kWh configurations be matched with PCS voltage range?Match the cabinet nominal voltage and full voltage window with the PCS DC input range. The 156kWh configuration is 499.2V nominal, the 209kWh configuration is 665.6V nominal, and both 261kWh and 522kWh configurations are 832V nominal. The full charge and discharge voltage limits must be checked before order confirmation.
When should the 522kWh 5S2P configuration be selected?Select the 522kWh configuration when higher energy capacity is required while maintaining an 832V nominal battery platform. The 5S2P arrangement should be checked against PCS current capacity, protection settings, DC cable design, cabinet footprint, foundation load and lifting conditions.
Which charge and discharge current limits must be confirmed with the PCS?Confirm 100A standard charge current, 150A maximum charge current, 100A standard discharge current, 200A maximum discharge current and 250A peak current against the selected PCS, DC protection devices, cable sizing and battery operating strategy.
What liquid-cooling maintenance conditions should be reviewed for this cabinet?Review coolant service access, automatic coolant replenishment expectation, cabinet duty cycle, ambient temperature, maintenance clearance, local service capability and whether the site can support routine inspection of the liquid-cooling system.
What installation checks are required for the IP65 battery cabinet?Check indoor, semi-outdoor or outdoor installation conditions, drainage, cable entry, dust and water exposure, humidity, altitude, cabinet spacing, foundation load, delivery path, lifting plan and maintenance access. IP65 does not mean immersion, flood exposure or high-pressure washdown suitability.
Which system components are outside the scope of this battery cabinet?This product is the DC-side LiFePO4 battery cabinet. PCS, transformer, PV inverter, grid connection equipment, generator interface, AC distribution, protection coordination and site civil works should be selected and designed at system level.
What commercial and documentation information should be prepared before quotation review?Prepare destination country, required certificates, selected model, project quantity, delivery location, project schedule, customization scope, branding requirements, target application and any documentation needed for tender submission, grid approval or system integration review.
