Selection Notes
- Match nominal voltage and voltage window with PCS DC input range.
- Use charge / discharge current to check PCS power configuration.
- Use size and weight to confirm delivery, lifting and installation access.
Product Boundary
- Battery rack only.
- PCS, transformer, PV inverter and outdoor enclosure are not included by default.
- IP20 is for indoor or protected installation, not direct outdoor exposure.
Configuration Logic
- 7 / 8 / 13 / 15 module configurations provide different capacity and voltage levels.
- RS485 / CAN communication should be checked with the selected PCS before order confirmation.
System Design & Energy Storage Integration
This AINEGY battery rack is the DC-side battery section of a C&I energy storage system. It is typically connected to a compatible PCS, while PV input, grid connection, generator backup and site loads are designed at system level.
Why This 51.2V314Ah Battery Rack Is Selected
High-Voltage Platform for PCS-Based C&I ESS
With 358V, 409V, 665V and 768V configurations, this AINEGY rack is intended for high-voltage PCS-based commercial energy storage systems rather than low-voltage residential battery applications.
One Module Platform, Multiple System Sizes
The AINEGY 51.2V314Ah module platform supports 112kWh to 241kWh configurations by adjusting module quantity, which helps system integrators select capacity and voltage within one product family.
Suitable for Projects with Separate PCS Design
This AINEGY product is useful when the project already has a selected PCS, electrical room, AC distribution design or system integration plan, and only the battery rack section needs to be matched.
Indoor IP20 Design with Clear Application Boundary
IP20 is suitable for indoor or protected ESS rooms. This avoids presenting the product as an outdoor cabinet and helps customers select the correct protection level for the project site.
Air Cooling for Protected Installation Rooms
For indoor C&I ESS rooms with suitable ventilation and moderate system density, air cooling provides a direct thermal design without liquid-cooling pipework or coolant management.
Detachable Rack Design for Project Handling
The detachable rack structure supports packaging, transportation, installation and maintenance planning for project deployment.
Typical Applications
The AINEGY 51.2V314Ah battery rack is mainly selected for indoor C&I ESS projects where battery capacity, PCS matching and system integration flexibility are required.
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.
