HARDWARE SPECIFICATIONS
JK-B2A24S30P data by hardware revision
The V19.0.2 manual verifies chemistry-specific 7-24S/8-24S/14-24S limits, 300 A maximum charge and discharge current, 2 A active balancing, operating limits and mechanical data. Wired communication remains configuration-dependent.

- CAN and RS485 are optional and must be present in the ordered configuration.
- A physical CAN or RS485 port does not by itself confirm inverter protocol compatibility.

Revision control matters.
- V19.0.2 is the newest applicable revision located in the verified package; this does not by itself prove the current shipment revision.
- Confirm the shipped label and communication suffix before using the manual's connector definitions.
Before ordering
Four details that prevent the wrong configuration
- Confirm battery chemistry and exact series count.
- Confirm the expected charge/discharge duty, cable size, terminals, fuse and cooling.
- State whether CAN, RS485, heating, alarm, parallel interface or ACC is required.
- Provide the inverter brand/model and confirm protocol, firmware, cable and pinout before shipment.
