Conductors
| Cable size | 4 AWG (25 mm²)[3] |
|---|
Protection
| Fuse or breaker | ADC isolator is recommended to be add on the power circuit between inverter and battery, recommended rating at 120Amps per set of external power cable[3] |
|---|
Grounding
| Grounding | Battery system must be well grounded and the resistance must be less than 4Ω[3] |
|---|
Communication
| Communication ports | RS232 communication port: (RJ11 port) comply with RS232 protocol (baud rate: 9600), for manufacturers or professional engineers debugging or service; CAN/RS485 communication port: (RJ45 port) follow CAN protocol and RS485 protocol, for output batteries information, the battery uses this interface to communicate with external inverters, PCS and other devices; Multi-device parallel connection: The two RJ45 ports are the same. Comply with RS485 protocol (baud rate: 9600), used for parallel communication between batteries[3] |
|---|---|
| Address / DIP setting | When the battery communicates with the inverter, the address of the battery pack must be set to 1, and the address of the parallel slave should be greater than 1[3] |
