No grid-tie/parallel supportTechnical Deep Dive: How F002 Outperforms
Installation Protocol
Wrong wiring order = Permanent damage
Step-by-Step:
- Connect P- → B- → NTC probes → Comm wires → Cell taps (B0→B20 sequentially)
- Secure all connectors with silicone glue (prevents oxidation)
- Never omit ESD protection during installation
Smart Power Management
| Mode | Trigger Condition | Power Consumption |
| Standby | No current/communication for 10s | <700μA |
| Shutdown | Cell voltage < threshold + no current | <20μA |
| Wake-up | Charging/discurrent/communication detected | - |
Port Definitions (Survival Guide)
| Port | Pinout | Function |
| B- | - | battery negative |
| P- | - | Charger/load negative |
| NTC | 4 channels | External probes |
| BT | GND/TX/RX/VDD | Bluetooth module |
| 485 | A/B/GND/VDD | RS485 communication (Baud: 9600) |
| H+/H- | - | Heating pad terminals |

Critical FAQs (Avoid Costly Mistakes!)
Q: Can I use F002 for grid-tied solar?
→ ❌ No. Supports off-grid only. Never parallel!
Q: How to configure sodium-ion batteries?
→ Share cell specs at order placement. We pre-burn firmware.
Q: Calibration trick for current sensing?
→ Use a 10A load to match APP/actual current by adjusting the shunt value.
