EG4 Configuration Notes¶
- Inverter must be configured for correct battery type (LFP, not lead-acid)
- BMS communication cable must be connected between inverter and first battery
- Multiple batteries in parallel require correct bus bar configuration
- Charge voltage cutoff: ~58.4V (do not exceed)
- Low voltage cutoff: ~44V (do not go below)
Check Inverter Settings
Incorrect charge voltage settings on a non-EG4 inverter connected to EG4 batteries can cause overcharge or communication failure. Always verify inverter settings match the battery specification.
EG4 Monitoring¶
- Local: inverter display panel
- Remote: EG4 app (iOS/Android) via Wi-Fi
- Data includes: SOC, voltage, current, temperature, cycle count
