Inverter BMS Data Display

CAN Bus Battery Screen

The image below depicts the screen shown under “Settings > LI Batt Info” when

communications are enabled for CAN Bus batteries (“BMS Lithium Batt 00”).

1. Battery Voltage: Real-time voltage measured at the battery terminals.

2. Battery Current: Real-time current into (positive) or out of (negative) the battery.

3. Battery Temp: Real-time temperature measured at the BMS.

4. SOC: State of charge remaining in the battery according to the BMS.

5. SOH: State of health of the battery according to the BMS.

6. Battery Charge Voltage: Maximum voltage the inverter should charge the battery to.

7. Charge Current Limit: Maximum allowable current into the battery.

8. Discharge Current Limit: Maximum allowable current out of the battery.

9. Nominal_Cap: Amp-hour design capacity of the battery (not used on all batteries).

10. Alarms: Displays any alarm codes coming from the battery (manufacturer specific).

11. Force Charge Request: Command sent by the BMS telling the inverter to charge the

battery from any available power source regardless of inverter settings. Not shown on
