How to reset Comms at 100% SOC

Modified on Wed, 28 Aug at 3:13 PM

Resetting SOC

Firstly, start with increasing your battery parameters with increments of 0.2V until you reach 100%.

The three stages are:

1) Bulk/Equalized charge (current control) -used for fast charging when the SOC is low

2) Absorb charge (voltage control) -used to prevent over- charging the battery when the SOC is higher than a certain level

3) Float charge (voltage control) -used when the battery is close to fully charged.

Diagnosing The Problem

Please check all the batteries are at the same level of charge and the dip switch settings are correct. If the batteries are not at the same SOC please charge each battery up individually as described below. If the batteries are at the same voltage and dip switches done correctly you may leave the batteries connected in parallel.

Proceed with the following instructions:

1) Disconnect the CAN comms cable.

2) Change the battery type on the inverter to AGM V.

3) Please input the Float, Bulk and Equalization Voltage at 53,6Vdc (AM2 & X-101).

4) Please set the Low Voltage to 44Vdc.

5) Charge up battery until the inverter stops charging the battery to 53.8Vdc, this may take some time as the BMS will do a cell balance at full voltage.

6) Once the inverter has stopped charging, reconnect your CAN cable and go back into your inverter battery menu and activate the Lithium settings and CAN communications.

Please note that no discharging is needed for this issue to be resolved.
