3-phase Hybrids-FAQ

Replacement or expansion of residential energy

storage battery module

Applicable to: SBR HV Batteries

Scenario:

1. If the customer needs to add more battery modules (for example, add two

battery modules to an existing SBR096).

2. If one battery module is faulty and new battery module needs to be

replaced.

3. If two battery modules need to be removed.

Solution:

For scenarios 1 and 2, the battery modules in use need to be charged or discharged

to SOC of the new battery. New battery’s SOC can be estimated with knowing

manufacturing date and storage time. (see below table)

Assume for example that the SOC of the new battery module is 20%, and the

battery on user site is 70%, please proceed as follows:

Select Compulsory Mode in the Energy Management Parameters and set Charge

as a charging command.

Apply the settings.

Set the SOC Upper Limit to 100% and the SOC Lower Limit to 20 % (calculated

value for the new battery). Apply the settings. By charging the battery to 100%, a

calibration is performed to improve the accuracy of SOC.

(This takes some time, can be omitted and the target SOC value can be directly set

and charged or discharged to the target SOC.)

After charging to 100%, select discharge and Apply the settings. The battery will

automatically discharge to 20% and stop.

Now the battery SOC on user site is the same as SOC of the new battery module

20%, so the installer can install the new battery module.

After replacement, stop Compulsory mode and reset Upper and Lower SOC Limit

to its original values. (default: SOC upper limit 100%, SOC lower limit 10%

For scenario 3, we can remove two modules directly, because the power of the five

modules is the same. If we remove two battery modules, the remaining three

battery modules will also work normally.
