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.
