Solarbank Multisystem offers two key advantages over traditional residential PV and storage system. 

According to regulations, changes in PV installation capacity or grid-connected power require re-registration, while increasing only storage capacity does not.

Therefore, if you expand your solar panels of Solarbank after the initial installation, a qualified electrician must perform the re-registration. We recommend expanding both the solar panels and Solarbank at the same time to complete the registration in a single session.

If you are only expanding the storage capacity, such as adding a BP2700 battery pack, re-registration is not required.
