Yes, you can retrofit battery storage to your current solar PV system. The complexity of this addition depends on the initial setup of your solar PV system. For Systems Designed for Future Expansion: If your solar panels were installed with future storage in mind, integrating battery storage is typically straightforward. In such cases, the inverter is already compatible with power storage requirements. For Systems Without Initial Storage Design: If your solar panel system wasn’t initially designed for battery storage, there are several viable options: Inverter Replacement: Swap your current inverter for one compatible with battery storage. Adding a Storage Inverter: Install a storage inverter alongside your existing inverter. Inverter-Integrated Batteries: Opt for battery storage units with built-in inverters, allowing for the removal of the old inverter and seamless integration.
