One proposal adds storage but leaves the existing solar inverter's monitoring and support unspecified.
THE BRIGHTON & HOVE FIELD GUIDE / HOME BATTERIES
Home battery installers in Brighton & Hove
Adding storage to existing solar creates a support boundary. Ask a Brighton & Hove installer who diagnoses faults across the two systems.

START WITH THE PROPERTY
Draw the system as it will be wired
If Brighton & Hove solar is already installed, send inverter and monitoring details plus photographs of possible battery locations. The storage decision includes how new controls will communicate with old equipment.
BEFORE YOU ACCEPT A QUOTE
Do not buy capacity in isolation
The quotation should show usable storage, connection method, siting and any change to the existing warranty or monitoring. Ask who supports faults that cross the boundary between old and new components.
ILLUSTRATIVE QUOTE COMPARISON
Who fixes a fault across old and new equipment?
Another identifies the control interface and which installer owns diagnosis.
Get the connection diagram, warranties and support boundary in writing. A battery that charges today still needs a clear fault path tomorrow.

Ask what the battery will do daily.
Once integration is understood, compare usable capacity against the home's evening demand and export. The most compatible unit is not automatically the most valuable size.
