4. Integration & Standards Roadmap (Cross-Platform)

Across all major product lines above, roadmap work will focus on:

Standardised package templates: Pre-defined panel, inverter, battery, and EV charger combinations for typical load profiles (small, standard, high consumption, and multiple EVs).

Blackout/backup options clarity: Precise mapping of which products support full-home versus partial-circuit backup, along with the required gateways/switchgear.

VPP & tariff optimisation readiness: Prioritise platforms with strong VPP capability (e.g., Fox ESS, Tesla, others, where applicable).

Technical documentation alignment: Consistent datasheet links, one-click downloads, and uniform formatting across all panel and storage families.
