- Consumers must make informed choices depending on the complexity of their system and the level of functionality and ‘futureproofing’ they desire.
- Interoperability of DERs on-site and on-road becomes a greater issue for consumers when there is a need for grid integration.
- Where you live can have a big difference on the level of consumer choice, system value, and interoperability that is available. This is true even within countries like the United States.
- Over-the-air software updates are sold as a key feature of EVSEs, inverters, and batteries which could increase interoperability as new standards are released. It isn’t always clear to consumers where products will be updated or if hardware restrictions preclude this.
- Interoperability challenges vary considerably between devices and use-cases. Interoperability is less of an issue for solar-inverter or generation-only set-ups, but there are more challenges when incorporating EVSEs and batteries for storage or back-up power.
