Episode notes
Modular AC-Coupled System Design
- Enphase's AC-coupled architecture lets solar, battery, EV charger, and software evolve independently while remaining integrated.
- This enables future-proof upgrades and incremental additions without replacing existing components.
Consolidate Hardware With A Combiner
- Use the new combiner and embedded load controls to simplify installations and reduce wall clutter.
- Eliminate separate system controllers to lower installation time and failure points.
CTs Move Into Distributed Components
- Enphase removes external CT wiring by embedding production and battery CTs inside the combiner and consumption CTs in the meter collar.
- Distributed CTs on EV chargers and load controls provide accurate, localized load awareness.
