Layered safety

Ten protections, on continuous watch.

Safety isn’t an add-on. It’s built into every layer of the system, from the BMS to the grid connection, to protect your home and your install.

  • Arc-fault detection (AFCI)
  • AC surge protection, Type II
  • PV surge protection, Type II
  • Active fire prevention
  • Insulation monitoring
  • Anti-islanding protection
  • Overload & short-circuit protection
  • BMS thermal management
  • Overvoltage / undervoltage protection
  • Emergency shutdown (rapid shutdown)

Whole-home energy control

Intelligent control, in service of your savings.

The system automatically optimizes your energy flows based on uses, tariffs, and weather. You produce, store, and consume at the right time, without thinking about it.
