Installing Kora with Supported Battery Systems

(Powerblocks, Powerwall, EcoFlow, etc.) Kora supports battery-backed systems by managing loads, backup behavior, and grid interaction. The battery system manages inversion and energy storage. Clear separation of responsibilities is critical.

Code Reference (NEC)

  • NEC 706 – Energy Storage Systems

  • NEC 705 – AC-coupled systems

  • NEC 480 – Storage Batteries (as applicable)

  • NEC 110 – Working clearances and ventilation

Supported Architectures

  • AC-coupled batteries (Tesla Powerwall, EcoFlow, etc.)

  • DC-coupled batteries via hybrid inverter (Powerblocks)

Kora interfaces on the AC side unless otherwise specified.

Key Installation Principles

  • Battery systems must be listed and approved per AHJ

  • Kora does not replace the inverter or battery BMS

  • Backup behavior is orchestrated by Kora using circuit priorities

Wiring and Installation Steps

  1. Install battery system per manufacturer instructions

  2. Land battery/inverter AC output at the designated breaker or input

  3. Size conductors per battery/inverter specs

  4. Install battery CTs if required

  5. Confirm neutral and grounding scheme compatibility

  6. Verify communication links where supported

  7. Configure backup priorities in app

Powerblocks-Specific Notes

  • Communication cabling required

  • Daisy-chain supported (up to 4 stacks)

  • Refer to Powerblocks manual for stacking limits

Commissioning Checklist

  • Battery visible and reporting correctly

  • Charge/discharge behavior confirmed

  • Backup mode tested successfully in app
