Battery System Installation Guide

Installation guide for battery systems including NEC code references, supported architectures such as Tesla Powerwall and Powerblocks, wiring procedures, and commissioning checklist.

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

Install battery system per manufacturer instructions
Land battery/inverter AC output at the designated breaker or input
Size conductors per battery/inverter specs
Install battery CTs if required
Confirm neutral and grounding scheme compatibility
Verify communication links where supported
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

Commissioning
