Home battery-storage installation before commissioning checklist

A pre-commissioning residential battery checklist for approved chemistry and capacity, indoor or outdoor location, fire and structural requirements, environmental and impact protection, working clearances, service and ventilation needs, conductors and disconnects, grounding, overcurrent and rapid-shutdown interactions, backup-load panel, solar and generator coordination, communications, internet and cybersecurity, utility approval, emergency labels, commissioning plan, warranty, and owner handover.

0%

Battery, inverter or gateway, capacity, chemistry, operating mode, and backup scope match approvals

Critical item

Installed equipment and intended whole-home or selected-load operation should be explicit.

Location, separation, fire protection, working space, structural support, weather, flood, and impact protection are complete

Critical item

The installation should comply with approved fire, building, electrical, and product location requirements.

Conductors, raceways, disconnects, grounding, overcurrent protection, backup panel, and source isolation are ready

Critical item

Multiple power sources should be clearly separated and safely controlled.

Solar, utility, generator, EV charging, HVAC, load management, and outage behavior are coordinated

Critical item

Control strategy should avoid overload, unsafe islanding, and conflicting sources.

Gateway, monitoring, firmware, internet dependence, administrator ownership, and cybersecurity are prepared

Critical item

The owner should control accounts and understand local and cloud operation.

Permits, utility approval, emergency labels, simulated outage, alarms, warranty, incentives, maintenance, and owner training are complete

Critical item

Commissioning should demonstrate charge, discharge, transfer, recovery, and fault-free operation before final payment.

Use after stationary storage equipment is installed but before commissioning and normal operation. Battery location and fire-code requirements vary, and utility involvement may be required. Do not remove electrical covers, operate unapproved equipment, test energized conductors, backfeed circuits, or bypass interlocks. Service, panel, EV, generator, solar, and battery work must be performed and inspected by qualified persons where required.
