Active engineering prototype

QD5060 — Critical-Load Battery Backup Platform

A 48 V LiFePO₄ engineering prototype for critical household loads, combining cloud-independent safety control with secure web and mobile monitoring.

Challenge

Maintain selected critical loads during outages while keeping safety decisions local.

Constraints

Longer appliance-runtime testing remains open; not certified, production-ready, whole-home, or universally seamless.

System

Embedded safety controller, dedicated device bridge, mutually authenticated messaging, and supervisory web/mobile applications.

Magneum’s contribution

Core transfer, charging, monitoring, and supervisory architecture demonstrated.

Verification

A loaded wall-power cut kept the witness lamp lit for roughly 75 seconds while the battery handled repeated high-load bursts.

Outcome

Core transfer, charging, monitoring, and supervisory architecture demonstrated.

Limitations

Longer appliance-runtime testing remains open; not certified, production-ready, whole-home, or universally seamless.
