Savant Power System & Smart Companion Modules: Luxury Microgrid Automation

Engineered for luxury custom homes, 400A–800A estates, and multi-panel microgrids, the Savant Power System uses snap-in dual-circuit companion modules inside standard Square D QO or Eaton BR panels to orchestrate solar, multi-stack LFP batteries, and standby generators with millisecond precision.

Key Master Electrician & ROI Takeaways

  • ✓Scales effortlessly across 2, 3, or 4 subpanels (400A to 800A services) where single-box smart panels hit a hard ceiling.
  • ✓Snap-in Power Modules occupy standard 1-inch or 3/4-inch breaker spaces alongside existing breakers and switch up to 60A at 240V.
  • ✓Deep integration with Savant home automation scenes—pressing 'Storm Mode' or 'Eco Mode' adjusts lighting, HVAC setpoints, and circuit relays simultaneously.
  • ✓Native Sol-Ark and Savant Power Storage 20 integration manages generator auto-start and dynamic phase balancing.

Single-Line Wiring & NEC Topology

Multi-Panel Estate Microgrid with Companion Relay Modules
Upstream Utility / MID Connection
Supports parallel 200A panels (400A service) or 400A/600A commercial CT cabinets.
Solar & Battery Inverter Landing
Pairs with Savant Power Storage 20 (12.5kW / 20kWh LFP units stackable to 100kWh) or Sol-Ark 15K parallel stacks.
Neutral-Ground Bonding (NEC 250)
Uses standard load centers—preserves native NEC 250 service entrance or subpanel bonding.
Hardware Fail-Safe Behavior
Physical manual override switch on every Savant Power Module face allows manual circuit energizing independent of controller.

Engineering Pros

  • +The only smart panel architecture that cleanly scales to 400A, 600A, and 800A multi-panel luxury residences
  • +Physical manual override switches on every module provide superior serviceability
  • +Integrates thermostat temperature setpoints with hard circuit relays for smoother HVAC load shedding

Limitations & Watchouts

  • −Requires double the breaker spaces inside the load center (1 space for the breaker + 1 space for the companion relay module)
  • −Sold and commissioned primarily through authorized Savant integrators and certified electrical contractors

Frequently Asked Questions

Why do Savant Power Modules take up extra breaker spaces in the panel?

Because Savant separates UL 489 overcurrent protection (handled by standard Square D QO or Eaton breakers) from UL 916 relay switching and revenue-grade metering (handled by the adjacent Savant companion module). If a relay ever fails 12 years later, you can swap just the snap-in module in 3 minutes.

Can Savant Power System work without a full Savant smart home entertainment system?

Yes. The Savant Power Director operates as a standalone energy and microgrid controller with the Savant Power & Light app—no audio/video host is required.
