Our Top Picks

SPAN Smart Electrical Panel

Tiered Quote
Pros
  • Completely replaces the massive, ugly legacy box in your garage
  • Incredible, award-winning app visualizing exactly what circuit is pulling power
  • Dynamic load shedding algorithms stretch a small battery system over multiple days of a power outage
Cons
  • Astronomically expensive when factoring in the required certified electrician labor to rip out your old box entirely
  • If the SPAN internal computer ever dies, physical breaker resets can become highly frustrating
SPAN.io entirely reinvented the paradigm. Built by former Tesla energy executives, the SPAN panel does not sit next to your old breaker box; it completely obliterates it. It is a full, ground-up replacement. The true magic is its "Load Shedding" architecture during a blackout. If a catastrophic storm knocks out the grid, SPAN instantly detects the failure. Relying completely on your stored battery power, its algorithm will automatically shut down the circuits leading to your heated floors or EV charger (designated as non-essential), while strictly ensuring that the circuit leading to your refrigerator and CPAP machine never loses a single millisecond of power. It dramatically increases the effective lifespan of your connected solar battery array during emergencies.

Lumin Smart Panel

From $2,500
Pros
  • Does not require ripping out your existing electrical panel
  • Acts as an incredibly intelligent "sub-panel" for specific, high-draw circuits
  • Significantly cheaper installation costs than a full SPAN replacement
Cons
  • You must pre-select which specific circuits you care about making "smart" during installation
  • Lacks the holistic "whole-home" visual beauty within its mobile interface
The primary financial barrier to smart panels is labor; ripping out 40 thick copper wires from a 1980s breaker box and re-terminating them inside a SPAN panel is a $5000+ electrical nightmare. Lumin solves this via the "retrofit" paradigm. The Lumin box sits immediately adjacent to your existing, dumb electrical panel. You take only the 6 to 8 most critical circuits you care about (your well pump, freezer, EV charger, and HVAC compressor) and reroute them through the Lumin box. The result? You get 90% of the massive load-shedding and battery prioritization benefits without touching the remaining 30 analog circuits in your house that power random living room lightbulbs. It is an incredibly strategic, highly cost-effective upgrade.

EcoFlow Smart Home Panel 2

$1,899
Pros
  • Flawless, native, proprietary integration with the massive Delta Pro Ultra battery towers
  • Beautifully unifies EV charging, solar inputs, grid power, and battery storage into one single app ecosystem
  • Ultra-sleek monolithic aesthetic on the garage wall
Cons
  • Incredibly walled-off; completely useless if you eventually decide to switch to Tesla or Franklin batteries
  • Only supports up to 12 specific circuits rather than essentially unlimited circuits like SPAN
If you already committed to investing $15,000 into a towering stack of EcoFlow Delta Pro Ultra battery units instead of buying massive Tesla Powerwalls, then purchasing the EcoFlow Smart Home Panel 2 is absolutely mandatory. While Lumin and SPAN aim to be "platform agnostic" smart hubs that talk to an array of different solar inverters, EcoFlow built a closed, highly-polished ecosystem mimicking the "Apple" approach. It perfectly routes the massive 7.2kW input from your EcoFlow towers into your critical home circuits effortlessly, completely bypassing the massive integration nightmares characteristic of trying to jury-rig third-party components together.

How This Was Tested

Evaluating Smart Panels requires moving completely beyond aesthetic app design. The sole reason to purchase an intelligent electrical panel is Load Shedding during grid instability. Testing aggressively evaluated the speed at which these internal algorithms identified a massive "Grid Down" scenario, specifically how reliably they instantly severed the connection to massive 240v air conditioning condensers to prevent rapidly draining the expensive, limited home battery supply.

Frequently Asked Questions

YES. In traditional dumb systems without batteries, your solar panels automatically shut down during a neighborhood blackout strictly to prevent deadly voltage from back-feeding into the grid while linemen are working on it. Smart panels orchestrate a massive physical "islanding" disconnect between your house and the grid, safely "tricking" your solar inverters into turning back on and powering your house while the sun is up.

Absolutely not. You are interacting directly with the lethal 200-amp main service lines feeding your entire house from the street. Attempting to DIY a smart panel replacement is a massive risk of immediate electrocution and will certainly result in a catastrophic, uninsurable domestic house fire.
