The EcoFlow Smart Home Panel 2 (SHP 2) is the company's second-generation whole-home backup controller, designed to integrate with the Delta Pro Ultra ecosystem and provide circuit-level control over up to 12 critical loads. After spending time with it as part of a residential backup setup, here's how it actually performs when the lights go out — and when they don't.
TL;DR: The Smart Home Panel 2 is a polished, app-driven transfer panel that delivers genuinely fast failover and granular circuit management. It's a strong fit for homeowners committed to EcoFlow's ecosystem, but installation costs and ecosystem lock-in are real considerations.
Overview and what it does
The Smart Home Panel 2 sits between your main service panel and selected critical loads, automatically switching them to battery power during an outage. Unlike portable inverter-generator setups, the SHP 2 is hardwired and managed entirely through the EcoFlow app, giving you per-circuit control, scheduling, energy monitoring, and integration with Delta Pro Ultra batteries.
Up to 12 dedicated circuits (mix of 120V and 240V)
Under 20 ms automatic failover
Delta Pro Ultra system, up to 3 inverters / 15 batteries
21.6 kW continuous with full stack
EcoFlow app (Wi-Fi/LAN), physical breaker access
Licensed electrician required; sub-panel wiring
Installation and setup
Installation is the first real hurdle. The SHP 2 is not a DIY device for most homeowners — you'll need a licensed electrician, and depending on local code, a permit and inspection. The panel is physically larger than the original Smart Home Panel and requires meaningful wall space adjacent to your main service panel.
Once wired in, app pairing is refreshingly quick. The EcoFlow app walks you through assigning each circuit a name and priority level, and the firmware updates pushed during my testing window were uneventful — no bricked controllers, no failed handshakes. That said, expect a half-day labor commitment on the electrician side, and budget accordingly.
Installation reality check: Plan for $800–$2,000+ in electrician costs on top of the hardware, depending on your panel layout and local rates. This is not optional.
Day-to-day usability
The app is where you'll live with this product, and EcoFlow has matured it considerably. Each of the 12 circuits shows real-time wattage, daily/monthly consumption, and can be toggled on or off remotely. You can set priority tiers so that during an extended outage, lower-priority circuits (a second fridge, a workshop) shed automatically as battery state-of-charge drops.
Scheduling is genuinely useful for time-of-use rate optimization — you can configure circuits to draw from battery during peak hours and recharge off-peak, even without an outage. This is where the SHP 2 starts to pay for itself in markets with steep peak pricing.
Key takeaway: The SHP 2 isn't just a backup device. Its time-of-use arbitrage and circuit-level monitoring make it useful every day, not just during outages.
Performance during outages
I tested failover by pulling the main breaker on several occasions. Transfer was effectively seamless — desktop computers stayed up, the network rack didn't blink, and the only indication anything had happened was a push notification from the app. EcoFlow's sub-20ms claim matches my real-world experience.
With a Delta Pro Ultra and two extra batteries (roughly 18 kWh), a moderately loaded critical-loads panel (fridge, freezer, networking, a few lights, gas furnace blower) ran comfortably for over 24 hours. Adding a third battery comfortably pushes that past two days for similar loads. For more on the battery platform itself, see our EcoFlow DELTA Pro 3 review and the complete DELTA Pro 3 buying guide.
Pros and cons
What works well
- Genuinely fast, reliable automatic transfer
- Granular per-circuit control and monitoring
- Mature, stable app experience
- Time-of-use scheduling saves money daily
- Scales to substantial whole-home capacity
What to watch out for
- Locked to EcoFlow's Delta Pro Ultra ecosystem
- Professional installation is essentially mandatory
- Total system cost climbs quickly with added batteries
- Large physical footprint vs. the original SHP
- App-dependent for most advanced features
Who it's for
The Smart Home Panel 2 makes sense if you're already invested in the Delta Pro Ultra platform, or you're building a backup system from scratch and value app-driven control over the more utilitarian approach of a traditional automatic transfer switch paired with a generator. It's also a strong choice for homeowners in regions with high time-of-use rate spreads, where the daily arbitrage adds meaningful value beyond emergency backup.
It's a poor fit if you want vendor flexibility, if your outages are rare and brief enough that a portable power station with manual extension cords suffices, or if your budget can't absorb both the hardware and a meaningful electrical install bill. In that case, a standalone unit like the Jackery Explorer 2000 Plus or Goal Zero Yeti 1500X may serve you better.
Final verdict
EcoFlow Smart Home Panel 2 — Recommended, with caveats
The SHP 2 is the most refined consumer-grade smart transfer panel I've used. It does what it advertises, the app is solid, and the failover is fast enough that you'll forget the power went out. The caveats are real — ecosystem lock-in and total installed cost — but if you've already chosen EcoFlow's Delta Pro Ultra batteries, the Smart Home Panel 2 is the obvious controller to pair with them.
Frequently asked questions
Can I install the Smart Home Panel 2 myself?
In nearly all jurisdictions, no. This is a hardwired sub-panel installation that requires a licensed electrician and typically a permit. Attempting a DIY install can void warranties and create serious safety and code-compliance issues.
Does the SHP 2 work with older EcoFlow batteries like the original Delta Pro?
No. The Smart Home Panel 2 is designed specifically for the Delta Pro Ultra system. The original Delta Pro pairs with the first-generation Smart Home Panel instead. If you're considering a smaller EcoFlow setup instead, our EcoFlow Delta 2 review covers a more portable alternative.
How many circuits can it manage?
Up to 12 circuits, with a mix of 120V single-pole and 240V double-pole supported. This is enough for most critical-loads scenarios but won't cover an entire large home's circuit list.
Does it require an internet connection to work?
No. Core failover and circuit management work locally. Internet is required for remote app access, firmware updates, and some scheduling features, but a power outage with downed internet won't stop the panel from doing its primary job.
Can it charge from solar?
The SHP 2 itself doesn't manage solar — that's handled by the Delta Pro Ultra inverters it pairs with. Those inverters accept substantial solar input, so a full system can absolutely run on solar charging.
