Step 1: Pre-Installation Planning & Circuit Selection

The most important phase of any Smart Home Panel 3 installation happens before you pick up a single tool. Proper planning ensures your system delivers power to the circuits that matter most while staying within the capacity of your EcoFlow power station.

Assess Your Power Needs

Begin by identifying which circuits in your home are essential during an outage. Common choices include:

• Refrigerator and freezer circuits
• Kitchen outlets (for cooking and small appliances)
• Lighting circuits (hallways, bedrooms, living areas)
• HVAC blower or furnace circuit
• Well pump (if applicable)
• Garage door opener
• Home office outlets and internet equipment
• Sump pump
• Medical equipment circuits

The EcoFlow Smart Home Panel 3 supports up to 10 selectable circuits, giving you flexibility to prioritize the loads that keep your household running comfortably. Keep in mind that your total selected load must not exceed the output capacity of your connected EcoFlow power station.

Map Your Existing Electrical Panel

Open your main electrical panel and create a detailed circuit map. Note the amperage rating of each breaker, the wire gauge connected to it, and the area or appliance it serves. This information is invaluable when you begin transferring circuits to the Smart Home Panel 3.

Use your label maker to clearly tag each circuit in both your main panel and your new Smart Home Panel 3. Color-coded electrical tape on wires adds an extra layer of clarity and reduces the chance of errors during the wiring phase.

Choose the Mounting Location

The Smart Home Panel 3 should be mounted:

• Within 3–6 feet of your main electrical panel (to minimize wire runs)
• On a sturdy wall with studs that can support the unit's weight
• In a dry, indoor location protected from direct moisture
• With adequate clearance on all sides for ventilation and future maintenance
• Within reach of your EcoFlow power station's connection cable

Mark the mounting location with a pencil and use your level to ensure the bracket will sit perfectly straight. Pre-drill holes into wall studs for a secure mount.

Check Local Electrical Codes

Before proceeding, review your local electrical codes and permit requirements. Many jurisdictions require a permit for any modification to your home's electrical system, and inspections may be necessary after installation. Working with a licensed electrician ensures compliance and protects your homeowner's insurance coverage.

Step 2: Mounting the Smart Home Panel 3 & Preparing Wiring

With your plan finalized, it is time to physically install the Smart Home Panel 3 and prepare the wiring pathways between it and your main electrical panel.

Mount the Panel

1. Attach the mounting bracket to the wall using the pre-drilled holes. Secure it with lag bolts driven into wall studs for maximum stability.
2. Hang the Smart Home Panel 3 onto the bracket and secure it with the provided mounting screws.
3. Verify the unit is level and firmly attached. Give it a gentle shake to confirm there is no movement.
4. Open the front cover of the Smart Home Panel 3 to access the internal terminal blocks and breaker slots.

Run Conduit Between Panels

You need a protected pathway for the wires traveling between your main electrical panel and the Smart Home Panel 3. Depending on your setup:

• Surface-mounted conduit (EMT): Use rigid or EMT conduit with appropriate fittings. This is the most common approach when both panels are on the same wall.
• Flexible conduit: Ideal for short runs or when panels are at slightly different angles.
• In-wall wiring: If the panels are on opposite sides of a wall, you may route wires through the wall cavity using appropriate fire-rated methods.

Cut and install the conduit, securing it with straps every 3 feet as required by code. Leave adequate slack at both ends for wire pulling.

Pull the Wires

Using your fish tape, pull the required wires through the conduit:

• Two hot wires (for 240V split-phase service) — typically black and red, 6 AWG or 4 AWG
• One neutral wire — white, same gauge as the hot wires
• One ground wire — green or bare copper, same gauge or one size smaller per local code

Leave at least 12 inches of wire extending into each panel for comfortable termination. Label each wire at both ends with its function and destination.

Prepare the Communication Cable

The Smart Home Panel 3 communicates with your EcoFlow power station via a dedicated communication cable. Route this cable from the Smart Home Panel 3 to the location where your EcoFlow DELTA Pro or DELTA Pro Ultra will sit. Keep this low-voltage cable separated from high-voltage wiring by at least 6 inches to prevent electromagnetic interference.

Step 3: Wiring the Smart Home Panel 3 to Your Main Electrical Panel

This is the most critical and complex phase of the installation. If you are not a licensed electrician, this step should be performed by a qualified professional. Working inside your main electrical panel exposes you to lethal voltages, even when the main breaker is turned off, because the utility service entrance conductors remain energized.

Shut Off Main Power

1. Turn off the main breaker in your electrical panel to de-energize all branch circuit breakers.
2. Verify power is off using a non-contact voltage tester on multiple circuits and a multimeter on the bus bars.
3. Place a lockout/tagout device on the main breaker if available, or place a sign warning others not to restore power while you work.
4. Notify all household members that electrical work is in progress.

Connect the Feed from the Main Panel

The Smart Home Panel 3 receives power from your main panel through a dedicated double-pole breaker. Here is how to make the connection:

1. Install a double-pole breaker in your main panel. The amperage rating should match the Smart Home Panel 3's rated input (typically 30A or 50A, depending on your configuration and power station capacity).
2. Connect the two hot wires from the conduit to the double-pole breaker terminals. Tighten to the manufacturer's specified torque.
3. Connect the neutral wire to the neutral bus bar in your main panel.
4. Connect the ground wire to the ground bus bar (or combined neutral/ground bar if your panel uses one).

Wire the Smart Home Panel 3 Input Terminals

On the Smart Home Panel 3 side:

1. Connect the two hot wires to the main input terminals labeled L1 and L2.
2. Connect the neutral wire to the neutral bus bar inside the Smart Home Panel 3.
3. Connect the ground wire to the ground bus bar or ground terminal.
4. Double-check all connections for tightness and proper seating. Tug gently on each wire to confirm it is secure.

Transfer Selected Circuits

Now you move the circuits you identified during planning from your main panel to the Smart Home Panel 3:

1. Remove each selected circuit's hot wire from its breaker in the main panel.
2. Extend the hot wire using a wire nut or WAGO connector and an appropriate length of matching-gauge wire, routing it through the conduit to the Smart Home Panel 3.
3. Connect the extended hot wire to the corresponding breaker in the Smart Home Panel 3.
4. Move the circuit's neutral wire from the main panel's neutral bar to the Smart Home Panel 3's neutral bar. If the circuit shares a neutral with another circuit (multi-wire branch circuit), you must handle both circuits together or reconfigure the wiring to avoid dangerous neutral overload conditions.
5. Ensure the ground wire remains connected to the ground system (grounds are typically bonded at the main panel and do not need to be moved).

Repeat this process for each of the circuits you want to back up — up to the panel's maximum of 10 circuits.

Handle Multi-Wire Branch Circuits (MWBCs)

Many modern homes use multi-wire branch circuits, where two hot wires share a single neutral. If you move only one leg of an MWBC to the Smart Home Panel 3, the shared neutral can become overloaded. Always identify MWBCs during planning and either:

• Move both legs of the MWBC to the Smart Home Panel 3
• Install a handle-tied double-pole breaker in the Smart Home Panel 3
• Reconfigure the circuit to eliminate the shared neutral (consult an electrician)

Step 4: Connecting the EcoFlow Power Station & System Configuration

With all high-voltage wiring complete, it is time to connect your EcoFlow power station and configure the system for automatic backup operation.

Connect the Communication Cable

1. Plug the communication cable into the designated port on the Smart Home Panel 3.
2. Connect the other end to your EcoFlow DELTA Pro or DELTA Pro Ultra's smart connection port.
3. Ensure the connection is snug and the cable is routed safely away from any high-voltage wires and moving parts.

Connect the Power Input Cable

Depending on your specific EcoFlow model and configuration, you may need to connect a dedicated power input cable between the Smart Home Panel 3's output terminals and your power station's input. Follow the wiring diagram included in your Smart Home Panel 3's documentation precisely. Different configurations exist for:

• Single DELTA Pro setup (up to 3,600W output)
• Dual DELTA Pro setup with the Double Voltage Hub (up to 7,200W output)
• DELTA Pro Ultra configuration (scalable up to 7,200W per inverter)

Restore Main Power and Test the Feed

1. Close the Smart Home Panel 3's front cover securely.
2. Turn the main breaker back on in your electrical panel.
3. Turn on the double-pole breaker that feeds the Smart Home Panel 3.
4. Use your multimeter to verify that the Smart Home Panel 3 is receiving proper voltage (approximately 120V on each leg to neutral, 240V between legs).
5. Check that all transferred circuits are receiving power from the grid through the Smart Home Panel 3.

Configure the EcoFlow App

1. Open the EcoFlow app on your smartphone or tablet.
2. Navigate to the Smart Home Panel 3 in your device list.
3. Follow the on-screen setup wizard to pair the panel with your account and configure your Wi-Fi connection.
4. Name each circuit in the app to match the physical loads they serve (e.g., "Kitchen Outlets," "Bedroom Lights," "Refrigerator").
5. Set your backup priorities — the app allows you to define which circuits should be powered first when the battery capacity is limited.
6. Configure automatic switchover settings — the Smart Home Panel 3 can detect grid outages and automatically switch your selected circuits to battery power in milliseconds.
7. Set charging schedules if you want your EcoFlow power station to charge during off-peak hours and discharge during peak hours for energy cost savings.

Test the Backup Switchover

Simulate a power outage to verify everything works correctly:

1. Turn off the main breaker in your electrical panel to simulate a grid outage.
2. Observe the Smart Home Panel 3 — it should detect the outage and signal your EcoFlow power station to begin supplying power within seconds.
3. Verify that all selected circuits are receiving power from the battery.
4. Check the EcoFlow app to confirm it reports the outage and shows real-time power flow data.
5. Turn the main breaker back on and confirm the system seamlessly transitions back to grid power.

If your system passes this test, congratulations — your EcoFlow Smart Home Panel 3 installation is complete and operational.

Troubleshooting Common Installation Issues

Even with careful planning, you may encounter issues during or after installation. Here are solutions to the most common problems.

The Smart Home Panel 3 Does Not Power On

• Verify the double-pole breaker in the main panel is fully in the ON position.
• Check all wire connections at the input terminals (L1, L2, neutral, and ground).
• Use a multimeter to confirm 240V is reaching the Smart Home Panel 3's input terminals.
• Inspect the internal fuse (if applicable) and replace it if blown.

Circuits Are Not Receiving Power in Grid Mode

• Confirm each circuit breaker inside the Smart Home Panel 3 is in the ON position.
• Check that the hot wire from each transferred circuit is properly connected to its breaker terminal.
• Verify neutral wires are securely connected to the neutral bus bar.
• Look for tripped GFCI or AFCI breakers that may have tripped during installation.

Automatic Switchover Does Not Trigger During Outage

• Ensure the communication cable is securely connected at both ends.
• Verify your EcoFlow power station is turned on and has sufficient battery charge.
• Check the EcoFlow app for firmware updates — update both the Smart Home Panel 3 and the power station to the latest firmware.
• Confirm the power station's output capacity is not exceeded by your selected circuits.
• Reset the Smart Home Panel 3 by powering it off and on using the main switch.

EcoFlow App Cannot Find the Smart Home Panel 3

• Move closer to the panel during initial setup to ensure strong signal reception.
• Restart the EcoFlow app and your phone, then attempt pairing again.
• Perform a factory reset on the Smart Home Panel 3's communication module (refer to the user manual for reset instructions).

Breaker Trips Immediately When Turned On

• A breaker that trips instantly typically indicates a short circuit or a ground fault.
• Disconnect the load from the circuit and test the breaker alone — if it holds, the problem is in the wiring or the connected appliance.
• Inspect all wire connections for bare copper touching the panel enclosure or other wires.
• Check for damaged wire insulation that may have occurred during wire pulling.
• If the issue persists, consult a licensed electrician to perform an insulation resistance test.

Unusual Noise or Heat from the Panel

• A slight hum from breakers is normal, but loud buzzing indicates a loose connection or failing breaker.
• Use a thermal imaging camera to check for hot spots at terminal connections — any connection significantly warmer than surrounding components needs to be tightened or replaced.
• Ensure the total load on any individual breaker does not exceed 80% of its rated capacity for continuous loads.

Frequently Asked Questions

Do I need a licensed electrician to install the EcoFlow Smart Home Panel 3?

While experienced DIYers with electrical knowledge can physically mount the panel and run conduit, we strongly recommend hiring a licensed electrician for all connections inside your main electrical panel. Working near the service entrance conductors is extremely dangerous, and improper wiring can cause fires, equipment damage, or void your homeowner's insurance. Many local jurisdictions also require a permit and inspection for this type of work, which typically must be signed off by a licensed professional.

How many circuits can the EcoFlow Smart Home Panel 3 support simultaneously?

The EcoFlow Smart Home Panel 3 supports up to 10 individual circuits. You can select any combination of 120V and 240V circuits from your main panel, provided the total load does not exceed the output capacity of your connected EcoFlow power station. For a single DELTA Pro, the maximum continuous output is 3,600W (surge up to 4,500W). With a dual DELTA Pro setup using the Double Voltage Hub, you can achieve up to 7,200W of continuous output, which is sufficient for most essential household circuits.

Will the Smart Home Panel 3 work with solar panels already installed on my home?

Yes, the EcoFlow Smart Home Panel 3 is compatible with existing solar panel systems. When the grid is operational, your solar system continues to function normally through your main panel. During an outage, the Smart Home Panel 3 isolates your selected circuits and powers them from your EcoFlow battery. If you have an EcoFlow solar panel setup connected directly to your DELTA Pro or DELTA Pro Ultra, the system can use solar energy to recharge the battery during an outage, effectively extending your backup runtime indefinitely on sunny days. Always ensure your installation complies with local interconnection requirements and that anti-islanding protections are properly configured.

How fast is the switchover time when the grid goes down?

The EcoFlow Smart Home Panel 3 features an automatic transfer switch with a switchover time of approximately 20 milliseconds. This is fast enough to keep most electronics running without interruption — computers, routers, televisions, and LED lights typically will not even flicker during the transition. However, some sensitive equipment with very tight power tolerances may briefly reset. If you have critical medical equipment or servers that require zero-interruption power, consider adding a dedicated UPS (uninterruptible power supply) for those specific devices as an extra layer of protection.

Can I monitor and control the Smart Home Panel 3 remotely?

Absolutely. The EcoFlow Smart Home Panel 3 connects to your home Wi-Fi network and is fully controllable through the EcoFlow app, available for iOS and Android. From the app, you can monitor real-time power consumption for each individual circuit, view battery status and estimated runtime, manually switch circuits on or off, set backup priorities and schedules, and receive push notifications during power events. The app also provides historical energy usage data, helping you optimize your circuit selection and energy consumption patterns over time. As long as your phone has an internet connection and your home Wi-Fi is operational (or you have a cellular-connected router on a backed-up circuit), you can manage your system from anywhere in the world.
