1. Switchover time is based on internal lab testing. Actual performance may vary depending on wiring, load type, and installation environment. 2. Switchover time is based on internal lab testing. Actual performance may vary depending on wiring, load type, and installation environment. 3. By supporting three-level priority management, the backup duration of the core circuit can be extended by approximately 42% under the same SOC conditions, when capacity is concentrated on the core load. Calculation logic: Assumption: SOC = 100, distributed across three circuits with different priorities. Without priority strategy: evenly distributed, approx. 33 per circuit. With priority strategy: Lowest priority = 0 Middle priority = 25 (user-adjustable) Highest priority = 75 Result: 75 − 33 = 42 → the core circuit receives 42% more SOC compared to no-priority allocation. The above calculation is an illustrative example under specific assumptions to explain the allocation logic. Actual backup duration may vary depending on user settings, load characteristics, and operating conditions. 4. Extreme-weather protection is based on EcoFlow internal design and testing. Operating range may vary depending on conditions, installation, and maintenance. 5. Switchover time is based on internal lab testing.

1. The installation time provided is based on EcoFlow’s internal testing under standard conditions. Actual installation time may vary depending on site conditions, system configuration, and installer experience. 2. The installation time provided is based on EcoFlow’s internal testing under standard conditions. Actual installation time may vary depending on site conditions, system configuration, and installer experience. 3. EcoFlow’s 7‑Day Installation Service is calculated in business days, applies only in major metropolitan areas—including Atlanta, Baltimore, Chicago, Dallas, Denver, Detroit, Houston, Las Vegas, Los Angeles, Miami, Minneapolis, New York City, Orlando, Philadelphia, Phoenix, Portland, Salt Lake City, San Diego, San Francisco, San Jose, Seattle, Tampa, and Washington, D.C.—and covers the period starting after (i) the installation service has been purchased and (ii) the later of the product delivery date or the date all required permits/approvals have been obtained, until the completion of the product’s on‑site installation. The 7‑day period does not include delays beyond EcoFlow’s control, including but not limited to: The customer’s failure to confirm the installation date within 2 business days Customer‑requested rescheduling Non‑compliant or unsafe wiring conditions on site Weather conditions Additional permitting processes or inspections Force majeure events 4. “The Fastest Installation” refers to internal comparisons against previous EcoFlow products and reflects improvements in installation process, functionality, and overall performance. Actual installation times may vary depending on site conditions, permitting, and installer availability. 5. Installation Planning timing is estimated and depends on installer availability, homeowner scheduling, access, and local conditions. Findings may affect final scope, price, and timeline. 6. “One-Day Installation” reflects the typical on-site installation time for replacement of an existing electrical panel after permits/approvals, materials, and site readiness are confirmed. Actual timelines vary. The “One-Day Installation” estimate does not apply to scenarios such as: New electrical panel installations (e.g., for new construction or major additions) Major rewiring or circuit modifications within the premises Upgrades from an older panel to a higher-capacity or different type of panel requiring significant electrical system changes Complex site conditions or coordination with utility companies for service disconnection/reconnection These situations typically require additional design, permitting, site preparation, and installation time.

1. Payback Calculation Logic (California Example): Daily solar generation: 10kWp system × 6 sun hours/day) × 0.8 = 48kWh/day. Electricity rates: Average rate: $0.30/kWh. TOU peak/off-peak price differential: $0.30/kWh. Daily savings: Solar savings: 48kWh × 0.30 = $14.4 Battery TOU savings: 12kWh × 0.30 = $3.6 Total daily savings: $14.4+$3.6 = $18 Monthly savings: $18/day × 30 days = $540/month Annual savings: $18/day × 365 days = $6570/year The estimated cost is approximately $18,000, including the equipment purchase and installation for DELTA Pro Ultra X with a Smart Home Panel 3 and two batteries, as well as a 10kW solar panel at market price. Payback Period=$18000/$6570≈3 2. DPUX Tou Saving Logic (California Example): TOU peak/off-peak price differential: $0.30/kWh. Daily savings: Battery TOU savings: 12 kWh × 0.30=$3.6 3. Savings are estimated based on daily consumption of 10kWh, an electricity rate of $0.30 per kWh, and 365 days of use. Actual savings may vary depending on individual usage and electricity rates.
