EcoFlow DELTA Pro + 2x DELTA Pro Extra Battery (10.8kWh Bundle)

Is the EcoFlow DELTA Pro Bundle the Ultimate Whole-Home Backup Solution?You've experienced that sinking feeling when the power goes out and you realize your small backup unit can't handle your essential appliances. Your refrigerator, well pump, and HVAC system demand serious power that most portable units simply can't deliver. Without adequate backup capacity, you're looking at spoiled food, no water pressure, and uncomfortable nights while waiting for grid power to return. Critical medical devices go silent. Your home office becomes useless. The EcoFlow DELTA Pro with 2 extra batteries solves this with a massive 10.8kWh capacity system that can power your entire home for days, not hours. 10,800Wh total capacity - Run essential appliances for 3-7 days during extended outages 7200W AC output - Start and run high-draw appliances like air conditioners and well pumps Expandable ecosystem - Add solar panels for unlimited off-grid power generation Smart home integration - Monitor and control remotely via EcoFlow app Ultra-fast charging - Recharge from 0-80% in just 2.8 hours from AC wall outlet LiFePO4 battery chemistry - 6500+ cycle lifespan means decades of reliable service DELTA Pro Bundle Features & PerformanceMassive 10.8kWh CapacityThe base DELTA Pro provides 3.6kWh, and each extra battery adds another 3.6kWh for a total of 10,800Wh. This capacity can run a full-size refrigerator for 7+ days, power essential circuits in your home for 2-3 days, or keep your RV comfortable for a week of off-grid camping. Professional-Grade 7200W OutputWith 3600W continuous output per unit and the ability to chain units together, you'll get 7200W of clean sine wave power. This handles inductive loads like air conditioners, well pumps, and power tools that would trip smaller units.

Why Choose the DELTA Pro Bundle over Traditional Gas GeneratorsUnlike noisy, high-maintenance gas generators, the DELTA Pro system runs silently indoors, requires zero fuel, and needs no regular maintenance. While gas generators demand constant refueling during extended outages, this battery system can run for days and recharge from solar panels for unlimited runtime. EcoFlow has sold over 3 million portable power stations worldwide and backs this system with LiFePO4 batteries rated for 6500+ cycles. That's 15-20 years of regular use, making this bundle a long-term investment rather than a temporary solution. The modular design means you can start with this 3-unit system and expand up to 25kWh capacity as your needs grow, something impossible with fixed-size generators.

The EcoFlow app helps calculate runtime based on your specific loads. Can I add solar panels to this system?Yes, each DELTA Pro unit accepts up to 1600W of solar input, so this bundle can handle 3200W total solar capacity. This enables indefinite off-grid runtime during sunny conditions and significantly extends backup time during outages. Is this bundle worth the investment compared to a gas generator?While the upfront cost is higher, you'll save thousands in fuel costs over the system's 15+ year lifespan. Factor in zero maintenance, silent operation, indoor safety, and the ability to charge from solar, and the total cost of ownership is typically lower than gas generators. How do I connect the extra batteries to the main unit?The extra batteries connect via EcoFlow's proprietary cables (included) and automatically integrate with the main unit's display and app monitoring. Setup takes minutes with no technical expertise required. Warranty & Authorized DealerThis EcoFlow DELTA Pro bundle includes a comprehensive 5-year manufacturer warranty covering all components.
