An 18.4kWh DELTA Pro Ultra X system with two genuine EcoFlow 400W portable solar panels. This package gives you 12kW-class 120V/240V backup power, three 6,144Wh LFP batteries and 800W of folding solar that can be moved where the sunlight is best.
Sale price: $10,498 with free shipping in the contiguous United States.
Large Battery Storage Without Giving Up Portable Solar
A lot of whole-home packages assume every customer is ready for a permanent rooftop array. Not everyone is. These two portable 400W panels let you start solar charging immediately and still fold everything away when the storm is over. You can add a larger compatible PV array later because the Ultra X inverter accepts substantially more solar input than the included panels provide.
Bundle Highlights
- 18,432Wh included LFP storage
- Up to 12,000W AC output with 120V/240V support
- Two EcoFlow 400W portable panels for 800W rated solar
- Up to 10,000W total PV input capacity for future expansion
- Expandable Ultra battery architecture
- Fast UPS switchover and app-based monitoring
- Quiet indoor operation without gasoline or exhaust
What Is Included
- 1 × EcoFlow DELTA Pro Ultra X inverter
- 3 × EcoFlow 6,144Wh smart extra batteries
- 2 × EcoFlow 400W portable solar panels
- 2 × kickstand carrying cases
- Solar connection cables and standard system accessories
System Specifications
| Total battery capacity | 18,432Wh |
|---|---|
| Rated AC output | Up to 12,000W; 120V/240V |
| Included solar | 800W total (2 × 400W) |
| Maximum PV input | 10,000W total |
| Panel efficiency | Up to approximately 22.4% |
| Panel weather rating | IP67 |
Important Solar and Output Notes
Actual solar production changes with weather, shading, panel angle and temperature. EcoFlow recommends balancing batteries between the Ultra X powered battery ports when maximum 12kW output is needed. With three batteries, output can depend on the final connection layout.
Popular Uses
- Hurricane and extended-outage preparation
- Refrigeration, lighting, communications and medical equipment
- Central air and well-pump backup after load verification
- Off-grid cabins, workshops and remote properties
Contact AllProGenerators if you want us to check appliance loads, air-conditioner startup requirements or future solar expansion before ordering.
Best Use Cases
- 18.4kWh emergency backup with a portable 800W solar array
- RV, cabin and off-grid power where panels need to fold for transport
- 120V/240V appliance backup during outages
- Expandable solar storage for customers who may add panels or batteries later
EcoFlow DELTA Pro Ultra X Specifications
| AC output | 12,000W, 120/240V split phase |
|---|---|
| Battery capacity | 6,144Wh per Ultra X Smart Extra Battery |
| Solar input | Up to 10,000W total; two 80–500V, 15A, 5,000W PV inputs |
| Expansion | Up to 10 batteries per inverter; up to three inverters in supported systems |
| AC outlets | 2 × NEMA 5-20, L14-30 and 14-50 |
| Transfer time | Under 10ms standalone; under 20ms with Smart Home Panel 3 |
| Inverter size / weight | 26.6 × 18.7 × 9.06 in / approximately 70.1 lb |
| Battery size / weight | 26 × 18 × 8 in / approximately 111.3 lb each |
| Warranty | 5-year standard manufacturer warranty |
Important three-battery output note: EcoFlow specifies that the batteries should be balanced across both powered battery ports to reach the full 12kW output. Three batteries cannot be divided evenly between those ports, so maximum output can be lower than 12kW in some three-battery configurations. Call us before ordering if a specific high-starting-load appliance is critical.
Included Solar Panel Specifications
- Two 400W EcoFlow portable panels; 800W total rated output
- Up to 23% conversion efficiency
- IP68-rated, foldable and self-supporting
- Approximately 42 lb per panel
Frequently Asked Questions
How much battery capacity is included?
The three batteries provide 18,432Wh, or approximately 18.4kWh, of nominal storage.
How fast will two 400W panels recharge the system?
Charge time varies with sunlight, panel temperature, shade, angle, cable losses, battery state and simultaneous loads. An 800W nameplate array will normally produce less than 800W in real conditions.
Can I add more solar panels later?
Yes, provided the complete array remains within the Ultra X PV voltage, current and wattage limits.
Does this include home-panel installation?
No. Home integration equipment and electrician labor are not included unless the product page specifically lists them.
