Bundled with two 200W portable solar panels, this complete kit can recharge from the sun in as little as 3-5 hours, making it the most capable solar generator ever designed for residential use.

About This Item

• Massive 3,840Wh LiFePO4 Capacity: Store enough energy to run a refrigerator for 38+ hours, charge 75+ smartphones, power a 1,000W air conditioner for nearly 4 hours, or keep essential home appliances running through extended grid outages. LiFePO4 chemistry guarantees safety and 3,000+ charge cycles (10+ year lifespan).
• 4,000W Pure Sine Wave Output: Powers virtually any household appliance with clean, stable electricity. The X-Boost technology allows it to run appliances up to 4,800W peak — including washing machines, microwaves, power tools, and air conditioners that typically require a fixed installation.
• 400W Solar Input – Full Charge in 3-5 Hours: The included dual 200W portable solar panels (400W combined) can fully recharge the DELTA Pro 3 in 3-5 hours of direct sunlight. Supports up to 1,600W of solar input for even faster off-grid charging.
• Whole-Home Panel Integration: Optionally connects directly to your home’s electrical panel via the EcoFlow Smart Home Panel, allowing it to automatically power selected home circuits during grid outages — without any manual switching required.
• Dual-Direction EPS Mode: When grid power fails, the DELTA Pro 3 switches to backup power in under 30ms — faster than most electronics can detect. This Uninterruptible Power Supply (UPS) mode ensures computers, servers, and sensitive electronics are never disrupted.
• Expandable to 25,600Wh: Add up to five extra DELTA Pro 3 batteries to expand capacity to an enormous 25,600Wh — enough to power a family home through multiple days of grid outages. All expansion batteries connect via a single cable.
• EcoFlow App Remote Monitoring: Monitor battery status, solar input, power consumption, and control all charging modes remotely via the EcoFlow app on iOS and Android. Includes smart scheduling and usage analytics for energy optimization.
