The DELTA 3 Ultra is EcoFlow's flagship 4kWh system — 4096Wh of EV-grade LFP, 4000W / 8000W output, 48-minute dual charging, 10ms UPS auto-transfer, and expandability to 12kWh+. It can run central AC, whole-home circuits, and sustain a household through a multi-day outage entirely on battery power.
The EcoFlow 400W Portable Solar Panel is EcoFlow's most powerful folding panel. At 400W with up to 23% efficiency and full IP68 waterproof rating, one panel can fully recharge a DELTA 3 Plus in approximately 3 hours of direct sun. The built-in MPPT controller extracts every possible watt as conditions change. Two panels paired with a DELTA 3 Max or DELTA Pro deliver sub-2-hour solar recharges.
• Combine wall charging + 400W solar for maximum recharge speed • Recharge 1×400W panel provides ~2000–2800Wh of free solar energy per day • Set up camp once — solar panels keep you topped off without moving the power station • Run indefinitely off-grid: power station provides immediate backup, solar handles long-term recharge • Single panel covers daily top-up for light to moderate use
