EF ECOFLOW DELTA 2 Portable Solar Generator 1024Wh Kit with 2×100W Panels — 1800W Continuous, LFP Battery

The EF ECOFLOW DELTA 2 with two 100W solar panels is a 1024Wh portable solar generator delivering 1800W continuous (2700W surge) power and fast solar recharging for off-grid use.

Compact but capable, this kit combines a lightweight 1kWh lithium iron phosphate (LFP) power station with two efficient 100W solar panels to create a quiet, fuel-free alternative to small gas generators. Designed for camping, tailgates, RVs, or emergency backup, the DELTA 2 supports multiple devices at once while offering long battery life and expansion options. Panels ship separately from the main unit.

How quickly will the DELTA 2 recharge using the included solar panels?

Solar charging speed depends on panel count and sunlight conditions. With the two included 100W panels under ideal sun, expect about 5.1 hours to fully recharge; adding a third panel reduces full recharge time to roughly 2.6 hours. EF ECOFLOW’s panels are optimized with a 23% conversion rate to make the most of available sunlight.

• Two 100W panels: ~5.1 hours to full charge in strong sun
• Optional third 100W panel: ~2.6 hours to full charge
• 23% solar conversion rate for efficient energy capture

What appliances and devices can this 1800W unit power?

The DELTA 2 supplies 1800W continuous output with a 2700W surge, enough for many household and outdoor appliances. It can run most tools, kitchen appliances, and personal electronics, supporting up to 15 devices simultaneously through a mix of AC, DC, and USB ports. Remember peak surge ratings for motor-driven devices like pumps or blenders.

• 1800W continuous, 2700W surge for short power spikes
• 15 total outlets for AC, DC, and USB devices
• Suitable for laptops, small fridges, power tools, and lights

How durable is the battery and how long will it last?

DELTA 2 uses LFP (lithium iron phosphate) cells, chosen for long lifespan and stable chemistry. The battery is rated for 3,000+ cycles, meaning years of daily use before significant capacity loss. A built-in battery management system (BMS) handles cell balancing, temperature control, and safety monitoring for reliable performance.

• LFP chemistry for extended cycle life (3,000+ cycles)
• Integrated BMS for safety and automatic regulation
• Resilient design for repeated charge/discharge use

Can I expand capacity and how does setup work?

The base DELTA 2 provides about 1kWh of usable energy, and it’s designed to scale: you can expand total capacity up to roughly 3kWh by adding compatible battery modules. Setup is straightforward—connect extra batteries or solar panels to increase runtime, and note that the two 100W panels included will ship separately from the main unit.

• Expandable from 1kWh up to ~3kWh with add-on batteries
• Plug-and-play connections for extra panels and batteries
• Panels and generator may arrive in separate shipments

Who this is for: The EF ECOFLOW DELTA 2 kit suits weekend campers, vanlifers, and homeowners wanting quiet, low-maintenance backup power without gasoline. It’s ideal for people who need multi-outlet flexibility, fast solar recharge, and a long-lasting battery chemistry—anyone seeking portable, scalable power for outdoor adventures or emergency readiness.
