Description
The EcoFlow DELTA 3 Series Solar Generator (PV400W) is the highest-output solar bundle for the DELTA 3 lineup, pairing the versatile DELTA 3 station with 400W of portable solar panels for maximum daily energy harvest. With 400W feeding into the DELTA 3’s 500W solar input capacity, this bundle delivers near-peak solar recharging and is ideal for users who want to run entirely off the sun.
The DELTA 3 holds 1,024Wh of LFP storage expandable to 5kWh, with 1,800W AC output and 2,200W X-Boost. In good sunlight, 400W of solar can deliver up to 2kWh per day — enough to cover typical camping loads and maintain the battery indefinitely. Fast AC charging at 0 to 80% in ~50 minutes provides a reliable backup when solar isn’t enough. Sub-15ms UPS protects connected electronics.
Cross-series battery compatibility with DELTA 2, DELTA 2 Max, and DELTA Pro 3 batteries. Free 5-year warranty on the DELTA 3.
