Introduction

The EcoFlow DELTA 2 is a compact modular solar generator, designed for home backup, camping, van life, and professional applications. Unlike standard solar generators with fixed capacity, the DELTA 2 features an expandable battery system, starting at 1,024Wh but capable of scaling up to 3,040Wh with an extra battery module.

With 1,800W AC output (2,400W with X-Boost), ultra-fast AC recharging, and 500W max solar input, the DELTA 2 is a future-proof, versatile, and reliable energy solution for both portable and backup power needs. ⚡

📌 Key Differentiator:
Unlike typical fixed-capacity solar generators, the DELTA 2 allows users to expand their battery capacity as needed, making it more flexible for short-term and long-term power needs.
