Introduction

The EcoFlow DELTA Max is a modular solar generator, designed for home backup, off-grid power, RVs, and professional use. Unlike standard solar generators with fixed capacity, the DELTA Max features expandable battery options, starting at 2,016Wh but scaling up to 6,048Wh with two extra battery modules.

With a 2,400W AC output (5,000W surge), ultra-fast AC recharging, and 800W max solar input, the DELTA Max is a reliable, flexible, and high-powered energy solution. ⚡

📌 Key Differentiator:
Unlike traditional fixed-capacity solar generators, the DELTA Max allows users to expand their battery capacity as needed, making it ideal for short-term and long-term power applications.
