Model: EcoFlow DELTA Max 1600 + 1*400W Solar Panel

The EcoFlow DELTA Max Power Station, when paired with the highly efficient 400W Portable Solar Panel, provides a comprehensive and robust solution for ensuring your home remains powered during emergencies. This setup is designed for high efficiency and versatility, perfect for sustaining large appliances during blackouts or for use in remote, off-grid environments.

Key Features:

  • Expandable Home Backup Power: Starting with a 2kWh capacity, the DELTA Max can be expanded up to 6kWh with the addition of DELTA Max smart extra batteries. This feature ensures that crucial home devices such as fridges and lighting can keep running for hours during power outages.

  • Rapid and Versatile Dual Charging: The DELTA Max powers up quickly and safely, charging from 0-80% in just 65 minutes. For enhanced speed, it can be charged using AC for up to 3400W, or combined with the EcoFlow Smart Generator and solar panels for up to 2600W, ensuring you have flexibility in how and where you recharge.

  • High-Capacity Device Management: Thanks to EcoFlow’s X-Boost technology, the DELTA Max can efficiently power heavy-duty devices up to 3400W, making it ideal for running high-demand appliances like fridges and dryers during a blackout.

  • Highly Efficient Solar Panels: The 400W Portable Solar Panel is one of the most potent foldable panels available, with a conversion efficiency of 22.4%. It is designed to be self-supporting with an adjustable stand that ranges from 40-90°, allowing for optimal sun exposure and maximum power generation even in less than ideal weather conditions.

  • Durable and Lightweight Design: Weighing only 12.5 kg, the solar panel combines the flexibility of EVA and the strength of durable fiberglass. It is covered with an ETFE film to protect against environmental elements and is IP67 rated for waterproofing, making it perfect for both outdoor adventures and home rooftop installation.

  • Smart Solar Energy Utilization: The panel uses a universal MC4 connector for broad compatibility with all EcoFlow DELTA Series power stations and many third-party generators. It features a smart MPPT algorithm that adjusts efficiency in real-time, ensuring you get the most out of the solar energy collected throughout the day.

  • Emergency Backup and Remote Management: In prolonged power outages, the DELTA Max, integrated with the EcoFlow Smart Generator, provides a reliable backup by automatically starting when power levels are low and stopping once fully charged. Manage and monitor your power setup remotely via the EcoFlow app, giving you control to customize settings and optimize usage based on your needs.

The combination of the EcoFlow DELTA Max and the 400W Portable Solar Panel offers a powerful, sustainable solution for maintaining energy independence and resilience in emergencies or for day-to-day use in off-grid settings. This pairing not only ensures that you stay powered but also supports an eco-friendly lifestyle by harnessing solar power.


  • Expandable Home Backup Power: DELTA Max starts with a 2kWh capacity and can expand up to 6kWh with smart extra batteries, ensuring continuous operation of essential home devices like fridges and lights during blackouts.
  • Convenient and Fast Dual Charging: Charges from 0-80% in just 65 minutes. For faster charging, options include combining AC with the smart generator for up to 3400W, or AC with solar and the smart generator with solar for up to 2600W.
  • Power 99% of Home Devices: Equipped with X-Boost technology, DELTA Max powers devices up to 3400W, allowing you to run heavy-duty appliances like fridges and dryers during outages.
  • Solar Power Efficiency: Connect up to two 400W EcoFlow solar panels for up to 800W of maximum solar charging. Supports a voltage range of 11-100V and includes a solar connector. Features smart MPPT that optimizes solar generation.
