Ecoflow's Most Powerful System:
• | The perfect option for Refrigeration, Lighting, TVs, Computers, Smart Devices, Fans, Washers, and so much more! |
• | The Delta Pro Ultra is scalable from one battery of 6kWh, all the way to 15, it multiplies the energy to a gigantic 90kWh. |
• | Requires no gas and emits no pollution. |
• | Informative LED Screen displays watt input/output and remaining run time. |
• | Includes a 400W Foldable Solar Panel for green Off-grid recharging! |
• | The Delta Pro Ultra is scalable from one battery of 6kWh, all the way to 15, it multiplies the energy to a gigantic 90kWh. For a standard household during a blackout, that's over 30 days of essential power to keep appliances like lights and refrigerators running strong (time may vary depending on use). |
• | Start small and portable and work your way up to an entire home system! |
