The EcoFlow DELTA Pro Ultra is a powerful and expandable home backup system that starts with 6kWh of storage and can grow up to 90kWh enough to keep your whole home running during long outages or even go off-grid. Each unit delivers up to 7.2kW of power (10.8kW surge) and can be combined for a total of 21.6kW, ideal for running heavy appliances like air conditioners, water heaters, and more. It switches to backup power in milliseconds, so there’s no interruption during blackouts.
With support for solar charging (up to 16.8kW), gas generator input, and optional EV charging, it offers flexible energy options. The system connects to the EcoFlow Smart Home Panel 2 for control of up to 12 home circuits and real-time app monitoring. Designed to be durable (IP54 rated) and long-lasting (3,500+ cycles), it includes multiple AC, DC, and USB ports—making it a smart, all-in-one energy solution for any home.
