The EcoFlow DELTA Pro Ultra is a powerful and affordable home backup system that costs up to 75% less upfront than traditional solar battery setups. It starts with 6kWh of storage and can grow to 90kWh, powering large appliances like central air conditioners and even charging electric vehicles. 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.
This power station is designed to work seamlessly with at least one connected battery, ensuring reliable power delivery and safe system performance. This setup allows the inverter to efficiently manage energy from various sources like solar, grid, or generator, while providing stable output for your home or devices.
Upgrading to firmware version 5.0.0.85 unlocks the ability to switch to a 60 Hz output configuration, providing smoother performance, enhanced device efficiency, and optimal compatibility with regional power standards ensuring you get the most out of your equipment.
