EcoFlow Delta Pro Ultra Review: Unleashing Home Backup Power

Delta Pro Ultra Review – EcoFlow DELTA Pro Ultra is a residential power backup system designed for both extended outages and daily use. With its unrivaled capacity, input power, and output power, a single unit can run your entire home.

1. Delta Pro Ultra Key Features

• Continuous Power
  With EcoFlow DELTA Pro Ultra’s UPS technology, you’ll get impeccable, uninterrupted power flow. EcoFlow DELTA Pro Ultra safeguards your vulnerable electronic equipment round-the-clock. For extended outages, you don’t want to hear your backup in the background, so for low draws under 2000W, it’s completely silent. With a whisper-quiet 0 dB, your nights remain undisturbed as it powers your devices.
• Expandable Capacity
  The rated capacity of one battery is 6kWh. To expand capacity for powering your appliances (see Overview or Power Your Appliances) or backing up your whole home (see Backup System), one can connect up to 5 batteries to an inverter or up to 15 batteries to 3 sets of inverters, which makes the total capacity add up to about 30kWh to 90kWh.
• Home Backup
  The DELTA Pro Ultra can either be used as a stand-alone unit using various recharging options (low/high voltage solar systems, generators, EV chargers, etc.) or form a whole home backup system to ensure that your home can be powered 24/7 without any influence from power outages.

2. Open the protective covers and connect the battery connection cable.
3. An inverter supports up to 5 batteries. During installation, please note that battery connection cables should be installed in the right sequence as in the illustration. If you connect more than 3 batteries, lock the brakes of the mount casters after installation.

5.2 Mounting Two Sets Of Units

If you have 2 sets of products, you can put one set on top of the other set. Note that the top set should be installed with supporting legs instead of casters.

CAUTION

• For this installation option, one can connect up to two batteries to an inverter.
• The EcoFlow Fixing Metal Tabs need to be fixed to the battery under the top inverter.

5.3 Mounting On A Shelf

If you plan to put the inverter and the battery in different places (for example, on a shelf, on the ground, etc.), you can connect them with a 0.75 meter-long battery connection cable.

5.4 Mounting On The Trolley

To easily move the product, you can also mount the set on the trolley, but please note that you can only mount one inverter and one battery on the trolley.
