Feature Bullets

• 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 forms a whole home backup system to ensure that your home can be powered 24/7 without any influence from power outage
• 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 whisperquiet 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 30 kWh to 90 kWh
