EcoFlow DELTA Pro Ultra Inverter + Batteries
Are you looking for an affordable home battery backup system that can run almost everything in your house when the grid is down? The EcoFlow DELTA Pro Ultra Home Battery Backup System is an affordable and powerful whole-home backup system which uses advanced lithium-ion batteries instead of the noisy backup generators of the past.
This comprehensive solution gives you a proper battery backup for home use, ensuring you have a reliable power source for prolonged outages and daily usage. The EcoFlow DELTA Pro Ultra Inverter is the heart of this home backup battery system - each inverter has 7200W continuous AC output, peaking at 10.8 kW, allowing you to run almost any home appliance, even a 3-ton air conditioner. Each Delta Pro Ultra Inverter can be connected with up to five 6 kWh lithium iron phosphate (LFP) batteries to form an inverter and battery stack. Each inverter/battery stack is plugged into an EcoFlow Smart Home Panel 2 (sold separately), wired into your main electrical panel. The Smart Home Panel 2 can accommodate up to 3 inverter/battery stacks, for a possible total of an impressive 90 kWh of backup battery capacity.
Integration with the EcoFlow Smart Home Panel 2, along with EcoFlow Delta Pro Ultra Expansion Batteries, delivers a seamless power backup experience featuring automatic switchover, energy consumption monitoring, and potential cost savings on electricity bills through advanced EcoFlow app settings.
As well, in combination with the EcoFlow app, the sophisticated EcoFlow PowerInsight Home Energy Manager (sold separately) touchscreen can serve as an all-in-one energy dashboard, displaying power generation, warning of impending severe weather events, and showing the status of all connected appliances.
The plug-and-play stackable design facilitates quick expansion of EcoFlow Delta Pro Ultra storage and output. The EcoFlow Delta Pro Ultra can accept charging input from solar panels, a generator like the EcoFlow Dual-Fuel Generator, or grid power, flexibly adapting to your power requirements as you need.
Month-Long Power Security
Take home power dependability to another level with up to 90kWh of stored energy. For a standard household, that's over 30 days of essential backup power to keep appliances like lights and refrigerators running strong (time may vary). Stackable and space-saving, the EcoFlow Delta Pro Ultra is a battery power system that packs comfortably into a garage or utility closet.

FAQ
FAQ
How does the Power Hub communicate the voltage to the Smart Distribution panel?
There are two included RJ45 network cables included in a Independence Power Kit. One that connects the Power Hub directly to the Smart AC/DC Distribution Panel; a second one to connect the Power Hub to the Power Kit Console.
What is the operating temperature range of the Power Kit Console?
The information as stated in the user manual is below: -20C to 50C (-4F to 122F). This is the operating temperature range for all
Power Kit components.
What is considered a standard alternator input scenario and what is else is allowed involving alternator charging with EcoFlow Power Kits?
All 3x PV/ALT input ports can be used as alternator charging ports. The first ATL-IN input port can allow 70A max and 1600W input max, meaning that if you draw from 12V alternator you can only get 13.6V x 70A = 952W which is almost 1000 (it will fluctuate between 950W and 1000W). If a 48V alternator is connected to port 1, then an estimated 54V x 29.6A = 1600W is expected. The 2nd and 3rd ALT-IN input ports are both 30A max and 1600W max. If you connect a 12V alternator to these ports, an estimated 13.6V x 30A = 408W each is expected. If you connect a 48V alternator to ALT-IN 2 or 3 ports, an estimated 54V x 29.6A = 1600W each is expected. If you connect a 12V alternator on all 3 ALT-IN input ports, an estimated 952W + 408W + 408W = 1768W (if your 12V alternator can deliver 70A + 30A + 30A = 130A) is expected. If you use 48V alterantor on all 3 ports, an estimated 1600W + 1600W + 1600W = 4800W input is expected.
What type of shore power inlet is recommended for an EcoFlow Power Kit?
The Power Kit allows up to 30A input, so we recommend 30amps max. 30A to 15A converters are available if your enegy consumption needs are not high. Furrion is a tested and trusted brand that has worked perfectly with an EcoFlow Power Kit.
