Product Description

The EcoFlow DELTA 3 Plus is a versatile portable power station designed for home backup, professional use, travel and off-grid applications.

Its 1024Wh LiFePO4 battery provides rechargeable stored energy without the fumes, fuel storage or routine engine maintenance associated with conventional generators.

The power station delivers 1800W continuous pure-sine-wave AC output with a surge capacity of up to 3600W. EcoFlow X-Boost technology can support selected compatible appliances requiring up to 2400W.

A total of 11 output ports allows several devices to be connected simultaneously. These include four AC outlets, two fast-charging USB-A ports, two 140W USB-C ports, a regulated car-style power outlet and two DC5521 outputs.

The two USB-C ports support up to 140W per port, making them suitable for compatible laptops, tablets, smartphones, cameras and other USB-C Power Delivery devices.

Dual solar inputs support a combined maximum of 1000W, with up to 500W available through each input. Under suitable conditions and with an appropriately configured solar array, the battery can recharge from 0% to 100% in approximately 70 minutes.

EcoFlow X-Stream charging provides up to 1500W AC input, allowing a complete AC recharge in approximately 56 minutes under suitable operating conditions.

For backup applications, the DELTA 3 Plus provides an automatic transfer time of less than 10ms. This helps supported computers, networking devices and other compatible equipment continue operating during an interruption to the mains supply.

The DELTA 3 Plus can be monitored and configured through the EcoFlow app using Wi-Fi or Bluetooth. Available functions include power monitoring, charging-speed adjustment, output control and supported energy-management features.

Specifications

Output Ports

The EcoFlow DELTA 3 Plus provides 11 outputs:

• 4 × AC outlets
• 2 × USB-A fast-charging ports
• 2 × 140W USB-C ports
• 1 × 12V car-style power outlet
• 2 × DC5521 outputs

The combined continuous AC load must not exceed 1800W during normal operation.

The two 140W USB-C ports require compatible USB-C cables and connected devices to achieve their maximum charging output.

Charging Options

The DELTA 3 Plus supports several charging methods:

• AC wall charging
• Solar charging
• Standard vehicle-socket charging
• EcoFlow Alternator Charger
• Compatible generator charging
• Combined AC and solar charging

AC Charging

EcoFlow X-Stream charging supports up to 1500W AC input and can recharge the battery from 0% to 100% in approximately 56 minutes.

Solar Charging

The two independent solar inputs each support:

• 11–60V input
• Up to 15A
• Up to 500W

The maximum combined solar input is 1000W.

Solar panels and charging cables must be configured so that the open-circuit voltage and current remain within the supported limits of each input.

Vehicle Charging

Standard charging from a vehicle cigarette-lighter socket supports up to 12V and 8A.

Charging at up to 800W requires a compatible EcoFlow Alternator Charger and suitable vehicle installation.

Backup Power and UPS Function

The DELTA 3 Plus provides an automatic transfer time of less than 10ms when connected correctly for backup operation.

This makes it suitable for many compatible devices, including:

• Desktop computers
• Monitors
• Wi-Fi routers
• Network switches
• NAS equipment
• Security systems
• Entertainment equipment

Equipment requiring a certified online or zero-transfer UPS should be connected to a dedicated UPS designed for that requirement.

Expandable Capacity

The DELTA 3 Plus can be expanded from its standard 1024Wh capacity to as much as 5kWh.

Compatible EcoFlow extra batteries include:

• EcoFlow DELTA 3 Smart Extra Battery
• EcoFlow DELTA 2 Smart Extra Battery
• EcoFlow DELTA 2 Max Smart Extra Battery
• EcoFlow DELTA Pro 3 Smart Extra Battery

Compatible extra batteries and the required connection equipment are sold separately.

EcoFlow App

The EcoFlow app provides compatible mobile devices with access to features such as:

• Input and output monitoring
• Remaining-runtime estimates
• Charging-speed adjustment
• AC and DC output control
• Battery-level monitoring
• Firmware updates
• Time-of-use settings
• Storm-warning support
• Energy-management options

Available features may depend on the installed firmware and app version.

Compatibility

The DELTA 3 Plus supports compatible electrical devices with a combined continuous AC requirement of up to 1800W.

X-Boost may allow selected resistive appliances to operate at higher rated power levels, but it does not increase the unit’s normal 1800W continuous output rating. X-Boost may reduce the operating voltage and is not suitable for every appliance.

Connected solar panels must remain within the following limits for each input:

• Maximum open-circuit voltage: 60V
• Maximum current: 15A
• Maximum input power: 500W

The combined solar-input limit is 1000W.

Solar panels, solar charging cables, smart extra batteries, alternator chargers and other optional accessories are sold separately unless specifically included in a bundle.

The DELTA 3 Plus must not be connected directly to a building’s fixed electrical wiring or distribution board without an approved transfer system installed by a suitably qualified electrician.

Sustainability

The LiFePO4 battery is rated to retain at least 80% of its original capacity after 4,000 charge cycles, supporting a longer service life than portable power stations using shorter-life battery chemistries.

Solar input of up to 1000W allows the power station to be recharged using compatible solar panels without consuming fuel during charging.

Battery operation produces no direct exhaust fumes, making the unit suitable for indoor use when operated according to EcoFlow’s safety instructions.
