Reliable power wherever your business needs it

The DELTA 3 Plus brings substantial portable power into a relatively compact 12.5kg platform.

Its 1024Wh LFP battery can power a broad range of professional devices while its 1800W AC inverter supports equipment ranging from laptops and monitors to production gear and selected larger appliances.

For businesses requiring temporary backup power, the <10ms UPS switching capability provides an additional level of continuity for compatible equipment.

Solar, vehicle and AC charging options make the platform suitable both inside the office and in mobile environments.

1024Wh LFP battery

DELTA 3 Plus uses lithium iron phosphate battery chemistry designed for long-term repeated use.

EcoFlow rates the battery for approximately 4,000 cycles before reaching 80% or more of its original capacity.

This makes it particularly relevant to businesses expecting frequent charging and discharging rather than occasional recreational use.

1800W professional AC output

DELTA 3 Plus provides up to 1800W continuous AC output with a 3600W surge rating.

This allows it to support many common business and production devices.

X-Boost technology can support selected higher-powered resistive devices beyond the normal inverter rating.

Always verify the actual operating and startup power requirements of equipment before connecting it.

Fast UPS response

Backup transition in under 10ms

The built-in UPS functionality can switch to battery power in under 10 milliseconds under supported conditions.

This can make the DELTA 3 Plus useful for selected:

Workstations
Networking equipment
NAS devices
Point-of-sale systems
Production computers
Communication equipment

Suitability depends on the connected equipment and required backup standard. Critical infrastructure should be assessed individually.
