Powerful Output, Whisper-Quiet Operation
The DELTA 3 Plus delivers 1800W rated AC output and 3600W surge capacity. With X-Boost technology, it supports compatible appliances up to 2400W, including kettles, hair dryers, ovens, and other heating devices, all while operating at under 30dB at 600W loads, quiet enough to run inside a tent or living room without disrupting sleep.
The pure sine wave inverter delivers stable AC power suitable for sensitive electronics like laptops, NAS servers, and 3D printers. Total connected load must always remain within the rated output of the unit.
4 Ways of Industry-Leading Fast Charging
Perfect for indoors, outdoors, or on the go.
AC Charging
1500W AC input. 0 to 100% in approx. 56 minutes from a standard NZ wall outlet.
Solar Charging
Up to 1000W solar input across 2 MPPT ports. 0 to 100% in approx. 70 minutes.
Car / Alternator Charging
12V car input or up to 800W via the EcoFlow 800W Alternator Charger. 0 to 100% in approx. 1.3 hours.
Multi-Charging
AC and solar combined for the fastest top-up. 0 to 100% in approx. 56 minutes with 1500W combined input.
Portable Dual Battery System for 4WDs and Motorhomes
Pair the DELTA 3 Plus with the EcoFlow 800W Alternator Charger to create a portable dual battery system for your 4WD, motorhome, or campervan. No fixed wiring, no fuss, and full 1024Wh charged in around 1.3 hours of driving. Use it in your vehicle, take it to the campsite, or carry it inside as home backup when you're not on the road.
Reliable Backup with Under 10ms UPS
When grid power drops, the DELTA 3 Plus switches to battery power in under 10ms, keeping desktop computers, laptops, NAS servers, 3D printers, and other sensitive equipment running without interruption. It also supports HID communication with NAS devices, sending a signal before the battery depletes so the server can save data and shut down safely.
30dB Ultra-Quiet Operation
At 600W loads, the DELTA 3 Plus operates at under 30dB, blending into ambient noise. Run a fridge overnight in the lounge, power low-noise overnight equipment such as compatible CPAP machines (where the user has confirmed the power requirements), or work from home during an outage without the constant fan whine of a traditional generator.
EcoFlow App: Smart Energy Management
Monitor real-time battery status, customise charging speed, control output ports remotely, and receive firmware updates over Wi-Fi or Bluetooth. Smart Output Priority technology lets you choose which outputs or connected loads stay powered through the EcoFlow app, helping you extend runtime for the loads that matter most.
Long-Lasting and Durable
Triple protection from the inside out for guaranteed safety.
LFP Battery
Third-gen LiFePO4 cells. 4000 cycles to 80% capacity, up to 10 years of reliable use.
IP65 Battery Pack
Internal battery pack rated IP65 against water splashes and dust. Note: this is not a waterproof rating for the full unit. The power station should still be protected from rain and water exposure.
Advanced BMS
Over 40 protections for current, voltage, temperature, and circuit risks. Thermal runaway protection.
Compact Design
About the size of a small microwave. 5% smaller than DELTA 2, fits in a ute boot or under a desk.
