Product Description

The EcoFlow DELTA Pro 3 is a 4096Wh high-capacity portable power station designed to provide reliable backup power at home, at work or away from mains electricity.

This listing is for the South African Plug version with 4 South African AC outlets: 2 × SANS 164 Type N and 2 × SANS 164 Type M.

4000W High Output

The DELTA Pro 3 delivers 4000W continuous pure sine wave AC output, allowing it to power a wide range of compatible household appliances, electronics, business equipment and outdoor devices.

It also supports up to 8000W surge output for compatible startup loads.

EcoFlow X-Boost technology supports selected compatible appliances rated up to 6000W.

X-Boost does not increase the normal continuous AC output beyond 4000W and may not be suitable for every appliance.

Fast AC Charging

EcoFlow fast-charging technology allows the DELTA Pro 3 to recharge quickly from mains power.

The unit supports up to 2900W AC charging input.

Under supported charging conditions, the DELTA Pro 3 can recharge from 0–80% in approximately 50 minutes.

Actual charging time depends on input power, battery level, temperature and operating conditions.

Solar Charging

For renewable and off-grid charging, the DELTA Pro 3 supports up to 2600W solar input across two PV input ports.

High-voltage PV input supports 30–150V, 15A max and 1600W max.

Low-voltage PV input supports 11–60V, 20A max and 1000W max.

Compatible solar panels and connection equipment must remain within the DELTA Pro 3 solar-input limits.

Solar panels and solar charging accessories are sold separately unless included as part of a specific bundle.

10ms UPS Backup

The DELTA Pro 3 provides 10ms automatic UPS switchover, allowing compatible equipment to transfer rapidly to battery power when mains electricity is interrupted.

This makes it suitable for compatible equipment such as:

Home-office equipment
Computers
Wi-Fi and fibre equipment
Networking equipment
NAS systems
Selected servers
Security equipment
Communication equipment
Other suitable electronics

Important: The DELTA Pro 3 is not a zero-transfer-time online UPS.

Connected equipment must be capable of tolerating a transfer time of approximately 10 milliseconds.

Always check the backup-power requirements of sensitive or critical equipment before use.

Long-Life LFP Battery

The DELTA Pro 3 uses LFP / LiFePO₄ battery chemistry.

The battery is rated to maintain more than 80% state of health after 4000 cycles under specified test conditions.

The intelligent battery management system monitors battery status, temperature and other operating conditions to support safe and stable operation.

Actual battery lifespan will depend on usage patterns, charging behaviour, temperature and operating conditions.

Expandable Capacity

The DELTA Pro 3 starts with 4096Wh capacity.

For longer runtime, it supports compatible EcoFlow extra battery expansion options and can expand up to 12kWh.

Compatible EcoFlow products may require the latest firmware.

Extra batteries, adapters and connection cables are sold separately unless included as part of a specific bundle.

Quiet Operation

EcoFlow lists quiet operation from approximately 30dB under specified conditions.

Noise levels will increase depending on load, charging rate, ambient temperature and cooling requirements.
