Operating the DELTA 3 Plus

Front Panel Overview:

• AC Power Outputs: Six 120V outlets for standard appliances. The unit provides 1800W continuous power and 3600W surge power.
• USB-C Ports: Two 140W USB-C ports for fast charging compatible devices.
• USB-A Ports: Two fast-charge USB-A ports for various devices.
• Display Screen: Provides real-time information including input power, output power, remaining run time, battery percentage, and other host information. The display is visible even in direct sunlight.

Rear Panel Overview:

• 12V DC Output: Standard 12V car port for DC appliances.
• Barrel Plug Adapters: Additional ports for 12V DC devices.
• Solar/Car Input Ports: Two 15A max/500W per port for solar panel or car charging.
• Extra Battery Port: Allows connection of additional DELTA 3 series or DELTA Pro 3/DELTA 2 Max battery packs to expand capacity up to 5kWh.
• AC Charge Input: For connecting the AC charging cable from a wall outlet.

Advanced Features:

• X-Boost Feature: Accessible via the EcoFlow app, X-Boost allows the unit to power devices requiring up to 2700W. Note that this feature reduces the output voltage, which may not be suitable for all appliances.
• Uninterrupted Power Supply (UPS): When plugged into a wall outlet, the DELTA 3 Plus can act as a UPS. If grid power is lost, the unit automatically switches to battery power within 10 milliseconds, ensuring continuous operation for connected devices like security cameras or internet routers. The unit can be configured via the app to automatically resume AC output when grid power returns.
• Quiet Operation: The unit features efficient cooling fans that operate at a nearly silent 30 dB below 600W, blending seamlessly with ambient noise.

Manage energy and switch to solar-only charging as needed via the EcoFlow app, which also provides UPS alerts and savings modes.

The DELTA 3 Plus offers powerful performance, powering 99% of appliances with X-Boost (up to 2700W output), while operating at a nearly silent 30 dB below 600W.

The compact design of the DELTA 3 Plus allows it to power up to 13 devices simultaneously, being 5% smaller than the DELTA 2 and comparable to a microwave.

Maintenance

To ensure the longevity and optimal performance of your EF ECOFLOW DELTA 3 Plus Solar Generator, follow these maintenance guidelines:

• Regular Cleaning: Keep the unit clean and free from dust and debris, especially around the cooling vents, to ensure proper airflow and prevent overheating.
• Battery Health: For LiFePO4 batteries, it is generally recommended to keep the battery charge between 20% and 80% for daily use to maximize cycle life. For long-term storage, charge the unit to about 50% and recharge every 3-6 months.
