- Product Introduction
In terms of parameters, compared with the previous generation products, DELTA 3000 Gen4 and DELTA 3800 Gen4 are mainly improved in weight and PV charging power, with specific performances as follows: 1. Reduced weight but unchanged capacity DELTA 3000 Gen4 weighs about 26 kg (low-voltage version: 26 kg; high-voltage version: 25.6 kg), about 20% lighter than DELTA 3 Ultra DELTA 3800 Gen4 has a capacity increased to 3763 Wh and weighs only about 30.6 kg (low-voltage version: 30.6 kg; high-voltage version: 30.1 kg), about 15 kg lighter than Delta Pro (about 45 kg) 2. Increased PV input power Delta 3 Ultra: 800W per channel Delta 3 Ultra Plus: 800W per channel for two channels, totaling 1600W DELTA 3000 Gen4: 1000W per channel DELTA 3800 Gen4: 1000W per channel for two channels, totaling 2000W 3. Optimized mobility If you have frequent mobility needs, you can separately purchase the EcoFlow DELTA Series Folding Transport Cart for convenient carrying.
All supported; X-Stream: 1. US/CA: 1,800W, 15A 2. EU/UK/AU/ZA: 2,400W, 10A. Refer to the user manual for X-Boost power in each region. Note: X-Boost is not available when the device is connected to AC input (e.g. when the power supply is charging or in bypass mode). Bypass mode: The device automatically enables bypass mode when charging and discharging simultaneously (via AC input and output ports).
In bypass mode (charging and discharging simultaneously), when the load power is greater than the mains input power, the battery inverter output and the mains supply power to the load together.
DELTA 3800 Gen4 can connect up to 2 extra batteries via the EcoFlow Smart Extra Battery Expansion Adapter. Suggested placement: Delta 3 Max Plus Extra Battery: Can be stacked directly on top of the main unit Delta Pro 3 Extra Battery: It is recommended to stack the two extra batteries and place them next to the main unit Safety reminder: When stacking, please ensure the bottom bearing surface is flat and stable, reserve sufficient heat dissipation space, and avoid blocking the equipment's ventilation vents.
It is recommended to use at altitudes below 3000 meters.
The DELTA 3800 Gen4 is equipped with an Extra Battery Port, which can connect up to two additional battery packs via the EcoFlow Smart Extra Battery Expansion Adapter.
The switching time of the device is <10ms UPS; the device does not support HID communication.
Fridge Runtime Boost™ supports runtime extension for one AC compressor-based cooling appliance at a time, such as a refrigerator, freezer, or wine cooler. Do not connect multiple cooling appliances or use them alongside other AC appliances, as this may affect power supply stability.
3-year basic warranty + 2-year extended warranty complimentary upon registration
Under the conditions of 1 meter away from the device and an ambient temperature of 25°C, the noise levels corresponding to different power gears are as follows: Low-power operation (≤600W): ≤30 dB Medium-power operation (≤1800W): ≤40 dB Full-power operation (≤3600W): ≤50 dB 30 decibels (dB) is approximately the volume of a soft conversation, or the ambient volume in a quiet library or office; a sound level of 30 decibels is generally considered a comfortable background noise level.
It will automatically turn on when charged, and charging while the device is powered off is not supported.
A full charge and full discharge cycle is sufficient to complete battery calibration.
Ensure that the AC output is turned off, then press and hold the button for 10 seconds to switch the AC frequency.
The charging logic of the main unit and the power pack is to first charge the one with lower voltage, and charge both simultaneously when their voltages are consistent. For discharging, the one with higher voltage will be discharged first, and both the main unit and the power pack will discharge at the same time once their voltages are the same.
The battery cell of the device is LFP (Lithium Iron Phosphate Battery).
Laboratory tested to withstand 5000 insertion and removal cycles and 10000 keystroke operations.
Prohibited from being carried onto aircraft; for details on whether it can be carried on high-speed trains and cruise ships, please consult the relevant department or the customer service hotline of the corresponding transportation provider.
For stability reasons, it is not recommended to use this as a power supply method for first-aid equipment (such as ventilators).
Normally, the device will generate certain background noise (from fan operation and current flow) during normal operation. However, if there is no improper use but the noise increases significantly, or abnormal sounds such as sharp whistling, knocking or rubbing sounds occur, this may indicate that there is a problem with the device. You can record a video of the fault and feed it back to us, and we will assist you in verifying and handling the issue.
