FAQ

How many solar panels can be used with EcoFlow DELTA 3 or DELTA 3 Plus, and what is the solar charging power?

It is necessary to confirm the parameters and combination method of the connected solar panels. The maximum power of the solar panels must fall within the specified range of the extra battery. Exceeding the limit could damage the extra battery, making it unusable. First, check the user manual to determine the solar input specifications of the extra battery, including: ① voltage range, ② maximum current, and ③ maximum power. The combination of solar panels must meet the following conditions: 1. Voltage: The open-circuit voltage of the solar panel must fall within the voltage range of the portable power station ①; 2. Current: The maximum current of the solar panels ≤ the maximum current of the portable power station ②; 3. Power: The maximum power of the solar panels ≤ the maximum power of the portable power station ③. All three conditions must be met; exceeding any one of them means the solar panels cannot be used. Combination methods: ① There are two types of combinations: series and parallel; ② In series, the voltage adds up while the current is limited by the panel with the lowest current; In parallel, the current adds up while the voltage is limited by the panel with the lowest voltage. (If the portable power station has overcurrent protection, the input current will be limited to the portable power station's maximum current.) Example: Can EcoFlow DELTA 3 be used with two EcoFlow 400W Rigid Solar Panels? First, check the user manuals for EcoFlow DELTA 3 and the solar panel: ① EcoFlow DELTA 3 solar input specifications: Voltage range: 11-60V, Maximum current: 15A, Maximum power: 500W. ② Open-circuit voltage of solar panel: 37.1V, Maximum operating current: 12.9A; [Use in series] Open-circuit voltage: 37.1 x 2 = 74.2V; Current: 12.9A; Power: 74.2 x 12.9 = 957.18W, which exceeds the 500W input power limit of the portable power station, so it cannot be used. [Use in parallel] Open-circuit voltage: 37.1V; Current: 12.9 x 2 = 25.8A ＞ 15A, which exceeds the 15A current limit of the portable power station, so it cannot be used.

Will EcoFlow DELTA 3 or DELTA 3 Plus automatically turn on when there is grid or solar charging input while the device is off?

Yes, the device will automatically turn on when there is an input.

Does EcoFlow DELTA 3 or DELTA 3 Plus support bypass mode output?

Yes, bypass mode output is supported, and it is enabled by default. It can also be disabled in the app. If the grid power is unstable and may cause improper functioning or damage to appliances, you can enable this setting in the EcoFlow app for appliances that require high-quality power output. For example, this mode allows you to use only the AC output power from the extra battery for speakers.

Is the device grounded?

Yes, the AC output and the internal system of the device are grounded. If the device's AC input is connected to the grid, it will share the same ground as the grid power.

What are the differences and upgrades between EcoFlow DELTA 3 or DELTA 3 Plus and the previous generation?

Compared to EcoFlow DELTA 2: 1. The PV input has been upgraded from 1 input to 2 inputs (EcoFlow DELTA 3 Plus has 2 inputs, and DELTA 3 still has 1 input). 2. The charging speed has been improved from full charge in 80 min to full charge in 56 min. 3. The waterproof rating has been upgraded from IP20 for the whole product to IP20 for the whole product and IP65 for the battery cells. 4. The EPS switchover time has been improved from 30 ms to 10 ms UPS. 5. The noise level has been reduced from <35dB at 600W and <45dB at 1200W within half a meter to <30dB at 600W and <40dB at 1200W. 6. It can now perform wireless hybrid operation with a 1.8KW generator (EcoFlow Smart Generator 3000 (Dual Fuel)) and supports automatic start-stop with just an AC cable. 7. Added a low-light detection circuit. 8. The extra battery port has been moved from the side to the back, supporting stacking and placement against a wall, and is compatible with D2, D2M, DP3, and D3 extra batteries.
