You can select an extra battery based on the required capacity. The XT150 connection cable is used to connect the XT150 port on the back of the device. The maximum expandable capacity is 5024Wh (the device itself has 1024Wh with only one extra battery port, allowing connection to the largest extra battery, EcoFlow DELTA Pro 3 Extra Battery (4000Wh), expanding the capacity to 5024Wh).
EcoFlow DELTA 3 or DELTA 3 Plus can be charged through the AC input port, XT60 input port, and XT150 port. It supports connection to multiple input sources simultaneously, with the following charging priority: EcoFlow Microinverter (via XT150 port) > Solar panel (via XT60 port) > AC (via AC input port, including grid power and generators (Smart Generator 3000 (Dual Fuel)) > EcoFlow Smart Generator (input via XT150 port (Smart Generator (Dual Fuel), Smart Generator 4000 (Dual Fuel)) > EcoFlow Alternator Charger (via XT150 port)
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.
Once the local electricity rates are set up in the EcoFlow app, enabling TOU mode allows the system to consider factors such as electricity price differences, optimal charging times, and solar charging to fully charge the device.
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.
