FAQ

Can EcoFlow RIVER 3 Plus be connected to multiple extra batteries?

No, it can only connect to one extra battery.

What is the relationship between EcoFlow RIVER 3 Max, RIVER 3 Max Plus, and RIVER 3 Plus?

EcoFlow RIVER 3 Max consists of EcoFlow RIVER 3 Plus connected to the EcoFlow RIVER 3 Plus Smart Extra Battery EB300 (286Wh). EcoFlow RIVER 3 Max Plus consists of EcoFlow RIVER 3 Plus connected to the EcoFlow RIVER 3 Plus Smart Extra Battery EB600 (572Wh).

Can EcoFlow RIVER 3 Plus Smart Extra Battery charge and discharge independently?

Yes, it supports up to 140W of bidirectional USB-C charging and discharging.

How many solar panels can EcoFlow RIVER 3 / RIVER 3 Plus use, and what is the solar charging power?

You need to check the parameters and configuration of the connected solar panels to ensure the total power is within the acceptable range of the portable power station's specifications. Exceeding these limits could damage the portable power station. Refer to the user manual to confirm the solar input specifications, including: a. voltage range; b. maximum current; c. 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. There are two connection methods: series and parallel. ① In series, the voltage adds up while the current is limited by the panel with the lowest current; ② In parallel, the current adds up while the voltage is limited by the panel with the smallest voltage. (If the portable power station has overcurrent protection, the current will be limited to the device’s maximum input current). EcoFlow RIVER 3 solar input specifications: Voltage range 11~30V, maximum current 8A, maximum power 110W. For 45W solar panels: Series: Maximum 1 panel. Parallel: Maximum 3 panels. For 60W solar panels: Series: Maximum 1 panel. Parallel: Maximum 2 panels. EcoFlow RIVER 3 Plus solar input specifications: Voltage range 11~50V, maximum current 13A, maximum power 220W. For 45W solar panels: Series: Maximum 2 panels. Parallel: Maximum 4 panels. For 60W solar panels: Series: Maximum 2 panels. Parallel: Maximum 3 panels.

Does EcoFlow RIVER 3 / RIVER 3 Plus support simultaneous solar and AC charging?

Yes, the charging priority can be adjusted in the app. 1. By default, AC charging takes priority, but you can change the priority via the app. 2. When both AC and solar inputs are connected, AC charging will take priority. The solar panel will charge at its maximum power, and the AC will supplement any additional power needed to fully charge the battery.
