Understanding Solar Compatibility with the RIVER 2 Pro
MPPT Range & Why It Matters
The RIVER 2 Pro accepts solar input between 11V and 50V (MPPT range). Panels with Vmp below 11V won't start charging — the MPPT controller can't lock on. Panels with Vmp above 50V may damage the input circuit.
Cold Weather Voltage Safety
We apply a 1.2x safety margin to each panel's open-circuit voltage (Voc) to account for cold temperatures, when solar cells produce higher voltage. The RIVER 2 Pro's maximum input voltage is 50V. Any panel whose Voc x 1.2 exceeds 50V is flagged as a voltage danger. 17 of 20 panels pass this safety check.
Cables & Adapters for the RIVER 2 Pro
The RIVER 2 Pro uses a XT60i solar input connector. This unit uses XT60i — standard XT60 cables limit input to 8A. Use the XT60i cable to unlock 13A. 17 of 20 panels require an adapter with this unit.
Frequently Asked Questions
Can I use any solar panel with the EcoFlow RIVER 2 Pro?
No. The RIVER 2 Pro requires panels with Vmp between 11V and 50V, and cold-weather Voc (Voc x 1.2) under 50V. Of the 20 panels we tested, 16 are fully compatible, 1 work with limitations, and 3 are incompatible.
How long does it take to charge the RIVER 2 Pro with solar?
With the fastest compatible panel (EcoFlow NextGen 220W Bifacial Portable Solar Panel, 220W delivered), the RIVER 2 Pro (768Wh) charges in approximately 5 hours under real-world conditions (70% derate for angle, clouds, and temperature). The slowest compatible option (Jackery SolarSaga 80W Solar Panel) takes approximately 13.7 hours.
Do I need an adapter for solar charging the RIVER 2 Pro?
The RIVER 2 Pro uses a XT60i connector. 17 of 20 panels require an adapter. The remaining panels connect directly via XT60i.
