Understanding Solar Compatibility with the RIVER 3
MPPT Range & Why It Matters
The RIVER 3 accepts solar input between 11V and 30V (MPPT range). Panels with Vmp below 11V won't start charging — the MPPT controller can't lock on. Panels with Vmp above 30V 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 3's maximum input voltage is 30V. Any panel whose Voc x 1.2 exceeds 30V is flagged as a voltage danger. 12 of 20 panels pass this safety check.
Cables & Adapters for the RIVER 3
The RIVER 3 uses a XT60i solar input connector. This unit uses XT60i — standard XT60 cables limit input to 8A. Use the XT60i cable to unlock 8A. 12 of 20 panels require an adapter with this unit.
Frequently Asked Questions
Can I use any solar panel with the EcoFlow RIVER 3?
No. The RIVER 3 requires panels with Vmp between 11V and 30V, and cold-weather Voc (Voc x 1.2) under 30V. Of the 20 panels we tested, 5 are fully compatible, 7 work with limitations, and 8 are incompatible.
How long does it take to charge the RIVER 3 with solar?
With the fastest compatible panel (EcoFlow 110W Solar Panel, 110W delivered), the RIVER 3 (245Wh) charges in approximately 3.2 hours under real-world conditions (70% derate for angle, clouds, and temperature). The slowest compatible option (Goal Zero Boulder 100 Briefcase Solar Panel) takes approximately 3.5 hours.
Do I need an adapter for solar charging the RIVER 3?
The RIVER 3 uses a XT60i connector. 12 of 20 panels require an adapter. The remaining panels connect directly via XT60i.
