Understanding Solar Compatibility with the RIVER 2

MPPT Range & Why It Matters

The RIVER 2 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 2'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 2

The RIVER 2 uses a XT60 solar input connector. XT60 is a standard connector shared across many brands. Most third-party panels with XT60 connect directly. 12 of 20 panels require an adapter with this unit.

Frequently Asked Questions

Can I use any solar panel with the EcoFlow RIVER 2?

No. The RIVER 2 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 2 with solar?

With the fastest compatible panel (EcoFlow 110W Solar Panel, 110W delivered), the RIVER 2 (256Wh) charges in approximately 3.3 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 3.7 hours.

Do I need an adapter for solar charging the RIVER 2?

The RIVER 2 uses a XT60 connector. 12 of 20 panels require an adapter. The remaining panels connect directly via XT60.
