The EcoFlow RIVER 2 Max accepts 11–50 V and up to 13.0 A on its solar input, and converts at most 220 W. The upper voltage is an absolute limit: open-circuit voltage above it damages the port, and panels make more voltage the colder it gets.
27 of the panels in the table fit one more in series at 25 °C than on a Denver record night. For example two ECO-WORTHY 130W 18BB Flexible Solar Panel (GW-L02AM130W18V-1) panels read 49.0 V on the label and 59.6 V at −31.7 °C: wired "in series like in the video", the string crosses the limit.
Parallel wiring is not free either. Two Rich Solar MEGA 200 (RS-M200) panels in parallel short-circuit at 23.2 A against a 13.0 A input; the station limits the current and roughly 44 % of their peak power goes unused. Charging from empty in full sun takes about 2.8 hours from 200 W of panels and 2.3 hours from 400 W, because the station never converts more than 220 W. Behind a cloud or in winter it takes several days.

How this page was computed
A wiring is safe when open-circuit voltage at the temperature stays at or below the input maximum and stays at or above the start voltage. Current above the input limit is clipped, not dangerous.
- Manufacturer specifications verified 2026-09-15
- Panel datasheets and the CEC list 83 panels
- Denver record low: NOAA NCEI GHCN-Daily −31.7 °C
The formulas are the same open engine the checker runs; the methodology page lists every constant.
These results are for reference. Wiring must be installed by a qualified electrician. Mobile installations follow ABYC E-11; stationary ones NEC 690/706.
