Questions about this model
How much energy does the RIVER 3 Max Plus store?
The manufacturer lists 858 Wh. Conversion loss and a reserve reduce the energy available to your devices.

Normal continuous output is 600 W. A short surge figure does not prove that every motor or appliance can start.
Which solar panel can I use?
The documented input range is 11–55 V, up to 220 W total. Also check current, cold open-circuit voltage, connector and polarity.
