Questions about this model
How much energy does the RIVER 3 (UPS) store?
The manufacturer lists 245 Wh. Conversion loss and a reserve reduce the energy available to your devices.
How much power can it deliver?
Normal continuous output is 300 W. A short surge figure does not prove that every motor or appliance can start.
Which solar panel can I use?
110 W solar ceiling listed. The complete PV voltage/current envelope and the exact cable path are not verified here; no panel compatibility is inferred.
