A cell that says unknown was not on the cited page, or the cited pages disagreed enough that picking one number would hide the disagreement.

Other figures from the same sources

  • Solar input window. 11–50 V, 13 A, 220 W max
  • AC charge input. 100–120 V, 660 W max
  • X-Boost. The page says X-Boost up to 1000 W. That matches the surge figure in the spec block and is not stored as additional continuous watts.

Where do the source pages disagree?

Weight. A heading says lightweight at only 13.2 lb. The spec block says approximately 13.4 lb. The recorded weight follows the spec block.
What’s in the box. The what’s-in-the-box list on this Max page names a RIVER 2 Pro as item 1. The spec block is titled RIVER 2 Max. This record uses the Max spec block and does not mix in a separate Pro model.
Regular price label. The page shows a regular price of $299.00 and also a line that reads Regular price USD $289.00. Both labels were visible in the captured text, so the regular-price label is inconsistent.

Is this a good price?

Price tracking starts when authorized retailer feeds are connected.

No retailer offer is stored for this model. A price printed on a manufacturer page is a snapshot of that page, not a market comparison. When offers are stored, BlackoutSmart will describe the low in its own file as the lowest observed since the date of the earliest stored observation.

MSRP

unknown. None of the pages cited for this model labeled a figure as MSRP. A “regular price” or a second displayed number is not recorded as MSRP.

What the manufacturer page showed

  • $289.00 — Sale price shown on the US product page Retrieved 2026-11-07.
  • $299.00 — Regular price shown on the US product page. The page did not call this MSRP. Retrieved 2026-11-07.

These are snapshots of a page on that date. BlackoutSmart does not subtract two displayed figures and does not call the gap savings.
