Oh they absolutely do! My only point is that grid supply must equal grid demand. There are many ways to achieve this, as folks here have pointed out.
Throttling power generation (turning off/disconnecting PV from grid for example), and storage (chemical, heat, or hydro battery) are all established technologies, they just need to be implemented properly to avoid supply/demand mismatch.
Why wouldn’t batteries work?
