I suggest you start a new topic, with the word Growatt in the title. Then some Growatt owners and/or experts may be able to help.

Ah, so it's a Growatt. These look superficially like Axperts, so much so that I'm 95% convinced that they started with copies of the Axpert schematics.
But despite their likely origins, Growatts are quite different from Axperts. The few firmwares that I have looked at have some similarities with Axpert firmwares, but are not compatible at all (from distant memory).
My expertise ends with Axperts, and really with 48V models, though some 24V models are close enough that I can help a little. But this 24V Growatt, sorry, I know nothing about them.
However, the sticker says that max charge current is 50A, which (like Axperts) is almost certainly battery-side current (not PV-side current), so you can only get 50 x 25 = 1250W through the solar charge controller. Some of that will be to support loads, so that explains why you never get more than about 1000W of charge power. You still should be able to get a little more than that as reported PV total power.
The other thing is that 1470W of nominal PV power usually only translates to about 80% of that, or 1100-1200W depending on many factors. The main reason is temperature rise of the panels; this reduces the voltage of the cells, so less power is available after a few minutes of sun.
