Here’s the [link|https://www.dpipower.com/MNUL/General_Chargers.pdf|charger manual] that may be of some help.
The model number you quoted is listed on the cover page and there is a schematic on p.13.
There is no schematic for the pcb itself only where the AC is connected to the pcb board and on what terminals the DC output is.

I don’t think that it is as simple as injecting DC on the pcb and using the charger controls as the charger may limit the AC input supply to affect how much DC is being supplied to the battery. The schematic indicates that the transformer has two outputs into the charger so it may use both or only one as required, I don’t know

Maybe you can disconnect the wires from P5 (+ve) and P4 (-ve) on the pcb and connect your solar DC supply to an [link|https://www.cleanenergyreviews.info/blog/mppt-solar-charge-controllers|MPPT controller] and then connect it directly to the +/-ve wires that were previously on the pcb.

If not a controller you would need something (heavy duty diode?) to prevent the batteries from discharging back into the solar panel when the battery voltage exceeded the solar panel voltage e.g. when the clouds obscured the sun etc

Looks like you connect the DC to P5 (+ve) and P4 (-ve) on the pcb or better just remove the wires that are on those terminals and connect your DC supply to them directly and correctly polarity wise.
