Well, the solar charger states 50Amps and battery is 24Volts, so Power P=V*I = 24 * 50 = 1200W

For the solar voltage of max 80V you will need to find panels less than 300W (the max Voc for each panel will need to be below 40V) if you want to add 2 panels in series. So it might be better to look at doing only 1 panel per string of more than 400W (their Voc is around 50V and doing them in parallel if you can find smaller panels.

Good luck

It may be a PWM model, in which case 2 panels in series doesn't make sense (the panels will mostly be limited to battery voltage).

I note that it has a 16 character serial number, Axperts usually have 14 characters. The first 4 digits (6399) are very different (all Axperts I've seen start with 92). It's PF0.8, when all modern Axperts (as far as I know) are PF1.0. Finally, there is no date sticker over the nearest screw. So this appears to be a clone.
