Series 12v Chargers ?
Bestconverter ad says, "The PD9100L Series can be wired in parallel to charge at much higher current rates. They can also be wired in series/parallel to charge 36, 48, 60, 72 and higher voltage bat...

BTW I wouldn't bet on 2 different chargers working as expected in series. The chargers are no longer adjusting their charging algorithms based on a battery because each is now seeing a battery and another charger in series. Varying house loads are also a factor.
But try it and it may work OK depending upon the charger designs.
These are single constant voltage but adjustable voltage chargers, so I can make them both 14.8 (or anything else in their pot range (12-15.5v)
I am still amazed at the idea here. Right now I can get 155 amps on my 12v bank with the 55 and 100 ampers in parallel. But that maxes out the Honda 3000. If I can run the 75 and 100 on the 24v bank (same batts re-wired) with the Honda, that is 75 on the 24v bank, same as 150 on the 12v bank? Wow!
That is not slower/longer, so I am still suspicious. :)
With a 24v bank I could run the 24v solar panel with a cheapo 12/24 PWM controller instead of the more expensive MPPT. (Tested that--gets equal or better results--see posts from two years ago or whenever that was)
Would still need a 24v inverter and a 24-12 converter (or put the rig's 12v converter on the 24v inverter.) The big 24v volt inverter is the killer for money, I think.
