How to Arrange for 24 Volt with 8 200 Watt Solar panels

[RollinCabin]

Hi, and thanks for your help!
I went ahead and bought parts for my system before knowing what I was doing. I need advice on how to connect 1600 Watts of poer to my batteries. But I have an MPPT charger controler that would require a 24 Volt setup and an inverter that needs batteries run in 12 volts. Feel free to leave comments that mock this as long as you give some good advice as well. I was thinking maybe I need to connect 4 of the 200 watt panels to two different charge controllers? Ir should I eat it and buy a new inverter? I really want to use all of the panels to run some AC so I can leave my dog in the bus without him roasting!

2S4P if shading is a concern
4S2P is shading isn't a concern.

Make sure you individually charge each 12V to full AND then again in parallel @12V preferably holding at 14.4V for 2 hours before placing them in series. The 12V will come at a reduced state of charge, and it is very common that they will take different amounts of charge to get to full. This can result in one of the 12V BMs cutting out because a cell in one of the 12V has hit limit.

The MPPT will work fine at 12V, but you won't be able to capture all the PV output.

If you want to go 24V, you need a 24V inverter. Ditch the 12V inverter.

Lastly, given that you indicate you want to run A/C, this is likely a very minimal setup depending on the A/C unit and the heat load.

Say what?

Your mppt will handle 12v at limited capacity. Options - sell it, buy a 2nd one, upgrade to a better mppt
You have a 12v inverter... You'll be pulling some serious current trying to run and AC.
Make sure you have quality connections and sufficient wiring. Recommend upgrading to 24v.
Your battery link is fubar for me. I hope they are 12v if you plan to keep the inverter I wish they were 24v if you plan to upgrade the inverter, unless the BMS's support series.

The reply from @sunshine_eggo is better than mine.

Based on the info provided ,If I cared about my dog I would go out tomorrow and buy the right inverter, and then I would be carefull before trusting it with the dogs health or life.

..depending on the temps involved he may not survive being part of the learning curve testing that solar generally takes to get it running solid.…especially concerning A/C usage…

there will be plenty of time later to find good uses for anything you may have bought that wasn’t correct for the present mission.
Take care of Bowser…..!
