Critique proposed solar battery upgrade
Currently have a Jayco hybrid (Jayfeather 26L) but moving to a Denali 5th wheel in the spring (2012 DE324LBS). Currently have 4 Trojan T125’s with 600 watts of solar, with a Kisae 2000 watt pure sine...

Lithium is going to seem like a leap. However half your solar is going to be wasted on absorption time with the amps tapering off to nothing with the AGMs....lithium will absorb all the solar you can produce right up to the point of full.
Also as you get into the 1 kW solar zone consider going 24 volts on the main battery and inverter.
Li's are great, but will dent your wallet something fierce. If you can handle the $1000/battery you won't look back. Zero maintenance and much less weight than lead batteries. And way less voltage drop on high-draw appliances.
24 volts or higher is a great idea. You don't need cables the size of your thumb. I'm running 48vdc. Small converter for the coach's 12v supply.
Running higher voltage solar is what I also recommend. Again, smaller wire size and more efficiency. Of course you'll need a controller to handle the input voltage.
