Does Advanced install DC optimizers to take care of the shading loss issues? One per panel should cut down on shading effects I would think.

If you are planning to do all that mod,

I would have bought a Winnebago ERA.

The interior is far better than RT.
The price is good. (the street price is 25%~30% below MSRP)

The best part is, it has an inexpensive low-tech AGM battery/solar system.

ie. you can rip them all out, and throw them away without feeling any pain.

With the money you saved on the initial price, you could afford to hire a Li/solar specialist to design and build a system of your dream. And the total price will still be cheaper than the long suffering RT warp drive.


Just my 2 cents
YMMV

Yes. My three solar panels are each zoned in half so that partial shade will not effect the whole panels performance. But even if you could do that, and I doubt, but don't know, that Roadtrek does it you would still trade shade from the upright panels that are optimized for the sun.

Each panel in turn on my Advanced RV has its own MPPT controller. I don't know what you mean by DC optimizers.

Roadtrek has maximized the available roof area with 600 watts. They used to get more by eliminating the rooftop air conditioner with a split system but seemingly abandoned that effort. Advanced RV built a 1200 watt assembly for one customer that was built on a structural platform above all the rooftop equipment. That was one of a kind.

That's disappointing. If ARV can't improve on the traditional deafening overhead AC yet, it's probably not possible or at least the tradeoffs don't make sense for most customers.

I have seen one of these in action, very quiet but 230V, I hope Truma will decide to bring it to NA. Onan 2500 LPG should have enough oomph to start. https://www.truma.com/int/en/air-con...ng-systems.php

What may be the latest but not so greatest is the battery charging capacity which was originally designed for a 200 AH battery which is no longer offered. So, for battery capacities ranging from 400 AH to 1600 AH, you are going to get the same charge capacity from both the Nations alternator and the shore side battery charger. Consequently. the alternator will be delivering pedal to the metal for an extended period compared to the typically supplied 400 AH setup and with a discharged 1600 AH warp core, the shore side charger is going to run full tilt for quite a while to provide a full recharge.

The rule of thumb we were told is 45-60 mins per 200AH battery while driving to charge them from 20% to 100%. So 8 hours of driving to fill em up is what we're expecting.

I think having a charge controller per panel as you have accomplishes the same thing as having DC optimizers.

My understanding is that RT offers the undermount A/C for warp core models so that the A/C doesn't shade the panels up top and they can fit 600W up there.

Do you have to remember to turn on all 8 modules before driving if you want them to charge or is that automatically controlled? If not automatic, if it is only a 2 hour drive how many modules would you turn on? Do you have to keep track of which modules were used last? Will you have some sort of usage rotation in place so that the banks get somewhat equal use?

Then I guess when you stop driving you have to remember to turn some modules off.

.

Whoever came up with this "Warp Drive" marketing moniker should get a medal.

The more questions you ask, the more interesting it gets.
