Towed Prius V as DC generator?

Haven’t been active on here much lately, but have a project that might be interesting. Long story short, we’re converting a school bus to live in full time and I’m designing a large solar / battery system for off grid living. I’ll likely be selling my trusty old 2005 Gen II, but we’ll be towing our 2017 Prius V behind the bus for local driving.

Here’s more info on the electrical system:
Mobile 24kWh Leaf Battery, 3.6kW Solar Build

And more on the bus conversion:

As a backup to our solar array, I’m planning to put a tap on the HV battery of the V and run it into our solar charge controller. I’m planning to use the “Enginer” attach point after the contractors / Hall effect sensors and set the charge controller so it hopefully will keep the draw below the point where the Prius freaks out.

Here’s the charge controller I’m using:
TriStar MPPT 600V - Morningstar Corporation

I’ve got the big version with GFPD and DC transfer switch, but I’ve rewired the transfer switch for 2 in 1 out rather than the stock 1 in 2 out. That way I can use it to select the input to the charge controller between solar or Prius.

Anyone know if the access to the HV terminals on the 2017 V is similar to what’s shown in the Gen 3 Enginer installation manual?

I have a full 2012 Nissan Leaf pack on board, about 16kWh usable capacity. Primarily it will charge from solar (12x300w=3600w), but with this setup I should be able to use the Prius as a generator to recharge in emergencies.
