This is what I did with my Grenadier Today.
After going through the forums concerning the dual battery setup, and wanting to add solar charging with out adding another system I decided to try a D250SE. There seems to be a lot of talk about the dual battery configuration, love it or hate it, I got it.
I've installed a RedArc DCDC charger for house batteries in my 1985 FJ60 landcruiser and it worked out well again not wanting to add another system to the Greadier I figured I would give Ctek some love . I'm sure the factory dual battery setup with solar will work fine, even though its not a traditional start/AUX-house battery setup, running a fridge, lighting and charging electronics, a few offgrid days at a time.
For the D250SE I used the Blacksheep mounting plate which worked fine, as mentioned in the forums, it is a tight fit where the temp wire comes out of the D250SE, hitting the seat bracket. I used a 30Amp fuse as recomented by Ctek on the solar feed going into the unit and connected it to an anderson plug on the passanger side, rear battery box. Once in service I confirmed opperation by plugging in a 120watt panel. Simple install, about an hour and a half, a bit expensive due to the cost of the D250SE. Worth it? Time will tell.
