Evie,
The Slide-On manufacturer is maybe confusing you.
The Ctek Multi XS 15000 only has a 240vac input source. A very good charger all the same but it would be wired to a 240vac source.
The Slide-On camper would have a 240v caravan style external 15 amp weather proof "plug" and probably wired inside to the input of the charger. There would also be one or more 240v power outlets with an RCD safety device in the circuit for protection against shock.
This 240v circuit would only be able to be connected up via a 15 amp lead, or a 10 amp to 15 amp converter such as the "Ampfibian", or similar device.
No Ctek charger to my knowledge has a 12 volt input, other than the D250S dc-dc charger.
Perhaps what they were intimating is that they could provide an alternative circuit allowing the alternator circuit to be connected direct to the battery bank. This is certainly possible without the Ctek D250S dual, providing heavy duty cable was used to limit voltage drop.
The success of this connection would be largely dependent on the output characteristics of your alternator. Some late model vehicles have a restricted output.
With this circuit, a solar panel could be connected to the cable via an Anderson connector or similar and rely on the smarts of the solar controller on the panel.
The advantage of the D250S dual controller is that any lower level voltage will be boosted to an optimum level for efficient and effective charging, with a current of 20 amps, regardless of whether the input is from the alternator or the solar panel.
