Hello all and thanks for having me.
My question is:
If I'm using a C-tek D250s as a DC to DC charger can I connect a C-tek MXS-10 to the solar input of the 250? The MXS is a 240 volt to DC charger at 10 amp max. My thinking is the 250 would see this 10 amps at 14.7volt as a solar panel and treat it as one. Any thought would be great..

What would you gain by doing so, the C-tek MXS-10 should charge the battery fine, if you run it through 250 your not going to acheive anything, with conversion losses in the 250 you'll be worse off?

Why not just permanently wire the charger to the battery, if you wish to use the charger for other things then you could connect it through and Anderson plug so that can easily remove it if required?

I doubt it will work.

If it was going to work at all, the MXS would have to be in supply mode. In charger mode the output circuit and logic will be looking for the characteristics of a connected battery. The 250s will not look like a battery. Therefore I think the MXS will not respond. One or both devices might let some smoke escape :-(

If you put the MXS into supply mode then it won't be looking for a battery. But the voltage will be down, I dunno, 12.7 or 13.3 or so, and that may be too low for the solar input of the 250s to respond.

But why not just connect the MXS direct to the battery? Even if your premise did work, the output of the 250s would be limited by the input of the MXS of 10 amps, less losses, so you would gain nothing. If mains is available, just connect the MXS direct to the battery.

Cheers

The solar charger (reg) will be looking for about 17v connect to the solar input. So no, it won't work.

If your reason for making the connection is easy access ,connect the charger to the output terminal of the 250 ( bat + )

cool and the charger will just be inert till plugged in to 240, no voltage back up issues? Yes your right its about access mostly. My Toyota is pretty full now and it would be easy just to plug in from outside and let it charge. Thanks

just an update to my question about 240 volt charger inline with c-tek DC to DC charger. If every thing else fails read the manual. lol
