If I was using the Diode solution, I'd stick with a standard diode, schottky diodes have about half the volt drop (0.35V), I guess that's why they use them here.

So If I use the DC50s I wouldn't need the victron MPPT either?Renogy DC50s

Victron make awesome kit. . .
But the Orion DC-DC (specifically) is only 30A and gets red hot. . . . and is huge, and has no voltage/current monitoring.
++++++++++
so for a DC-DC charger, the Renogy DC50s beats it. - IMHO.
and beats the ctek D250SE
and beats the redarc BCDC1250D
not tested the Sterling ( and dont want to .. to large, fans, ppl showing it failing )
++++++++++
why?
APP based monitoring via BT2
Programmable charge profiles,
Programmable current limiter
Built in MPPT
Built in starter top-up from solar,
stays cool under 80% load.
you could use the DC50s MPPT for solar yes.
but when you have any solar connected to the unit it limits each input to 25A + 25A . ( from the 50A possible )
so if you want more than 25A DC-DC charge - then fit a switch on the solar, or just use a separate MPPT ( ie the victron)
....
Got it
FYI . .
the solar VOC max input on the DC50s is 25V ( so you need to connect panels in parallel - up to 330w / 660W )

Right, I was thinking of leaving the CTEK solar input for the extra fold out panels and using the victron smart Mppt for the 160w panel on the roof.
will this work ok?
Also, what size battery protect should I get? I'm running a 55L compressor fridge and only a few led lights and some usb chargers, would the 65 amp be enough or get the 100?
