My Redarc 50amp just senses the voltage increase from the alternator and turns on, no trigger wire.
Nice to have that capability built-in. I don't understand why all dc to dc charger manufacturers don't include the equivalent of a Battery Isolator (BI) or Automatic Charging Relay (ACR) with their units. It's a basic requirement for operating a dc to dc charger in the vast majority of installations.
The 50a Redarc dc to dc charger is a nice unit, built like a tank. See a number of off-roaders using them.
One big caveat though, they cost $500+. One could potentially purchase & stack 4, 40a Renogy dc to dc chargers for 160a of output for $519. Of course, this would require a dedicated, high capacity alternator to provide the necessary current. I've been told Renogy doesn't recommend stacking (connecting in parallel), but I've stacked 2 of them with no issues.
Would be nice? If it only costs 20% of one that does and performs the same function, seems like nothings wrong with the picture.
