Redarc 40 amp DC to DC Charger issue
After about 15 seconds or so when I start the engine my shunt reads up to almost 49 amps and then the 60 amp input breaker pops. Whats going on here? Isn't the charger supposed to limit the output cur...

Not sure if all Redarc dc to dc chargers operate the same. It appears some Redarcs may set an output/charge current ceiling (and vary input current), whereas other models may set an input current ceiling (and vary output/charge current).
Our 40a Renogy dc to dc charger can vary the output/charge current from 0 to 40a. After 9 months of heavy use, under all conditions, I've never seen the output/charge current increase beyond 40a---it's a hard ceiling. Although the *input* current on our Renogy always stays below 45a, some installations (with longer cable runs & smaller gauge cables) can force the input current to rise as high as 60a to compensate for various voltage drops between the alternator and Renogy input.
