Exactly what I've been wanting on the boat too. Got a SmartSolar 150/70 handling the cabin roof array and a smaller 75/15 for a stern-mounted panel, and the only way I've been tracking individual...
@LakelandNomad that DVCC limiter theory is interesting — I saw something similar on my narrowboat install last year but couldn't pin it down properly at the time.
One thing nobody's mentioned yet:...
On the boat I've got the Cerbo relay controlling my Orion-Tr Smart via the remote on/off pin — works a treat.
@GarySmith58 good shout on coefficients. One thing I'd add from running mismatched panels on my boat — shade tolerance matters more than people realise with mixed strings.

Not a motorhome but the principle's identical on the boat — three days of solid grey and you find out fast what your "emergency" setup actually is versus what you...
Been down this exact road on my own boat. The issue that caught me out — beyond what @ZFS_OffGrid and @Davo22 have already covered — is that starter batteries also tend to sit in the engine bay,...
@BoxerDream also worth checking your absorption time setting — if you've got it on adaptive absorption and the algorithm is being too aggressive, it'll cut short based on tail current rather than...
@Kate1970 January on a boat is brutal for solar, I'll tell you that much. Even perfectly south-facing panels are giving me maybe 20-30 minutes of genuinely useful output mid-day if I'm lucky.
@BoxerProject that analogy is actually spot on 😄
Worth adding — are you monitoring voltage at the battery terminals rather than at the charger output?
@GafferTapeKing19 is right about the relay, but worth noting the contacts are rated pretty low — 4A max if I remember correctly.
Been there with mine on the boat. Worth checking if you've got the temperature sensor actually making proper contact with the battery itself—mine was just loosely taped on and drifting away from...
Had the same worries when I first mounted mine on the boat. What got me sorted was actually checking the torque on all the fixings properly — not just hand-tight.
The DCC50S is genuinely solid kit — I've got one sat on the shelf in the boat actually, pulled it when I switched to Victron too.
