Hello Ben,
Are you replacing your Dolphin 50 Amp because it also failed? Or just because you want to upgrade.
If it is still working, I might be interested.
My Dolphin 50 amp failed 2 years ago, I replaced it with a 60 amp MDP (which had purchased Dolphin).
Then I thought my 30 amp was failing, but did not, and I replaced it with a MDP 40 amp.
I thought I could have them both work together (like the Dolphin 30 and 50 could) but apparently not… I contacted the company but have not heard back…
In my case I did not replace the AC nor DC wires, but I stayed on the safe side and picked 40 and 60 Amp.

Subject: [Amel Yacht Owners] DC cable sizing for larger charger

I recently replaced my failed Dolhin
30 Amp charger with a Mastervolt 60 Amp charger. I did not
upgrade either th AC or DC wiring. All seems to work well.
Now I'm considering replacing the 50 Amp charger with
a Mastervolt 80 or 100 Amp unit. I think AC input wire
size is OK. Amel used the same size wire for both 30 and
50 Amp units. My concern is DC wire size. Not sure
but it appears to be 25mm sq. (3 AWG). Again Amel used
same size for both 30 and 50 Amp chargers. My question is
will this size wire support larger charger? Or will I need
upgrade to 35 or 50mm sq.? Has anyone done this upgrade
without wiring upgrade?
