So, I have looked through the Victron Community and have not found my particular situation.
I have 2 x Victron AGM's 230Ah, in Parallel. BUT, each is on opposite sides of the small yacht, 1.5m apart. The Starboard battery is the home of the DMV shunt.
I also have each Solar panel driving one MPPT 75/15 and each separately, and directly, connected to port and starboard batteries.
Now this has worked fine, but now I notice that there is a slight discrepancy with the battery voltages (obviously because of the 1.5m connection 25m2 wire) but why? each battery is being charged 'separately' even though connected together.
Also, the MPPT's don't give the same 30 day yield (202KWh starboard and 230KWh port)
that is close and after all they are two different panels, shaded maybe differently.
This got me thinking about the shunt being only on one side only, capacity might be wrong.
we are in South Africa and it is very sunny, so no worries, the battery bank is pretty full all the time, but what happens when we sail in days of clouds?
I want to know if my setup is good. redundancy and all, but I I doing any harm?
As I finish this post I see batteries at both 12.90V
thanks for help
Alex
