When building my boat we increased the size of the battery bank significantly from the base spec (from 324 Ah to 1,000 Ah) and also upgraded to Victron Super Cycle AGM. The charger was upgraded from a 12/30 to a 12/60. The thinking was that shore power is generally limited in amps but usually there is plenty of time. However it seems that we're having trouble getting the bank fully charged on shore power. Now reviewing the Victron spec sheet I see that not reaching full charge may be caused by undersizing the charger presumably because the second stage is on a 4 hour timer. Any thoughts on this? Should I replace the Centaur 12/60 with a 12/100? If so will shore power typically be adequate to power the charger?
