Recently I replaced our battery bank of 3 X 110 A/hr 12 V fla, with 4 X 6 V 225 A/hr, deep cycle fla golf, wired to give 12 V 450 A/hr. I also fitted a Victron Bluetooth shunt, and 2 X 100 Watt solar panels charging the house bank through a Victron MPPT unit.
With the shunt, I can now see that the Adverc cycles between about 14.5 and 13.7 Volts, and continues even long after the battery is 100%.
Is there a danger that this will eventually overcharge the batteries? The previous bank lasted eight years with the Adverc, but thought I would ask opinion of more knowledgeable forumites.
Also, the battery charger is an older Morven 3 stage 30 Amp unit of 2003 vintage - is there any advantage in fitting a Victron programmable 30 amp charger, or any other suggestions?
My usage profile is live aboard from April to September around Ireland and UK, and abroad for the other months with everything off and battery trickle charged by Morvern unit at 13.7 Volts.
