I did a DC refit this past spring which included new battery trays, 3 banks of wet batteries (house, start, genset), home run SMX DVM’s from Seaboard Marine to each battery bank an ACR between the start and house with custom panel at the helm to monitor, new On/OFF battery switches for the House & Genset banks, an On/Off /Combine switch for the Start, added a ProMariner 12-60P 60 amp charger dedicated to the house with a remote display and kept my old 40 amp Pro-Nautic for the start and genset battery charger.
Previously the original 3 bank Pro-Nautic charger was set-up to charge all three banks and it would kick back to minimal output when it sensed the Start and Genset banks were fully charged making it difficult to impossible to fully charge the house bank when running the generator on the hook. It just made sense to add a separate dedicated House charger and have the Start and Genset banks on the original charger.
For the first time in 4 years since owning this boat battery management is A+ and without issue! Not once did I need to run the Start/Genset charger as the engine and genset alternators would always bring those banks to 12.7 / 12.8 volts. The ProMariner 12-60 would then be able to do its job quickly and shut itself down to conditioning mode or “0” amp output on the genset or shore power when the house was fully charged.
I couldn’t be more pleased with this refit and battery management with the Seaboard Marine DVM’s that always let me know exactly where I stand!
Thank you to Rob Schepis for your article on the SMX DVM’s and once again leading me down the right path.
