A few questions for you befor we give you something to think about. What kind of regulator
are you thinking of getting? I researched the Balmar
regulators and the appear to be very well functioned. They also allow you to connect multiple alternators to a single battery
What do you plan to do for your starting batteries
? How will they be charged? What kind of battery
configuration and size do you have? How many AMP hours? Are they 6 volt? 12 volt? My boat
only has one starting battery and that is connected to both starters. I have the new Yanmar 3YM30
engines. They are configured such that you only connect one cable for both starting voltage and charge output. Therefore my engines only normally charge the starting battery. I have added a battery combiner/diode to charge the house bank, after the starting battery is charged. How do you plan on configuring them?
Originally, I thought to get upgraded alternators (100 amp Balmars). But, I thought of the optimal charging configuration and concluded that expensive marine
diesels did no present the optimal solutions. Since you are concidering a multiphase regulator
, you are familiar with Bulk, Acceptance and float charging levels. My issue was with the float charge. To optimize this phase you are putting in relatively low amount of current
(2 amps or so) at relatively low voltage (13.2 or so), this is a very light load for a 20 hp and above diesel engine
. Higher loads are significantly better for their overall longevity. This lead me to concluded that I'd be better off using some type of alternate charging source. I have just ordered an Air X marine wind generator
and I intended to mount several solar panels
on my boat. This will allows me to have a prolonged float charging phase as well as limit my overall discharge level. Both of these are good things for any type of battery bank.
In anycase let us know, I am certain we can give you some good things to consider as you configure your system.
