Electrical systems have always perplexed me, so if someone can lend a thought it would be apprecitated.
I have a two bank battery system on my 30 foot sailboat. The existing battery charger is the old style charger that goes at one speed all the time and appears to be dieing.
I want to upgrade to a smart 3-stage charger which will take care of my two bank set up, but am confused on the different available chargers.
There seems to be numerous variations of the two bank chargers available ranging from 12 to 15 to 30 amps. My confusion comes from where this amperage is measured. Is this the input amperage (ie. the amperage coming from the panel to the charger?) or is it the exit amperage (ie. going from the charger to the battery)?
My shore power comes in to the A/C panel at a 30amp breaker. I have a dedicated circuit at 15amps for the charger.
I''m guessing that the advertised amperage on the charger is going from the panel to the charger, but want to make sure.
Also, if you have a preference on manufacturer or model feel free to share.
