I am in a deadlock situation. I was hoping the nice community here could help me choose?
I need to do something about the charging
Currently refitting a 37 feet sailboat. Going for ARC
2003 B with original 50 A alternator
. 300 Ah housebank. Will add 400-500 W solar panels
and possibly a wind generator
Proposed config # 1:
An expert from the cruising community, well-known and reputable, recommends exchanging the original alternator for a Balmar
, Mastervolt, Eletromaxx etc + external regulator
and + temperature sensor.
Mastervolt - Innovative power systems<br>for autonomous use
While doing so, upgrade to at least 100 A charging current
. Must reprogram the alternator or regulator (haven't figured out which, perhaps both), which, the expert states: requires high skills!
Most mechanics in Marina Workshops look puzzled and "never heard of the idea" (so how find somebody to do the reprogramming?). Not many other long distance cruisers recommend this, at least not ones I've been in contact with.
Proposed config # 2:
Keep current alternator. Purchase
the Sterling up to 130 A:
Alternator to Battery Chargers up to 130A | Sterling Power Products
Recommended by long distance cruisers and forums
. More often recommended than config # 1.
Or should I write "budget and time constraints".
Not much up to the task of programming stuff, don't really know how to. Not much up to the task of modifying engine
mounts for a Balmar
, Mastervolt etc alternator. Unless absolutely necessary.
Ambition level says go for Sterling. But if config # 1 is way much better than # 2 I just might go for that. Also, I am not that interested in electrical
systems. Want to do things right but at the bare minimum. Everything electrical
should work 100% automatically.
People in forums
mention building their own charging systems including shunts at the battery
side to measure current etc. Great, but don't have time or interest
Which config (#1 or #2) is more KISS by the way?
I can imagine a config # 2 B by the way. There exists upgrades to the original alternator, 70 A and 100 A. Same mounts!
Would I be better off with one of those + Sterling? Or is the idea of Sterling that the original alternator will do? But shouldn't I get faster recharge of drained batteries with more current, eventhough there is a Sterling unit?
