Hi Josh,

You have probably posted this already but, what make and model of solar
panels do you have there?  Do you find shading by the boom has a noticeable
affect on the output?

Re: Stus-List Portable generator question

[Josh Muckley via CnC-List]

 Bruce,

The PO put two 4D batteries in the compartment under the stbd settee just
forward of the sink.  They were shot when I purchased the boat and I needed
something to get me 350 miles home.  Not being familiar with the local
chandleries I found myself in the nearest AutoZone.  3 of the largest amp
hour "marine" batteries fit pretty well and got me about 345Ah.  They
survived ~5 years and cost ~$300.  I just replaced them last year with four
Trojan T105-RE.  They are 6v and 225Ah each so 450Ah total.  I had to
rebuild the compartment a little and lined it with epoxy and fiberglass.  I
had to get creative about the mounting and anchoring and then had to
shoehorn them in.  As with most boat projects it was a bit of a
compromise.  The terminals where only available in a high format so in
order to accommodate I had to add a piece of 1x1 trim under the entire
bench.

Too high of a charge capacity exacerbates the boiling of the cells.
Typically the only opportunity to see the full current of any charger is
when the battery bank is below ~80%.  As the charger is charging the
battery it is pushing the voltage higher and higher to attain max charger
current.  Once it reaches 14.7v the charger has completed bulk charge and
the battery is roughly at 80%.  The completion of the charge is called
absorption and the charger will hold the voltage steady at 14.7v by
reducing the current.  Once ~2amps of current is reached the battery is
said to be full charged and the charger will switch to float mode where it
holds voltage at ~13.4v and ~2amps.

So let's say you where at 50% and had a 100 Ah flooded lead acid battery
and a 50 amp charger.  The charger will ramp to max current (50amps) and
max voltage (14.7v) until ~80% but the lead acid battery is literally
incapable of absorbing the power fast enough so excessive heat is generated
and while not quite an equalizing voltage boiling will occur.  I don't
exactly understand the method of destruction but heat is the enemy of lead
acid batteries so any time they overheat you are probably damaging them.
The boiling is helpful for mixing the electrolyte but will also mean more
water is needed more regularly.

So yeah, short answer, too high of a charge current will shorten battery
life.

I have two 100 watt flexible panels that typically put out 5 to 6 amps each
for a total of 10 to 12 amps.  My 450 Ah bank could accept 115amps(ish) so,
 10 times as much solar for a total of 2000 watts!  I don't have enough
real estate to mount that many panels.  But the point is, you probably
won't exceed the limits of the batteries.

 Sizing for your system would probably be limited by your budget and by
your available space.  I would maximize the use of space and stretch the
budget as needed.  A Nova-Cool rep told me that a 100watt panel was
typically enough to keep up with a properly insulated refrigerator.

To minimize potential damage as result of deep deep discharge I have a
priority start on my 450Ah bank.  In the event of a solar failure, and no
shore power, the battery will be disconnected at a low voltage setpoint -
conveniently enough that voltage setpoint is 11.7v.

Hi Josh,
Just curious, what batteries do you have in your bank, and where are they 
mounted?  

Am I right to presume that having more charge capacity would result in shorter 
battery life?
Just trying to size my eventual solar panel purchase.

Much of your problem is a matter of battery capacity as much as a matter of 
charging capacity.  I have ~450 Ah of capacity on one bank, a 90 Amp alternator 
that never reaches full load, and 200 watts of solar.  Even without the solar I 
was able to comfortably keep the the fridge running and the lights on when 
cruising for ~2 weeks.  The half hour to hour of engine operation to anchor or 
moore in the evening and the same in the morning was always enough to keep the 
batteries charged.  
Keep in mind that the battery capacity should be at least 4x of the charge 
capacity for flooded lead acid and at least 2x for AGM.  So a 400 Ah or 200 Ah 
respectively for a 100 amp alternator.

In my experience, if you ALWAYS put fuel conditioner in the gas you put in
the generator you won't have gumming problems. I never seem to know wen
i'll use a small engine next so I always use fuel conditioner.

I keep the Honda 2000 generator in my Sail locker with the gas cap vent closed 
for use as a back up charger and to power the single cup Keurig when we’re on 
the hook.  Much quieter than firing up the diesel.  If I need to run it, it 
goes forward to the bow and as mentioned, can barely be heard in the cockpit.  
The vibration on the deck is actually louder than the exhaust.  Off season, it 
comes home for home emergency use. Bought mine as a factory Re-manufactured 
unit from Home Depot for as cheap as the wannabe Chinese knock offs.

Damian,

The Hondas and Yamahas seemed to be highly regarded.  When I race/cruise
offshore with the fridge, autopilot, plotter etc we run the engine about an
hour a day to charge the house bank with a 60 amp alternator.  Unless you
are already carrying gas for a dinghy you might want to reconsider a
generator.

My 2 cents

That would be incredibly dangerous to say the least! Those gensets should NEVER 
be below for ANY reason! They obviously contain gasoline and were never 
designed to be stored in a relatively sealed compartment with people, 
electrical gear, and open flames.
For actually trying to run an air-cooled non marine gasoline engine inside of a 
boat - all that times 10,000. This sounds like a very good way to kill yourself.
I saw something like this when I worked on boats and flat out refused to ever 
step on the boat again unless our very first job was removing the entire setup. 
No way was my name going to be on that boat even if all I did was change a 
lightbulb!

I have been thinking in similar lines of the Honda 2000i or so. 
What I have been playing with is a design for my C&C 35 MkI where the generator 
would sit below the Starboard cockpit hatch just behind where others have put a 
refrigeration system for the ice box.
1. Running the necessary cables for plug in to power 
the batteries
2. Setup an overboard on the transom for the exhaust 
with potential additional silencing
3. install light weight sound silencing material on the 
underside of the cockpit and main cabin bulkhead.
Since I still have my atomic four I am also considering putting in 
a fuel pump off the main gas tank.

When I get this done I will send picks and diagrams.

Also Damian hope you are enjoying it up there, I grew up on the 
north east side of the Island.

I use a Honda 2000i companion (has 30 amp plug) as a backup power source. At 
least until I get my solar up and running. The Honda is quiet and wind disturb 
neighbors in anchorage. I would
Put the honda on the bow and not hear it in the cockpit. The 2000 will also 
power a hot water heater, or 1500 watt space heater.

Subject: Stus-List Portable generator question

A question for your collective wisdom:

I am scoping out upgrading my stock 55A alternator to a 100A Balmar, and 
related upgrades to the controls. I had a very productive discussion with Rod 
Collins at Compass Marine (mainesail), and we worked out the details. 
Unfortunately he's booked out through the spring, so this job will wait until 
next winter.

So thinking then about keeping the batteries charged, and the fridge running on 
our long summer cruise - where we may go for weeks without access to shore 
power, I got wondering about using a portable generator to charge the batteries 
- as an alternative to many hours of running the diesel. There are a couple of 
Hondas that might do the trick 2000 Watt, weighing 47#, 1000 Watt weighing 29#.

Have any of you tried this? What could (would) go wrong if I plugged this 
generator into my inverter, to charge the batteries?

Regards,

Damian

Much of your problem is a matter of battery capacity as much as a matter of
charging capacity.  I have ~450 Ah of capacity on one bank, a 90 Amp
alternator that never reaches full load, and 200 watts of solar.  Even
without the solar I was able to comfortably keep the the fridge running and
the lights on when cruising for ~2 weeks.  The half hour to hour of engine
operation to anchor or moore in the evening and the same in the morning was
always enough to keep the batteries charged.

Keep in mind that the battery capacity should be at least 4x of the charge
capacity for flooded lead acid and at least 2x for AGM.  So a 400 Ah or 200
Ah respectively for a 100 amp alternator.

Re: Stus-List Portable generator question

[Ken Heaton via CnC-List]

I occasionally use a Honda 2000i, on longer cruises, but try not to use it
in an anchorage in the evening or after dark if there are any other boats
there as, while it is very quite, it isn't silent and most of our
anchorages are.  When in use I usually put the Honda in the inflatable and
let the inflatable drift a couple of feet away from the mother ship.  Can't
hear anything at all from below then.  The inflatable has an aluminium
floor.

When not in use we store the Honda in the cockpit, under the helmsman's
seat, or in the shower if it is going to be nasty out.
