100 amp charger on sm2k
|
Thomas Kleman
My original 100 amp Dolphin died about 4 years ago, and it made me nervous anyway because it lacked a battery temperature sensor. I replaced it with a 100 amp Mastervolt charger, which seems to have died this weekend....having verified all connections and voltage and still getting nothing. Wondering what others have chosen when replacing the Dolphin. Having done several hours of customer complaint sleuthing it seems that the Mastervolt can be temperature sensitive and the battery chargers on a SM are relatively close to the gen.

Hi Thomas. If the dolphin is still available I would go with them. I replaced mine 5 or 6 years ago and found the company very good and the chargers work well. Danny SM 299 Ocean Pearl

Danny, I have seen more Mastervolt chargers fail on 54s in about 5-10 years of life that I have seen Dolphin chargers in 20 years of life on SMs. And remember there are more than twice as many SMs. I don't have any specific data, but I believe that Victron may currently offer the best charger. I was told that Dolphin ownership changed about 2006...I am not sure about this. Best, CW Bill Rouse 720 Winnie St Galveston Island, TX 77550 +1(832) 380-4970

Tom,
Victron Energy, in my opinion, makes the best chargers.

Any one using the victron skylla 100/24 ? I'm persuaded that I should probably buy a 100 amp charger for my generator-driven battery charging but realize that earlier SMs used an 80 amp charger.........once again, it comes down to leaving the boat as it was designed, I guess.

We have had a Victron Skylla 100/24 on Elyse since the old Dolphins died 5 years ago. Very good experience, no problems at all. Very flexible and versatile charger, mode selectable for all types of batteries. We have 660Ah of 6V AGM batteries in 3 banks of 4 with balancers, works very well.

I have had the Skylla 80/24 for 3 years now for my 520AHr bank of deep cycle lead-acid batteries. So far no problems whatsoever.

Kent, why did you choose the 80/24 vs. the 100/24? Ian & Margaret S/V Loca Lola II SM153 Exumas, Bahamas

When I purchased Amelia in 2017 both Dolphins were dead. I replaced the 100 amp with a Xantrex inverter charger(Special offer at Budget marine Grenada)8 and a 30A Mastervolt, which still works fine but judging from this forum I shoulda gone Victron. It is easy to be wise. Still I am happy with solar, wind, 175A Alternator, Xantrex, Mastervolt. Between that lot we gonna be well charged whatever.....on my last quick passsage north from La Palma, my battery bank stayed at 100% for the entire passage despite running deep freeze and two fridges, radar and autopilot 24/7. Mind you the apparent wind was drumming permanent 20-35kn. The wind generators were cranking. Enjoying peace and tranquility of Funchal....

I had an 80A charger from the time I bought Kristy and it was plenty. I’ve added Solar since then and rarely run the charger for more than 45min per day. Still thinking about a wind generator at the top of the mizzen, but haven’t pulled the trigger on that yet.

Kent,
I have to agree with Bill. We have a wind generator, it came with the boat when we purchased it and then broke. We replaced it with a clone but probably should have saved the money for something else that hasn’t broken yet.
If the wind is blowing 20-25 knots consistently it is worth it. But how often does this happen? At this wind speed it will put out about 5 amps per hour and help during the night when solar panels are sleeping. It is just enough that I do not have to run the genset in the morning to top off the batteries until the solar kicks in (we are running all three ref/frz).
You can do the math for the number of days you spend per year cruising, the number of days you will have ample wind and compare to the cost and wear on the genset running we you need the extra omph. My guess is you will find it is not feasible.
Right now we have winds of 5-10 knots and it is the same for the rest of this week. We are on the hook and the wind generator is totally useless.
If I had to do things over, I would add more solar and increase the size of the battery bank
With best regards,
Mark

.......am sure your right Bill unless you live in the roaring 40’s and do most of your sailing in higher latitudes!!

The Rutland wind mill having sailed from the Med to NZ lost its feathers in gusts of 45 to 55 knots off Kaikoura on the west coast of the South Island. It was replaced with a silent wind generator which, while expensive, has been excellent at maintaining power levels in the batteries and has a built in breaking system John Hayes NGA Waka sn41 Wellington

Greetings all,
I have a top-of-mizzen Rutland 1200, installed 2018, cost to purchase-and-install ~$2,200-. The running count for the wind-gen since it was last reset 920 hours ago Arriving on-anchor, La Playita, Panama), is 547Ah contributed to battery charge; =~ 0.6Ah per hour, =~ 15W average per.hour contribution. Since last reset, we have been in a typical steady wind, but not-so-windy location. Previously, when in windy locations (meaning, wind in general blowing always 18 knots, but often 20-30), we were seeing easily double, sometimes triple this, on-average.
These overall production figures are somewhat BELOW what would otherwise be seen in a stand-alone wind-gen set-up (without solar), because at mid-day +/-2.5H when your solar cells pumping it in, or when the batteries are sensed as fully charged, the wind-gen switches off.
Also, when you are on genset (or motoring), sometimes the wind-gen senses this and shuts down also.
But when the wind-turbine is spinning, the output is within 5% of the manufacturers curve (case: windy at night, no solar in competition, for example).
Overall, with the solar and wind-gen, my need to run the genset whilst on anchor is reduced to about 50% of what is was before (no solar or wind). On longer offshore passages, we have only a few days here and there, so not really able to say. So I am still planning fuel burn for offshore work on the pre-wind/solar basis of 2 x 1.5 hour genset runs per day. I am happy with ‘free’ power from the shaft gen – enough to cover the NAV Station – when STW >7 knots. I switch the shaft-gen off if I really need to squeeze for speed, as I estimate that the shaft-gen pulls the STW down by between 0.5 and 1.0 knot. For really long-distance work (say, >3,000nm), that 1knot pull-down relates to an extra 2 days passage-time. There is always a trade-off.
I am glad to have the redundancy provided by solar and wind in combination, although this is only partial at best.
We are not at this time considering a second wind-gen. We are thinking to increase the solar to 800-1,200 watts. The panels themselves will pay for themselves over time, but the capital expense of the arch is harder to reconcile.
Cheers,
David SM#396, Perigee Pacific-bound

I have had very good experiences with my Superwind half way up the mizzen mast. It substantially contributes to balancing the power needs on Kincsem on most days without anyone noticing it is there. My 400 W solar usually contributes more here in the Med, and when offshore, my Watt & Sea blows them both away, but in my view it’s all about alternative sources. Wind is great at anchor particularly in the Aegean and sailing on all courses other than a broad reach or downwind.

“and has a built in breaking system”I seem to have a few of those profucts on my boat too, lol 😜 (Sorry just couldn’t help myself John!) cheers Dean
