Re: solar panel

 

This may not be the case in any of the situations above where more energy is noted than rated values, but:

If when installing the solar panels if you connect the negative wire from the MPPT to the shunt or near the shunt, you will see erroneous energy reported. 

As you see below, this may be more of an issue with some SM owners who find an easy place to connect the negative input wire.

Great - Thanks Denise, and Barry .
And Mark for the install tips. 
I´m about to order the OceanChef and want start preparing with blocks.
Do we know if there is a difference between the distance from sidewall to sidewall in a SuperMaramu and a A54.

And again thanks all of you for this fantastic forum with all the knowledge gathered. Hope i can contribute, perhaps with some info re this install.

Re: Holding tank riser

Mike Ondra
 

Hi Darren,

The fix you referenced we did a year ago and have had no problem since. What I like with this solution is the continuous sanitary hose all the way from the toilet to the top of the holding tank, no joints to leak.  Reaming out the deteriorated copper and fiberglass to allow for the insertion of the tube I found quite difficult until acquiring the proper tool. See the posting on 7/31/20 https://amelyachtowners.groups.io/g/main/message/53493?p=,,,20,0,0,0::Created,,aletes,20,2,40,75913168 for more details. One must also be meticulous about getting the resin completely around the pipe penetration from above so that it is fully sealed.  We did abandon the old riser inside the holding tank as we could not figure out a way to remove it without cutting an access port into the tank.

Subject: Re: [AmelYachtOwners] Holding tank riser

 

Hi Tom and others on this forum,

 

Kaz and I are newby owners of our Super Maramu #171 and this is our first post to this amazing forum

 

I found a similar issue with our holding tanks this morning, it looks like there was a solid pipe through the bottom of the tank which then had a 35-40mm flexible pipe connected to it on the inside of the tank which went up to the top of the tanks and then curved over to point back down.

 

In both tanks the pipes have broken off on the inside of the tank, I'm thinking of replacing the pipe going through the bottom of the tank with a solid bronze pipe going up to near the top of the tank as in the modification suggested in this PDF

 

I like the idea of going into the side of the tank at the side as well, but do find going in the bottom neater.

 

I'd like to get the old flexible pipe out of the tanks as well, not sure if this is possible without cutting an inspection hole in the tank.

 

I'd be interested to hear about how you go about your modification.

 

Kind Regards

My aft head holding tank riser has separated from the lower part of the copper fitting. So inflow to the holding tank enters at the bottom of the tank. Despite this, there is no leaking from the fitting.

I've read the various posts on fixes; replacing the fitting, mounting a smaller diameter pipe inside what remains of the original, etc.

One goal of the project would be to make it easier to maintain. If the idea is to have the black water enter at the top of the tank, I'm wondering if anyone has moved the inlet from the bottom of the tank to the upper side. This would have the benefit of allowing the hose to run outside of the tank and turn left, dramatically simplifying clearing clogs.

Anyway, I want to consider all possibilities before I open this can of worms.

Re: solar panel

Sv Garulfo
 


I usually find that a slight overcast yields better output, but i don’t know if it’s related to the potentially lower temperature of the panels or the dispersion of the solar rays.

My skin also agrees; an slight overcast is an easy way to get sunburnt. 

I also think some manufacturers promote better guaranteed output over the life of the product, even if it means having to put forward a lower power rating to start with. So your panels may start with a better output than promised and end within the advertised  range. 

Scott,
With 900W of solar, occurrences of 35+ amps are pretty rare for me. It needs an almost vertical sun. I don’t think you’re missing out much.

Best,

Best days I’ve had around 5.8-6.2 KWh  from the four panels, and these were sailing days back in early April, not on anchor. Now, on a good day here in Carriacou I get around 4-4.75kwh and last week , as low as 1.5kwh across the four. The weather was pretty special in Southern parts of Grenada last week. 

Both sets are wired in parallel. I recently switched the Bimini ones from being in series (as per instructed ) to parallel but  haven’t a really seen a  material difference in performance. It’s hard to make any meaningful comparison/ analysis on the switch over mainly I think due to changes in the weather here in Grenada over the past few weeks. This week the weather in Carriacou has been pretty good but hazy (Sahara sand apparently) but the Bimini panels now in parallel have performed worse than when in series. Will continue to monitor, too many variables to make any meaningful conclusions right now. 

I have to run the genset roughly once a week at anchor, mainly for the water maker. My 3KW Quattro overheats after about 30mins if I am running the water maker off the Quattro/ battery bank alone. As the season changes further, the genset hours will obviously increase, until I move on after AZ2 jab scheduled for mid June. 

Bill , if you come up with a plan for the insulation please share. Like you the fridges and freezers are a significant portion of the overall daily consumption, even when taking into account that I cook / bake on electric.

Most of the 6kW-hr power usage is refrigeration.  We run two freezers, and a fridge, and the Amel installed insulation is not the greatest. A serious upgrade of the insulation is on our wish list.

Re: solar panel

Scott SV Tengah
 

Just curious for those of you getting more than rated output, how long does that over-rated output persist?

I have 960W of rear arch mounted LG Neon2 panels and I've seen it spike to slightly above that, but my Victron MPPT is limited to 35 amps output so charging output is usually cut off by the MPPT output limitation.

Most of the time I am sitting around 860-920 watts max output at solar noon. I believe my spikes above rated output occur around solar noon on partly cloudy days when the sun has been behind a cloud, the solar panels cool down and then get hit by strong solar insolation. At that moment, I get the output spike, but once the panels heat up again, the output drops.

Remember, solar output is highly dependent on panel temperature. That's why deck/bimini mounted panels perform so much worse than arch mounted ones. Well that and the shading issue.

If I'm wrong, the power output curve should remain above rated output for an extended period of time. If I'm losing out on amp-hours because of my "undersized" MPPT, I want to know!

Re: Display VDS 215 MDS - nav table A54

Hi,

If your problem is that the actual LCD panel is failing (as it was for me) then you can replace the actual LCD panel itself fairly easy. If you want I can try to find the supplier I found to order a brand new identical LCD panel. From the same supplier I ordered a touchscreen panel that replaces the glass panel in front of the LCD. That can be used in conjunction with the NAVNET 3D system however meanwhile I’ve upgraded that system to the TZ2 blackbox system from Furuno.

Re: House Bank vs. Engine Start

 

Mark,

SM 105 was repowered with a different main engine. I am not sure who did it, but this is probably one source of your problems. I believe that some serious wiring changes were made including the termination of Amel Bonding wires (yellow/green). Additionally, I assume that the new engine was NOT installed isolated and that there is also a crossover of 12 & 24 DC negative at the engine.

A review of your wiring needs to be done.

The manufacturer doesn't seem to produce this anymore.  
Are there alternative displays or other sources of supply for this?

It needs 2 VGA connections.

Re: Amel 54, For those who do not really like the entrance hatch locking system

Arno Luijten
 

Hi Thomas,

I did consider the intermediate position case. Apart from the fact I’m still able to add it if required the reality is that I never used it in the time we’ve owned the boat. When rain comes in from behind I typically close the hatch all the way up. When the sailing is so bad I get to the point of closing the hatch because of potential waves I will close it completely anyway.
The new lock also makes closing and opening the hatch much faster and a one hand operation.

Cheers,

Our solution was to fiberglass in a 1-1/2”OD x 1-1/4” ID FRP tube riser through the inlet hole. The tube went almost to the top of the tank inside. Works well.
