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!

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.

Display VDS 215 MDS - nav table A54

Dear Amelians,

did any of you have to replace the display on the navigation table?  
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.
The diagonal of the opening is approx. 45cm / 17,5 inch.

Thx a lot for your hints.

Best regards

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,

Arno

Re: Holding tank riser

Darren an Karen,
We cut the sump (funnel part) of the tank outlet off. Then we extracted the hose, inserted and glassed in the FRP riser, through the inlet hole and glassed back in the the funnel part of the tank outlet.

Tom and Kristin,
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.

I have a switch in the cabinet where the steering rack is located

I don’t know if it was original. I left the switch in place, but disconnected the relay that did the remote connection. I would just connect with jump leads if needed.

Maybe there is something like this in your setup that has failed?

Mark,
Can you reproduce the fault by attempting to start the engine while the house bank is turned off?
As Thomas mentioned, maybe you have a PO mod where something in the start/run circuits for the engine depend upon the 24V house circuit being online.

Hello Bill, hello Arno,

we are just leaving La Rochelle, I will respond tonight.

Nicolas took measures and pics of the first manifold too. He should be able to create a design of this too.

Re: 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.

I would venture to think the idea was to be able to have intermediate positions. Not that we have made use of it much, but maybe one day...

One handed operation sounds great, though

Hi Arno,
I know what you mean!   Anyone who needs to enter my boat without me present is always amused by the plethora of instructions I give them about entering.  Contractors look at you askance .. "do you think I don't know how to enter a boat?" lol

Personally, the only thing I don't like about the Amel system is that the door can free-fall all the way.  It would have been great to have some kind of piston in the design which supported the weight of the door, and either lowered it in a controlled way, or required a little downward pressure to open. As if our boats are not complex enough, right!

I think most people looking at your mechanism for the first time would find it obvious to operate, and probably not let the door drop.

Re: House Bank vs. Engine Start

Thomas Kleman
 

The house bank and start battery should be completely separate. But you've had not 1 but 2 coincidences. On your boat, the state of the house bank seems to influence the start circuit. Before I did anything (like take the boat somewhere), I would label and test the entire start circuit. Maybe a previous owner made a "modification". 

It could also be 2 problems; you may have a problem in the ignition/starter circuit, the start stop solenoid, or something else. 

Sounds like a long weekend with a multimeter.
Good luck.

The start battery was a bit over 12 Volt, I didn’t check it at the starter. Once I replaced the house bank everything worked fine, which I fine odd.

House Bank vs. Engine Start

Mark Garver
 

Okay, so recently I had a main bank failure, but what is disturbing is that the engine wouldn’t start. Confusing as I have a dedicated engine start battery, same for the generator. Has anyone experienced this, or have any idea why? Is there a way around this? I can’t imagine this happening in an anchorage, or at sea.

Thanks,
