Re: VICTRON MPPT 75/15
Gregory Shea
Bonjour Alain,

I have your problem because a cheap Chinese panel in my solar array cannot reach minimum voltage for the MPPT to turn on each morning. The MPPT “sees” the minimum voltage in a parallel system so, if one panel is under performing, the MPPT won’t turn on,
even if all the other panels are above minimum. You can troubleshoot it by checking the voltage output of each of the panels connected to that MPPT, after you know you have enough solar power in the morning because the second MOPT switches on.
I don’t remember what the minimum voltage needs to be, but your Victron App should tell you.
I solved the problem by putting an inline switch in the positive lead from the weak panel. When the MPPT does not start, I take take panel out of the array by using the inline switch. When the MPPT starts, I switch the weak panel back in again. Once the
controller is functioning, it will accept the weak panel as just one part of the array and everything functions normally.
For me, or was not a serious enough problem to justify buying a new panel, but that would be the correct solution.
That is one possibility, hope it helps.

Re: 24V+ Isolated Ground Leak
Paul, I helped you find a potential problem with the two unknown wires connected to the negative side of the 24v PERMANENT BUS. Did you trace those?

Re: 24V+ Isolated Ground Leak
Hi Martin,
Many Amel boats have been modified (ours included) and perhaps this binding wire was for a piece of equipment that had a metallic connection to saltwater, but that piece of equipment is no longer there. For example we replaced the Calpeda Air con pump with a March pump. The Calpeda pump is all metal and has a bonding wire connected usually to the metal one way valve on the outlet. The March pump has no metal parts in contact with salt water hence no need for a bonding wire...so it is no longer connected. Rather than a list of components, as I said many Amels have been modified, you should check and be sure that EVERY metallic part that is in contact with sea water has a bonding wire attached to it...and that bonding wire is connected to the rudder zincs.

Re: 24V+ Isolated Ground Leak
Hi Paul,
I think things have gone a little awry in this discussion. The positive and negative sides of your battery bank should float i.e.NOT be connected anywhere to the bonding system (the green/yellow wires to the zincs, sometimes erroneously called "ground") So, with your multimeter on VDC you should measure close to no volts (no potential) between +ve to the bonding wire, and -ve to the bonding wire. The fact that you read +25 VDC between the +ve and the bonding wire tells you that, somewhere, the -ve from your battery bank is connected to the bonding. This is what the MASSE lights tell you....either +ve is connected to the bonding or -ve is connected to the bonding, somehow. The fact that when you flip the navigation breaker to OFF (it's a double pole breaker and breaks both +ve and -ve) the 25VDC between +ve and bonding goes away, tells you that the -ve is connected to the bonding somewhere AFTER that breaker. So, this means that on some piece(s) of equipment powered by that breaker there is a connection between -ve and the bonding. As Bill said, this can often be a "meticulous" electrician taking a wire from an instrument "ground" connection to the bonding. A lot of instruments have their "ground" connection internally connected to -ve and that will cause this issue. It could also be that this "meticulous" electrician took a wire from the metal case of some piece of equipment powered by this breaker, and connected it to the bonding. You need to identify each piece of equipment that is powered by that breaker and check to see if there is a wire from it connected to the bonding system...when you find it (them), remove it. None of your electronic equipment should have the "ground" connection connected to the bonding. The bonding is for electrolysis prevention, and is connected to all the metal parts in the boat that are in contact with sea water. It is NOT electrical "ground". Hope this helps Cheers Alan Elyse SM437

Re: 24V+ Isolated Ground Leak
Paul Stascavage
John,
According to Mark, it appears that your statement regarding the readings being correct are correct. I was freaking out seeing house bank voltages (24 V+) between the POSITIVE side and BONDING side, but according to Mark, this is indeed what we should see. I verified that my Masse Test Light is indeed working, as Mark suggested, by jumping POSITIVE to BONDING then NEGATIVE to BONDING and seeing if the respective light illuminates - they did. As Mark explained it, seeing voltage only indicates potential for current flow. Hence, it appears we don’t currently have a leak - no measurable current flow. I’m going to change the zincs and keep a close eye on the new ones. Thank you Bill H, Bill R, John, and Mark for your help. In the end, it turns out I didn’t have a problem in the first place, but you all helped me reach that conclusion, and learn a good deal in the process.

Re: LLC or Corporate ownership of vessel
On the contrary, having the vessel owned by an LLC has many advantages. First, there is the obvious tax advantage. Second, if you are American and you flag and own your vessel outside of the USA, you can obtain insurance where other US flagged vessels can’t. When it comes time to sell the vessel, you can sell the entire corporation to the new owner. This way the new owner gets the insurance, licenses etc. I would never buy a vessel this way, but it is an option. Perhaps the best advantage is the protection of your personal assets should be find yourself liable in an accident or spill of some type. Keep in mind laws change from country to country but all will recognize limited liability.
One of the other reasons we put our Amel into a corporation was survivor benefits. As share holders, we both have ownership. A friend had a lot of trouble when her husband died in a foreign port. She found out the hard way how every country has different laws. The vessel was in his name and they refused to immediately acknowledge their US legal will. The vessel was seized. She had to hire a local lawyer and eventually got control of the vessel so she could sell it.
All port authorities understand corporate owned vessels. If a single super yacht has ever entered their country, then they understand. Every single large yacht is corporate owned. We are BVI owned and flagged and have never had issue with entering.
The cost can vary from country to country. There are big differences. Grand Cayman is one of the most expensive. Some countries require tonnage surveys and vessel surveys. You need to watch for annual fees and filing requirements for the corporation. Also, countries require registration renewals at various times. Some are annually which is a real pain if you plan to sail the globe.
If you have specific questions feel free to private email me.
With best regards,
Mark

Re: LLC or Corporate ownership of vessel
Ron Hynes
I acquired my Amel in the Netherlands five years ago. At the time, American insurance was going to cost me an exorbitant amount. I learned that I could insure with an EU company, one of several actually, for about 1/3 of the cost. The catch, however, was that the boat could not be owned by an American. I then formed a British LLC which has owned the boat since this time. I never had difficulties checking in to the UK, France, Spain, Portugal, the Canary Islands, Matinique, the DR, Bahamas and Morocco. The Italian authorities gave me a bit of a hassle, but I don’t believe it was because of ownership issues. It had to do with the form of certification I had. Things have gotten a little more interesting after Brexit but I’m no longer in the EU and not really concerned about it. Naturally I can’t comment on whether you have difficulties in the south pacific or in Southeast Asia or when crossing the Indian ocean, but I guess you won’t. Basically, you are very much like a merchant ship and very few of those are owned by individuals.

Re: LLC or Corporate ownership of vessel
Ben, We bought BeBe in here 2nd year. She was owned by a BVI Corporation set up by the owner from Cape Cod. She was BVI Flagged and registered (Defaced Red UK Ensign). To set up the corporation in 2003, cost $696, and as I remember it, the annual maintenance of the corporation was between $400 - $500. My records reflect that the corporation was set up by Astra Penn, Dantrust Limited, 49 Main Street, Tortola, BVI (284) 494 4197, d.penn@.... I hope all of this is accurate, current, and complete. Bill

Re: Solar panels stainless steel mounted vs soft panels
Patrick McAneny
Danny , It may not be an issue,as I have a new plan . I would appreciate if someone would tell me if this would work. I presently have three 140w panels on my arch,they are 26" wide ,same as the railing is tall. Could I install a new 370 W panel on my arch and install two of my old panel (8yrs. old )on the rail ,leaving the third old panel on the arch ,then hook them all four together in series. Can you hook panels of different Watts and open voltage together?
I have a TriStar MPPT charge controller 45 amp up to 150 VOC input 12-48 volts , 24V -1200 watts .So I guess the controller can handle the panels . Is there a downside to hooking these different panels in series?
Thanks,
Pat

I’m thinking about putting a new boat into an LLC or corporation legal entity. Has anyone done such and run into issues in a foreign port? Do most customs and port authorities understand these documentations? I would think so but maybe not in smaller nations

Re: 24V+ Isolated Ground Leak
Paul Stascavage
Mark,
Thank you for correcting my statement to John and the education regarding voltage vs current. I am very confused. The bulb on the Masse Test Light is NOT illuminating on either the POSITIVE or the NEGATIVE side although it used to on the NEGATIVE side. The illumination started shortly after taking ownership in 2016. I had the electrician in Martinique look into that negative leak and he said is was a very small current and not to worry about it but keep an eye on the zincs - which is what I have done since. Fast forward the clock to a few months ago, and the Masse stopped illuminating on the NEGATIVE side however, when I looked at the zincs, they were very deteriorated so I decided I should test for a leak with the volt meter. Yesterday I was seeing a very small leak on the negative side of approximately 0.009 volts but I saw 25+ volts on the positive side and that is what got me all worked up and initiated the post. When taking my readings yesterday I went directly from the battery bank to the yellow/green on the rudder post. The testing I did last night and this morning was on the wall (or as you say curtain) behind the Nav Station. At this location, I show house bank voltage on the POSITIVE side and 0.14 volts on the NEGATIVE side with the navigation instrument breaker in the ON position. I am seeing 0.07 volts on both the POSITIVE and NEGATIVE side when testing with the navigation breaker in the OFF position. I’m getting these readings when testing between the POS or NEG terminals and the Yellow/Green Bonding wire on the bus labeled “NAVIGATION” just to the right or aft of the bus labeled “PERMANENT”. You are saying that house bank voltage on the POSITIVE side is normal? If this is the case, how do I properly test for leakage as I believe the Masse Test Light may not be functioning currently?
