I'm sorry I haven't gotten back quicker guys but I've realized how little I know about the electrical system
on board this new to me boat
. I've tried to gather some more info and knowledge but it seems the more I read the more confused I get so please bare with me on this. I'll try and get as much info on this so I can as the right questions. My original question was what I thought would be a simple yes or no answer so let's start with an equipment
list then see if I can fill in any other questions.
I have 12 AGM
batteries for a total of 144v and 3 house batteries.
I have an HFL 15kw dc generator model #E v1505-EU1
The Generator output at 157v and 15kw is 95a and at 172v, 87a. The output is controlled by a rheostat at the control panel
and normally set to 164v. The generator has to be manually started to charge the batteries and the rheostat set to 164v per previous owner and the book.
I have a BRUSA Model #NLG5-11 charger
. for the 144vdc batteries.
I have a DC-DC converter(144v to 12v) CENTAUR by Victron Energy to the house batteries then on to the house panel.
I have a 6kw Inverter
from 144vdc to 120vac to the house ac panel.
All of this goes through a main Distribution Box including the 2-ST 74 Solomons electric
At the helm
I have a xentrex Link-10 and 2 amp meters, 1 for each engine and used some what like rpm
gages to insure equal load. On Thursday I went down th the boat
to do a few things and the reading at the nav station gauge for the battery charge was 148v which should have been at 164v. I checked the battery indicator at the Brusa and the batteries were not charging. Turns out the shore power plug
(new one at the box) wasn't fully seated and it worked it's way loose so I wasn't charging with the frig and freezer
on. I also see that the links-10 indicator is showing low battery as well as 2 of the 4 selection readings is also flashing, the V and Ah then the A and T. The batteries are fully charged now but the Links-10 is still showing only 1 indicator on the state of charge. Any help on this would be greatly appreciated since it's the main gauge I'm looking at to insure I start the generator to recharge.
I'm trying to get a grip on the system so I can get a better understanding of how to approach the redesign of the control systems. I want as much automation and warnings to insure I don't damage any expensive equipment
I have. From what I've been told a lot of the parts
are very good ones, they just need better controls. I'm also dealing with an owner who made several changes but hasn't fully disclosed them. A designer/inventor who no longer works for the company that is selling his design, a company who seems to not want to deal with an older design that was built by a D/I who doesn't work
for them any more.
This coming weekend there is a Lagoon
meet in Annapolis
and I'm sailing up on Thursday. I'm hoping to meet with a rep from Lagoon
as well as another owner of a 44E boat that I can suck up some info from as well as see what changes are being made to the newer boats. By the way last weekend My lovely wife and I had a great day of sailing on Saturday and didn't start the generator other than to exersize it before leaving out of Solomons, MD. Life is good. It's just these little things...
Again thanks for your help guys,
