Xantrex Link 2000 controller problems

I invested in a Halberg Rassy 46 from 1997. The boat was handed over to me in April with 4 new 160 Amps AGM batteries. They are configured as one 24 V battery bank. They are charge by a Freedom 10 inverter/charger controlled by a Xantrex Link 2000 controller. I have reset the controller to factory settings and configured the battery capacity to 320 Ah. My problem is that the LINK 2000 is not able to charge the battery correctly. It offend show Lo Batt, it is not able to calculate battery capacity correct, AMPS show strange large negtiv numbers when only the light is turn on and it is fluctuating up and down . The shunt is wired as one battery bank but when I read voltage at the display Batt 1 = 28,1, Batt 2 = 27,6 V and my multimeter show 27,8 direct at the battery when then have been charge for 24 hours without any load and 30 min after the charger is turn off.
Please help me do I need to by a new charger/inverter? Or do you have any idea about what is wrong

What is the ah showing for both batteries? #2 is probably way down. You have to use both shunts or it will slowly creep neg on the screen and give you low batt warning. The warning is based on ah not voltage and could be either battery.

Or your shunt is wired in the wrong spot or incorrectly. since you said it always shows neg. yet your voltage is high.

Re: Xantrex Link 2000 controller problems


Thanks for the advice. I look at the consumption and it is between 180 and 220 AMPS, iven when every thing is off. It look like something is wrong with the cable from the shunt to the Link 2000 or it is the shunt. I don't look like the cable are coroted, but ofcause they are 18 years old. Do I need th Invest in new cable or a new shunt? When I disconect the cable it go to 500 AMPS, and if connect batterysite and ground site direct at the LINK 200 it go to 0 AMPS. From this point it looks like it is working. But when connected to the shunt is show strange figurs.

Re: Xantrex Link 2000 controller problems

One of the first things I did when I bought my boat in 1996 was to install a Heart Freedom 25 with a Heart Interface Link 2000 - this was before the company was purchased by Xantrax. The Link 2000 performed pretty well but as it got older, it became cantankerous and sometimes confused. (Just like some people I know). Xantrax quit offering support for the product many years ago and we managed to stumble along, often not knowing what our batteries were doing other than being able to see the amps going in or coming out and the voltage.

Just this year, while in Thailand, a marine electronics dealer made us a terrific offer on a Victron he had ordered by mistake. Unceremoniously, we dumped the almost 20-year old Heart inverter and installed the Victron. The Link 2000 still occupies its spot at the nav station but does nothing more than give the voltage and cover a large hole.

I would suggest you give serious consideration to installing new equipment.

Fair winds and cal seas.
