Link 2000 Battery Monitor is Flakey

I installed a Link 2000 Battery Monitor/Invertor controller about 4 years ago.

After replacing both the chassis and house battery banks this Summer, it appears that the Amp % (remaining) and Amp Hours reported are not accurate.

1. Amp % is -504 and Amp Hrs rapidly builds to -1500 hours when the inverter is in the Accept or Float mode.

2. The LoBatt signal continues to flash on the meter.

Battery voltage reported matches the multi-meter reading at the battery terminals.

I have:
a. done the Microprocessor Reset Procedure several times.
b. restored the Factory Default several times.
c. reset the Amp Hours to zero several times.
d. reset the functions several times.
e. reset the Battery specifics.
f. verified that the color coded wires are correctly connected and applied to the correct spots on the Shunt.

The Link 2000 controls a Heart Freedom 25 and is supposed to report on a House wet cell Battery bank of 440 Amp Hrs.

Basically, it functions well as a volt meter and inverter controller but not as a Battery monitor


Has anyone had this type of problem and any success in correcting same?

Good question; I would call Xantrex about the issue. They can tell you how to diagnose if it is the shunt or controller.
