The amps remain stable at -.1 to 0 when no power is being consumed, or a steady negative figure when running electronics, etc. When I shut off the chargers, the voltage stabilizes but slowly declines. The main bank voltage will vary from 13.47 to 13.56 (under float). 5 amps, but sometimes reach as high as 1.0. I can be absorbing at 14 amps with the alternator, or floating on the solar panel at near zero amps, and it still fluctuates-as does the voltage of the main bank. The fluctuations do not vary with the amount of current or the source. The twisted pair is a couple inches from the voltage and power leads, except at the shunt and the back of the meter where they must be in close proximity.Īs for un-related parallel wires, I would think their influence would be negated if there is no current running through them, right? When I shut off the battery switch and the main breaker at the panel, I still experience the fluctuations. He suggested I cut off the connectors and just use one twisted pair of the two pairs included. You can buy Cat 5e or Cat 6 cables with our without shielding. The fluctuation persists even when I manually open the relay. He suggested that I replace the twisted pair with a shielded ethernet cable, such as CAT 5e or CAT 6-even though the wiring is solid core and only 24 gauge (which I was originally told NOT to use).īefore I run to Fry's for network cable, are there any other theories?ĮDIT: PS, I'm also using a BlueSeas ACR between the banks. This guy suggested that the twisted pair is receiving interference because they briefly run parallel to, and through the same bulkhead opening as the main battery cables to the distribution panel. The LinkPro read the alternator current as fluctuating similarly to the solar juice. So I disconnected the solar controller, and started the motor. I contacted Xantrex again, and they blamed it on the CruzPro 35 solar charge controller, saying the pulse width modulation is confusing the LinkPro. I did what they recommended, and trimmed 2-3 strands to get the wire into the unit. They told me to replace the twisted pair with 16 AWG twisted 4x per inch-even though the receptacles on the back of the unit are too small to accept that. I noticed the fluctuating charge current reading, so I contacted Xantrex again. The run for that pair is about 8 feet, at most. For the twisted pair set, I initially used 20 AWG stranded wires, twisted a minimum of 4 times per inch. I made my own wiring harness for the LinkPro, and consulted Xantrex while doing so. I've consulted Xantrex several times on the first issue, but not the second. When running current-hungry electronics while motoring and, thus charging via the alternator, it frequently flashes the "Synchronize" message-even if I had synched it at the dock an hour earlier. When the batteries are receiving a charging current, the meter shows the incoming current rapidly fluctuate as much as. It seems to work well, with two exceptions:ġ. Xantrex customer support has no credibility with me, so I'm looking for somebody who knows what they're talking about.
