<p>Hi Steve,</p>
<p>You have always been so helpful over the decades to my business.</p>
<p>I realize this is not for you but Allan. I am sure someone will give specifics on getting this to work. I would only add that most all of these Soc battery monitors used in lead acid have been nothing but a source of problems. Even if they get the calibration at commissioning, they rarely get the recalibration they need to be useful. They are battery killers and I stopped using them.</p>
<p>I teach the user on how to read voltage, note the load, and make a judgement on "when" to recharge. It is not that hard.</p>

<p>Esteemed Wrenches, graybeard (used here as a gender-neutral term) contingent:</p>
<p>I am putting together a low-cost off grid upgrade package for my nearest neighbor out here, who has lived with a most basic system with little upgrade since the 80s. She needs a sinewave inverter to run a modern washing machine. I'm using good older equipment left over from other upgrades: an early narrow FX E-Panel, Outback VFX3524, ProStar 30, circuit breakers (!), etc. </p>
<p>I have a 'Trace Meter Battery Monitoring System' that I'd like to include for her. It's basically a TriMetric variant that Trace purchased the rights to modify and private label from Ralph at Bogart Engineering about 15-20 years ago. I can easily find the installation and operations manual online. But unlike the TriMetric, Trace removed the terminal screw strip on the monitor PCB, replacing it with two RJ6 connectors and a plug-in phone cable. A matching connector was included with the meter that mounted to the kelvin terminals on the 500A/50mv shunt.</p>
<p>I have a (believed to be) working monitor and a bunch of 6-pole RJ6 cables (they were also used to parallel DRs for 120/240, and maybe other tasks as well) but not the matching shunt board. Does anyone know, or can tell me how to determine, which RJ6 terminals are which? The TM2020 on which this meter was based had 4: G1, G2, SIG and +. Also, the monitor also has a second RJ6 terminal for serving as an on/off switch for (probably) the DR. Do you know which terminals are used for this remote switch function, and whether it could also serve as an on/off switch on the inverter by connecting to the remote switch terminals on the VFX (this works with a standard on/off switch in place of the Mate, so it oughtta also work with this switch function, no?).</p>
<p>Thank you for any assistance you may provide.</p>
<p>Allan</p>
