Whoa, the Xantrex has a 3 amp standby, that's a lot more than the Magnum!

The Magnum is rated at 30 watts, which is ~2.4 amps, so not a lot more, plus the Magnum is termed "typical", which is code speak for "could be more".

I've had no problems getting all but the RS series repaired at my closest Xantrex service center. They are pretty proprietary with their info though.

Chris:

After reading this post of yours I decided to get real time data from my install. I have a Magnum MS 2812 with a TriMetric 2025 battery monitor installed correctly.

The real time data provided by the TriMetric shows the the MS 2812 when 'shut off' draws just about 0.3 amps. When I turn on the inverter and it is 'hunting' or as the factory remote says "Inverting" with no load on it the Trimetric reads a draw of 0.7 amps.

This is why I stated "whoa" in my post. Being a Magnum owner and user I can tell you that what Magnum states in their literature and how the inverter actually performs are two different things.

On the other side, the Magnum literature states the charger side as 125 Amps. In reality it makes 105 Amps

Boonhauler,
That seems to be a significant error on someone’s part. Are you sure all loads are going through your shunt? I experienced this when I installed solar. My trimetric did not agree with my solar charger output. It even made me question the Xantrex C35 output reading. I fought this for over 6 months to the point that I even replaced the C35 with a Rogue because I thought the PWM charger was costing me 30-40% of charge. Humm, the Rogue was costing me the same loss... We even discussed it here and on AZ Wind and Sun forum. I even bought a clamp on DC ammeter and verified the difference. With my clamp on ammeter I started measuring every DC load. What I missed was the negative cable going to the generator starter directly from the battery negative. At the generator it was also frame grounded. This was allowing some load to bypass my shunt. The fix? I simply lifted the generator starter negative from the battery and walla! My world was now in equilibrium. I never needed the Rogue but in retrospect, I like it far better than the C35.

CJW8:

Respectfully, I have installed the TriMetric correctly as I mentioned above. If you're still doubting my installtion then please take the time to follow the link below where I've chronicled the building of this power system / load center. You'll need to read through five or six pages to see the entire build. It's been properly installed and I don't make those kinds of mistakes. All the Negitive power runs through the shunt. The frame ground is prior to the shunt on the return path.

I'm far from perfect but I've painstakingly been extremely anal during this protion of the build. BTW I trust the TriMetric way more than I trust the Magnum Remote.
