Not a TriMetric, but for $20 might be worth trying out...

I ordered one as well.

I'm sure I'll be back here needing some help on the install :-)

The other day power went out to the entire city. I ended up drawing 242 amps according to the Magnum remote, so I think I do not need yet another meter.

242 amps peak ?
Or
242 amp hrs total ?

242 amps continuous load. I heat electrically and have a Magnum hybrid inverter--so when the power went off the inverter kicked in to keep the RV warm.

To Be Or Not To Be...

HOURS!

That is the question

The word HOURS, AMP HOURS is missing from the above two posts.

242 amps X 12-hours = 2,904 ampere hours. Have a 3-axle battery trailer, do you?


:) ;)

As near as I can tell about 1 hour at 242 amps. But I do not own an amp-hour counter.

My point is, that with a medium to large inverter one needs a meter that would read up to 300 amps. My "high" discharge rate is 276 amps.

Don
the Ebay store where i ordered the 200amp version
has 400 amp and 600 amp versions

basically its the same meter with different programming and a much larger shunt for the larger loads

Pianotuna, exactly right.

Larger shunts naturally widen the resolution band. The + - % error yadda.

The BORG has a pair of 50 ampere shunts. One digital the other analog 50-amp capacity. Kinda wish I waited and used an amp hour meter or better yet a kWh meter.

I am chasing down a USB input, A to D converter with kWh graph plotting. Expandable scale one minute resolution of all three components, amperage, voltage, and ampere hour accumulations. PC powered analysis. I am not sure what software program they use. It's of Indian / Malaysian origin. I like the minute by minute data points. Bi-directional polarity

as it should be

But it should have been made clearer in the first place. :)
