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

I see it has two versions, 0-20A and 0-100A. The 0-20 would prob be more accurate in that range, but 0-100 would be more useful I think.

Ok, but I would go for the 100 amp version.

I have one and it worked well. I just replaced it with a Trimetric because I wanted more features and accuracy when I add solar.

These showed up on here a couple weeks back. Looks interesting for sure... I'm not real keen with the DC SHUNT idea especially if used in the POSITIVE SIDE of the batteries. To prone with HOT wires routed everwhere...

I see the AC VERSION uses the HALL EFFECT coil method - Now this I would love to see being used on the DC side..

I too would want the 100A version... My three battery bank likes to draw around 53AMP DC when first being charged... I currently have a +/- 70A Hall Effect meter installed in the line feeding my batteries and this is great as it shows the load current and the charge current with a + or - minus symbol. Been looking for these to start showing up again...

The TRIMETRIC would be a good unit for my install as it supports a settable DC alarm state. I like to monitor my batteries and would like to have an alarm go off when I start seeing around 12.0VDC when running off my batteries. This gives a good idea I am starting to get down close to the 50% charge state on the setup...

For $20-$40 sure would be something to play with. The display has all you need to watch on it... Wondering how bright this meter is going to be. I installed a three LED meter panel (two DC Voltmeters and one DC Current meter and it was so bright I had to add ON/OFF switch on it. Lit up my whole trailer at night...

The shunt goes on the negative side of the battery and the display is plenty bright. My only negative comment is the push button on the front and how it works with the display, not real intuitive, but for the money it does a good job. I checked mine for accuracy with a high quality DVM and it was pretty accurate. $16.00 and free shipping with Amazon Prime.

eBAY has them too

The main problem I see with this unit (and many but not all of the digital DC ammeters available on Amazon etc.) is that it can only measure current in one direction. You can monitor battery charge current or battery discharge current, but not both with the same device, at least without an external switch to reverse the shunt sense lines.

I have hall effect meters for my dc loads and it does measure "both ways" as when I'm drawing out it reads negative. Limit is 70 amps.

I know there are several on the forum that have these, hopefully someone can chime in. It would be silly to have to put a switch in the shunt line to monitor the other direction.
