Amp hour meter wire run...

Any tips on where to get the best price on a cummulative amp hour meter?

I've got a TriMetric battery monitor that I picked up here (Northern Arizona Wind and Sun). Once you program it with the amp hours of your battery bank, it will track cumulative amp hours and indicate percent remaining. I'm pretty happy with it.

You can watch my video review for it.

Got a refund on the ebay one I bought that measured discharge but not charging. This one says it does both - and amp hours to get % charge. $25.

If the wring diagrams are correct you can read one or the other but not both. To read both you would need a switch to change the wiring input to match drawings. To read both you may need something like this one. DC 10-90V 250A Volt Current Meter Capacity Power Charge Discharge

Thanks Westend......

I bought a Victron at Jamestown distributors but I paid less than their current price. They do price match if you can find one for sale lower.

This is another good reason to run your SHUNT TYPE sample in the NEGATIVE side of the battery circuit.

Otherwise you will a HOT 12VDC potential on the DC sample wiring routing back to your meter panel which could easily short out to frame ground and burn the whole length of the wiring back to the battery source.

The USE of the TRANSFORMER (HALL EFFECT) type DC current sample is a much better method to monitor your high currents but they are expensive to purchase.

SURE ELECTRONICS EBAY CHINA had a great $30 purchase for this years back but are no longer available unless you want to shell out over $800 or so... With this unit you just run your battery cable thru the opening and only small low voltage-low current sample signals are sent to the meter panel. No HAZARD potential present...

If it is like all the other Xantrex monitors that I installed before the depression. It uses very small wire between the battery(ies) and shunt and the actual instrument. Distance is not an issue at all.

Presumably requires a shunt. The shunt is usually in the ground path, closer to the frame ground so that you measure all of the DC current passed.

Xantrex Link-Lite Pro installation instructions

I will be using a Xantrex Battery Monitor that will keep track of several things. I'm not sure yet if it requires a shunt, I assume it will. If so, where should it be put? Close to actual meter or near the main DC output?
