Title: Need way to continually monitor AC amps
Post by: Larry Rubin on October 04, 2010, 02:08:52 pm
I have a Xantrex Prosine 2.5 Inverter/Charger and the standard LED control panel which doesn't show AC amperage.  The upgrade "Advanced Control Panel" has much more function and does show amperage but of course it costs about $200.

Has anyone hooked up an ammmeter to continually display the power (at a resonable cost)?

I have added a voltmeter & ammeter to the dash to monitor Coach, engine  batteries and alternator output with toggle switches. I had to run wires from dash to engine compartment and coach battery compartment.

Looks more like an airplane cockpit that a Foretravel dashboard!  :))

OK - the ammeter set up looks like what I would want --- can you share more details as to equipment and installation?  Did you run the wires through the wire chase along the mid line of the coach?

Wow barry that is a great setup. I like being able to remove batteries from the charging setup.

This way I can charge the engine batteries before I put the coach batteries on line to charge.
That is a lot easier on the alternator.

The Prosine Display is the 2.5/3.0 ACS Panel (Advanced Control System)
I added the Prosine digital display showing voltage and charger amps. For me I love it, the original setup is great for the non caring I guess but for me, I like to have a close idea of what is happening.

As Barry has done, there is no limit to the possibilities, if you like, why not monitor both AC lines on the generator, amps each, voltage each, the frequency, oil temp, oil pressure, water temp and water pressure and while your at it, why not monitor the temp inside the generator compartment.

I love monitoring everything, but sooner or later I say the heck with it and just enjoy my digital Prosine LED read out.
Cheers
Dave

Dave, do you remember about how much you paid?  As I said in first post, it seems to go for around $200.

Barry,

That is some switch setup you have!  Wouldn't it be a good idea to label the switches in case you have a senior moment and can't remember what position does what?

I tried to get something engraved but the lettering was too small to read.
But they are obvious for me  ::)

Here is a similar working set up done bargain basement cheap (if the pic shows), one meter for each set of batteries and 1 for the amps in and out of the house batteries.  Also disconnects house batteries from battery isolator, so during daylight I take full advantage of my Solar while taking strain off alternator.

Avery makes labels in clear "paper" that you can print on your printer using "white" color fonts.  Then you can peel and stik on the dash.
Sorry Peter, I accidentally deleted your message.
The print would be way to small to see to do any good.
But they are not really needed as the switches are a no brainer.

Great examples Barry and Robert --- I like what both of you did.  Could you post a little more info as to how you built and installed your meters.  I'm sure that lots of folks would make their own with your help to get them started.

It's been awhile, but I got mine on EBAY.  If I remember correctly I spent less than $60 for everything.  The panel I used was a piece of aluminum Diamond plate I had (from an old tailgate cover).  I mounted them just in front of the drivers side window.  The volt meters usually require a seperate power source, but once my little battery I had powering them died I decided to hook them up to my house batteries via diodes and they seem to work fine.  I connected the shunt to the negative battery terminal to read the in and out amps.  Here is a EBAY link to get you started looking in the right direction.
