Yep, the LEDs are what I was referring to.  I think the voltage actually indicated about 12.2v.  After looking, not sure my converter is a Xantrex?? It is the 45 amp conversion from Best Converter.  The batteries are group 27.  The M20 does have a temp sensor but it's too short to reach the battery.  I figured splicing the lead was not an option so I have it run out under the floor near the battery support so it actually is only reading ambient temp- not the batttery temp.  I'll tell the wife you suggest going fishing to help make the system work- that's my kind of advice!

I finally got my system installed and working-kind of.  I mounted a second battery on the RV as well- (not sure if that's the problem or not.)  I used the #10 wire from the PV to the controller and then ran #6 wire from the controller to the battery (about 10')  System output on a relatively sunny afternoon shows about 5.5 amps and the indicator lights on the BZ Model M20+ indicated full charge at sundown.  I have a battery disconnect to isolate the battery (and now the PV system) from the converter/charger. After resting overnight with the isolation switch open, the indicators show about a 25% drop in voltage?  The batteries were purchased on the same day early this spring but only 1 was actually mounted- the other one has been carried as a spare and only used a couple of times.  2 questions- first, is it possible the batteries are in significantly different conditions in just a few months with different operating conditions and would that cause what I am seeing?  Next is how do I "equalize" the batteries with either the PV controller or my Zantrek (sp?) charger?  I see how I can adjust the float voltage but that won't give me a high enough voltage for equalization will it?  This project is really starting to cut into my fishing time- thanks for the help.

Thanks!  I didn't find that one but I did find a similar one that included 3 breakers and an inverter.  That's what I thought but wanted to be sure. 

OK, I got the kit but without any detailed instructions, I'm a little lost with the 15a DC breakers.  Should I wire the controller between the breakers to provide a DC disconnect 1. between the PV and the controller and 2. between the controller and the battery bank?  Need help quick- headed for the mountains soon!  Thanks

Not much activity on this board it seems.  I have a question possted about an RV kit but haven't gotten any response.  A friend who is experienced in installing and designing PV systems suggested altE as a good source for components.  I'm trying a pre-bundled kit.  Good luck.

Anyone have any experience with this kit?  Using the calculators here, it will meet my needs on my RV.  You guys that know what your are doing, does this kit make sense?  Thanks
