If you look at the PW video I posted on the Lexor, you'll see they mention (and show briefly) a display panel that will show the battery SOC. I would be interesting to know exactly how that is working and what it's showing.

The panel in the video looks like the "30 Amp Digital Solar Controller" (GP-PWM-30) on the GoPower site. You can download the manual there, but looking briefly through it, it only has settings for Flooded, AGM and Gel baterries. So maybe GoPower has a new controller to work with the Lithiums on the PW? Or not? :roll eyes:

FYI - according to PW site, Lithiums (Eco-Ion) are now standard

Hello Back,

As you see you are a guinea pig and many of us are interested in how newer features work out for you.

My Lexor TD is 10 years old now, we've had for a year.

it is great. surpasses expectations- I hope your experience is the same.

That's not the one I was referring to. There is an LCD panel on one of the multiplex wiring switch panels. It gives tank levels and other information, including battery SOC.

This one above the thermostat in the middle of the RV? (about 10:20 into the video) Yes, would be nice to know more about how that works.


TNT88 - Can you tell us more about this? Maybe even scan/post from your manual?

MK - glad to hear your enjoying your Lexor. Excited to use ours more.

We used it this past weekend. Just a 1 nighter, unplugged. The batt level never went below 99%. Impressive considering how much the furnace ran. Northern NY, temp in the 30s overnight. Lights and TV ran from sundown till bout 10pm. Didnt use pump, already winterized. Myself, wife and our 19 year old daughter slept very comfortable on the queen bed. Cracked a window for fresh air, turned Tstat down to 50. Slept great. Maybe a hard days work had something to do with it. We went to an old fashioned barn raising.

Bob - I will post some pics of the charge controller during daylight hours.

Not much of a shakedown trip, but we got to use it. Wife is VERY happy with it. I think the swaying and rolling of the class A bothered her.

One additional thought. We used the 3 piece insulated cab window covers designed specifically for the promaster. They were a little pricey but well worth the cost. I think they had alot to do with keeping it warm inside.

Tim

Tim, what 3 piece covers are you talking about?

WGO is supplying a new style of covers - they come from a company called Covercraft. I haven't had a chance to unfold and use them yet - they appear to be insulated and blackout - unlike the mousefur covers they used to supply.

I had ordered a front window cover for my old van based on the reporting by FitRV on their prototypes of these covers, but I didn't get a chance to use that either. So I'll be selling that one I guess.

Thanks. I think others are interested, too, in how it works, particularly what the settings are telling you, how you change what the settings show, i.e. how it operates. If you have the time, a quick scan of pertinent parts of the operating manual would help

There are many others more electrically "proficient" than me, who may have more specific questions on its operation. Wincrasher?

We all know how the solar controller works - the manual is online. It should be charging above 14 volts - ideally 14.4 to 14.6 for lithium, but I doubt it does in a constant amperage mode. The manual looks like it's a standard flooded/agm/gel battery charger and all that entails. If you are topped off, it should be showing the float voltage. Some makers say float at 13.6, and some say no float at all. If you really want to do a test, run your batteries down and see what voltage you get solar charging and if they ever top off. I suspect the solar will never reach 14.6 volts.

The other panel is what we are interested in. What it's showing for battery state and voltage going into it from the 110v charger, etc. I suspect it's rather dumb, as I believe in the FitRV video, he says is shows 95% until it's depleted. In line with what me and ptourin have found with our DIY lithium setup.

From what I saw at Hershey, they should be using the Progressive Dynamics Lithium charger - 9245AL. They are probably using the standard GoPower solar charge controller, which I'm not sure is a good or bad thing, as the solar will never fully charge the batteries and enter float mode.
