Comcerning ladders, I have one of these that we use inside the house. It collapses into a very small size that could be easily stored in an rv:

I added a second piece of 5" plastic fence post under the trailer. The first is used as a replacement for the sewer hose holder so I could use a heavy duty hose.

Solar questions

Let me start by saying that my primary interest is to draw conclusions from actual measurements, and I don't have one controller, much less two, to play with. But I'm always willing to guess...

The "which-is-better" question depends on many variables. For example, are the controllers absolutely identical output - voltage, amperage, charging algorithms, etc? Plus, how do they respond to different input voltages from the panels? Just too many variables.

I'm not sure how blocking diodes come into the picture when talking about
controllers. To my way of thinking, a controller should not allow reverse current to flow - without depending on a diode. But I could be completely wrong... Maybe a diode is necessary to prevent one controller from fooling the other?

Personally, I would go with a single controller with the two (or more) panels combined in parallel before the controller. If nothing else, it would be cheaper.

I can say with some certainty that a controller in the bulk charge mode (maximum charge) can be modeled reasonably well by a low value power resistor. Meaning simply, a heavy load on the panels, pulling down one panel in favor of the other due to sun angle, panel size, shade, etc. If the controller is not in maximum charge mode, say float or equalization, then the load is light and it doesn't matter that one panel is not playing its part. Or to say it differently; adding more solar won't charge an almost full battery any faster.

Hope that helps.

I am getting serious about having Escape install the solar panel and charger . I am solar ready . Will be close to Escape factory and feel comfortable having them do the job . I currently do have a 80 watt go power folding panel . Also have old 1000 watt Honda generator just pulled out of moth balls . I really want to just go solar . I have dual 6 volt batteries also . Now Escape has changed to I think Samplex or something like that 150 watt panel and their controller . I am more familiar with the go power which is 160 watt . I know the controller is important there is a Blue Sky or Morningstar are they better .? What about the new panel or would it better to go with go power ? I want to use folding if needed also . If Escape doesn't want to get me the gopower I could bring it to them or go with what they cur renting use ? Have talked to Tammy about a installation but not the details yet . Don't want anything complicated or pricey . Just a decent system . Also do not want any China stuff .
If anyone could chime in with their thoughts about this I would really appreciate some advice about this . Pat

Good luck on no China stuff. 6 out of the top 10 manufacturers are there. I think both American ones in the top 10 are owned by German companies, but there is a Canadian firm in there too.

Had dual 6V on 17B w/no solar; now have single Group 29 12V and solar package. No comparison- works fantastic however we tried to use the fridge on DC in full sun while driving and after 1 hour the monitor indicated the battery at 3/4. That is the same as one week of clouds/rain so that doesn't seem to work.

Pat, How depth do you want to get in user settings? There are better units but they take some effort to learn proper setup. Plug and play they are not.

From a quick glance the Samlex SCC-30AB (if that's the one they are using) looks decent, I'd ask ETI why they changed. One concern if you want to use both the roof top and the portable panels, the input lugs are pretty small. The manual says they accept 10-12 awg as opposed to 6 awg on the GoPower.

I can't today but I will ask why they changed I think because it would match better with the inverter that use or something like that . Can I use the roof top and my portable too ? When you talk about manual is that for the Samlex ? Pat

I think Jon has used both the roof mount and a portable together, don't know of anyone else. I was looking into it and figured I'd add a 2nd set of leads off the INPUT lug on the controller. and NOT use the controller that's mounted on the back of the portable so I'd need enough room for both. Changed my mind and if needed all add a 100W to the roof.

Should I hold off for awhile ? Article says First solar , Japan's Solar Frontier , Sharp gearing for the market . Is Sharp Made in Japan ? Where is First Solar made ? Who makes Go Power ? Samlex? Thanks Pat
