Popular Post Spike Posted February 11, 2022 Popular Post Share Posted February 11, 2022 (edited) With the help of a number of good folks on this forum and my great RV Tech, Mathew Gonzales, who has worked on my 2017 Elite II since I brought in home to SE AZ, I finally achieved my goal of being able to run my AC off of my 2000-watt inverter and my new battery bank: 4 100ah Battle Born lithium batteries. After asking for, and getting, advice from folks on the forum about a number of issues that Mat and I ran encountered when attempting this upgrade, I made these decisions and Mat did this work: I first made the decision to purchase the Houghton 9.5K Low Profile Air Conditioner from RecPro--due mainly to how much quieter it runs compared to the Dometic Penguin that came with my Ollie, and to its lower amp draw (10 vs. the 16 for the Dometic). I learned that the Houghton could be run off of the 2000-watt inverter that came with my Ollie, using a transfer switch plugged into it running to the AC. I asked Mat to move the Micro-Air soft start previously installed in the Dometic to the Houghton. We discovered that he needed to reprogram the soft start to coordinate with the new AC. Since, unlike the Dometic set-up that came with my 2017 Ollie, the Houghton did not have a way to control the furnace, Mat installed and wired an Emerson non-programable thermostat--once again using information gleaned from folks on this forum--to control the furnace. I figured it was a good idea to supplement the 320-watt solar panels that came with my Ollie with a 180-watt Zamp solar panel kit. I also purchased a Zamp solar port that Mat installed near the shore power input. When my AGM batteries overheated last fall, I found I had no way to easily disconnect the battery bank. (This, I suspect, is something that is an original defect in the electrical system of my Oliver. Is it for all Olivers still?) So, while Mat was doing all of the other work, I had him install a battery disconnect switch near the inverter. I don't want this to appear as a straightforward process. It took a lot of back and forth between Mat and me trying to come up with solutions to problems encountered along the way. This back-and-forth involved a lot of advice from folks on this forum, some of whom I have not thanked by name. I would like to give special mention and thanks, however, to CnC and Minnesota Oli, who spent a good deal of time with me exchanging private messages. Man, were they patient with this technical novice! The outcome is that I now have a much quieter AC that runs off of my solar, batteries, and 2000-watt inverter. One can read elsewhere about the advantages of the Houghton. Mat told me, before I took my camper home, that he ran the Houghton for about four hours, supplementing the roof-top solar with the Zamp portable kit, and the voltage never dropped below 13 volts. I ran it when I brought the camper home, and verified that the system seemed to run the AC flawlessly AND much more quietly than before. I am delighted, as I have been wanting for a long time to be able to boondock in climes needing cooling of the cabin without having to resort to the hassle and noise of a generator. I will follow up with another post if I run into any issues. Disclaimer: I still have very little technical understanding about how this system functions and how the components and wiring fit together, so I will not be the one to answer many, if any, technical questions, but I know that on this forum, if you ask, you receive. There are some good posts on this forum involving the Houghton AC and related issues, so take a look around, and don't hesitate to submit your questions on this forum. Doing so paid off big time for me! Here is the interior view of my newly installed Houghton 9.5K Low Profile Air Conditioner: Here is an exterior view (birds won't be able to nest in this one!): Here is a photo of how Mat secured and wired the transfer switch and battery disconnect switch: Here is a photo of the Emerson non-programable thermostat to control the furnace (thanks go to John Davies who suggested the purchase): Here is a photo of the Zamp solar port with cord leading to the Zamp 180-watt portable solar panel kit: Here is a photo of the charge controller on my Zamp 180-watt portable solar panel kit, showing the voltage just after I plugged it in. (In less than 10 minutes, this controller and the interior Zamp showed the voltage up to 14.6 before dropping back into the floating voltage range.): Edited February 12, 2022 by Spike Needed to add more info. 3 17 1 Onward through the Fog!
