There was a problem filtering reviews right now. Please try again later.
I notice another reviewer had an issue with the "on" switch. That could be the problem with my unit, as well, but how would I know with the completely worthless, incomplete instructions that list nothing about the requirements of installing the unit?
Save yourself the time and expense and skip this thing. Absolutely ridiculous.
I fnally gave up and contacted Renogy CS and sent a video of my tests, installation, and setup. They sent me an RMA. Once they received the unit, it was tested and they notified me that it worked fine and I would need to pay for return shipping to get it back. After a lot of discussion I did agree to do that but on the conditions that if it did not work, I would want a full refund of all costs involved with the unit and shipping.
Technicians agreed to review the video I had sent before getting authorization to return and noticed the dip switches were incorrect. I did not believe that was true but rechecked and was still convinced they were correct per the manual. Since they missed that point, they did agree to return the unit without charge. I did see the ON indicator on the bottom side of the dip switches when I inspected closely in good lighting. I had the switches set exactly the opposite since I assumed up was on. With the change, the unit worked just fine.
If you purchase a unit, make sure you download the latest manual on the website. It has been changed to reflect the position of the dip switches and a few other clarifications. It is still a little vague on the wiring of the run signal and low current input but much improved from the previous manual. Mostly straight forward however. At this point I am pleased and I only subtracted a star for the confusion on the dip switches. I would give support 5 stars for helping me out however.
Talked to Renogy and was told the temp sensor is not available for purchase yet and they could not provide a time frame when it would be for sale.
