RenogyBluetooth Module RJ12 Communication Port Compatible Rover/Wanderer/Adventurer Charge Controllers, BT-1 RS232,Black

Quick summary: this Bluetooth adapter is simple to install, configure, and use. The information it provides to a phone is very useful and much more convenient than going and looking at the charge controller.More detailed review: I have a Renogy Wanderer 10A charge controller, 50 watt panel, and a LiFePo4 battery to provide 12V power for lighting and a small fan in my shed. I wanted to be able to check on the system and verify it was working correctly without needing to go out in the shed and directly look at the controller, so I purchased this Bluetooth adapter.Connection is simple: it uses a modular connector identical to those used in landline telephones, so it’s literally plug and play.Pairing with Bluetooth on a 2020 iPhone SE is quick and easy, as is using the app. It provides all the real-time status in a convenient and useful layout.The range is enough to go about 30 feet through the shed and house walls. I did test it up to 100 feet away with no obstructions, but it was not able to communicate with my phone at that range. I suspect the range estimates are idealized and somewhat overstated.Useful feature: if the controller’s output is set to manually switch the load on and off when the Enter button is pressed, you can remotely switch the load terminals using the app.The only downsides seem to be related to my charge controller, not the Bluetooth adapter. The controller is extremely basic and doesn’t do any internal data logging or storage at all beyond saving the settings. Thus, the only information it outputs is just the real time status, which the Bluetooth adapter faithfully transmits. The app is capable of many features that this particular controller is not, such as renaming the controller and logging historical data about power generation, consumption, battery state and voltage, etc. I presume more advanced Renogy controllers would be capable of logging and sending that data, though I wish the app would hide the fields and options that the controller doesn’t support.Bottom line: if you have a Renogy controller and want to monitor it without needing to directly look at its display, this Bluetooth adapter is the way to go. In my case, the controller cost less than the Bluetooth adapter, but getting the adapter was definitely the right choice.

I had originally ordered and received a BT1 module from Isunrgey but I returned it for refund because it came with no instructions, no owners manual or owners guide and instalation guide. I did reach out to the seller and they sent me a small sticky note size instruction guide that had more than 7 words printed on it. After receiving this i just requested a refund and returned the item per isunegies instructions. That was on Dec 6,2024 I haven't received credit on my card as of yet, DO NOT BY ANYTHING FROM THIS SELLER. They are dishonest and should be banned from Amazon.The Renogy product I ordered to replace the crappy isunergy BT1 module was less expensive, worked much better and yes it came with detailed instructions and a multi page owners guide. Not to mention the Renogy App is much more user friendly and has much more content. Buy from Renogy, DO NOT BOTHER WITH ISUNERGY.

Minus one star sort of because of Renogy and their stuff is a little confusing for a newbie.If you have an OLDER rover... you need the BT-1. If you have a Rover Li... you need the BT-2 I believe.Buying Renogy via Amazon for ME has been hit or miss. I ordered a starter kit from them and it was NOT clear that they were selling/sending the "out of date" Rover controller. It's not a HUGE deal because it works but Renogy's site has sort of moved on with regards to documentation and information about the thing I just bought last week. Sort of annoying.The BT adapter works well... it even works at decent distances from the unit. I am curious what the power draw is on it.

Cool 😎 to see on phone pull up and you see what is happening to your batteries

Works great lets me know all the info I need to know from how many watts my solar panels are bringing in to the percentage of the battery. the bluetooth range is decent it works up to10-12feet. The device itself is pretty small, won’t take up much if any room, It also comes with a thermometer to check the batterys temperature which was nice. The quality seems good so far. You do have to download an app to use this product but that wasn’t an issue, It was very easy to hook up to my battery and use. overall I’m pretty happy with the product

Works good. Just make sure you get the right one. Some need the Bt-1 and some need the BT-2

does not turn on will not communicate, I am not sure if it is the charge controller of the bluetooth but I am not happy with either products since neither are working and i will be trying to return both.

Original failed, replaced so far still working
