BT-1 Bluetooth Module for PWM Charge Controllers (Wanderer/Adventurer) – RJ12 RS232 Port, Wireless Monitor via DC Home App,IP54

They always seem to build good stuff I hooked it it paired with the phone easy and give me all the info I need

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 added this to our rover solar charge controller and it works great. I can monitor battery usage and incoming solar power anytime I’m within Bluetooth range and it has been extremely useful. Installation takes two seconds to plug it in and it’s on.

I have a Renogy charge controller and decided to get the BT module so I could monitor charge status away from the main display. The app, I am not impressed with, it can be quite annoying. I get random disconnections, have to restart it sometimes as it just freezes and a few other things, and this is not miles away, this is all within 30ft. I am sure the module is fine, it is the app that is a mess. When it works, it works, but when it does not it gets real annoying fast. Just FYI...

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

This Renogy BT-1 Bluetooth Module is a must-have accessory for anyone with a compatible Renogy charge controller. It's an absolute game-changer for monitoring your solar power system. The setup is incredibly simple-it just plugs into the RJ12 port on the controller. Once connected, it syncs seamlessly with the Renogy DC Home app on your phone. This gives you instant access to all your system's data without having to be right next to the controller. You can check battery voltage, charging status, and daily energy production from anywhere. It's a huge convenience and makes managing your solar setup much easier. If you want to keep an eye on your power system without the hassle of a physical display, this module is an excellent investment.

This is basically a required item if you're going to use a Renogy Wanderer charger. The charger provides no information other than a few flashing lights so if you want any technical information on solar charging Ah or easily confirm that your array is operating near it's designed capacity then you need this Bluetooth module. Unfortunately, you need one of these modules for each component in the system. So, if you have two solar chargers then you will need a BT module for each which is the biggest negative to the system. My review is based on this piece of hardware. The app that supports it is pretty lousy and hopefully Renogy overhauls it soon. Likewise, the methodology Renogy used for connecting and monitoring multiple components is not the best in my opinion. I recently installed two 200W Renogy flexible solar panels on a camper and used a Wanderer controller to charge the battery. Connecting to this BT module is as simple as an old landline telephone. The RJ12 cable plugs into the BT module and the other end plugs into the controller. The BT module came with an adhesive backing which I used to secure the module to the wall in a corner to keep it out of the way. You can also put screws through the slots on both sides. After a 3000+ mile trip it is still secured to the wall using the adhesive. The app can hang or do weird things but if you close the app and reopen it, it usually connects to the BT module within a few seconds. This module will send a strong enough signal that I could stay connected about 50ft away. I could check the solar charger from the passenger seat while we were driving down the road which is roughly 30ft.

I have a 500 watt Renogy off grid system installed in 2019 located in a barn. Panels, battery, inverter, charger, and a BT-1 plugged into the charger. The first BT-1 failed in fall 2022. Since it was out of warranty, I bought a replacement from the Renogy Store on Amazon and restored the system. In May 2023, I found the second unit to be dead. Both the power and blue tooth indicator lights were dark while the rest of the solar system was operating normally. Since the second one is only 7 months old, I tried to make a claim on the 12 month warranty by going through the support portal on the Renogy web site, as advised by the insert in the product package. Over about a week, the warranty experience went like this: I filed a ticket on their support site and included a copy of the amazon invoice. They sent some troubleshooting tips that all failed since the unit was dead. They requested a movie showing the unit with the lights out. I sent it. They could not read the first movie, so I sent it again. That one they read. They then announced the case was turned over to some internal tech staff. Then they announced they were sending a new unit and wanted me to confirm my address. Which I did. Then they announced that they only warranty units bought from their web site and would not send a replacement. They suggested that Amazon would warranty it. Really? Now, the fact it came through Amazon was clear since I furnished the invoice with the original claim. And the material in the Renogy box says I went through the correct channel. So, I told them to stop wasting my time and I would simply buy the replacement and avoid any further Renogy products in the future. They are fine with that. If you are also fine with it, buy Renogy. Me? If this 3rd BT-1 also fails, I’ll buy someone else’s charger that doesn’t need it. I have about $2k invested in Renogy products. For a $30 failed part, most sellers would simply replace it to maintain the customer relationship. Not Renogy. For about $30 I got to see how they really operate, which in my book is a pretty good trade.

This adapter complements the Renergy Wanderer 30 Li charge controller I purchased. I recommend purchasing the adapter for this charge controller due to there being no display, just some flashing LEDs for status. The adapter seems to work well. The lead is very long. I assume is is so it can be mounted a considerable distance away from the controller if the controller was mounted in an electrical cabinet. In my situation the charge controller is mounted directly on my folding solar panels so there was no need for such a long lead. The app is OK but not great. On Android as soon as the app loses focus it needs to be reconnected. To do this the app must be closed and reopened. I found the BT range on the adapter is fairly standard for BT: about 5m, maybe a little further.

El aparato funciona bien mientras me mantengo dentro del alcance del Bluetooth, sin embargo eso es lo mejor que puedo decir del aparato. Hay 2 aplicaciones para usarlo pero ambas son tan básicas que apenas son útiles, funcionan para ver el voltaje, carga de batería y el estado de los paneles pero solamente mientras estoy cerca, la aplicación no almacena datos así que si estás lejos no sirve para nada, tiene gráficas de la energía que produce pero solo muestra el maximo/mínimo por día, tampoco muestra la variación durante el dia. Todo lo anterior es en la aplicación vieja y es lo mejor que podrás conseguir, la aplicación nueva muestra exactamente lo mismo pero con otro diseño, además la nueva te pide que a la fuerza crees una cuenta con ellos pero no tiene ningún beneficio, funciona igual que la aplicación vieja aún que aquella no pedía información personal. Además la aplicación nueva incluye un apartado que es solamente una tienda para venderte más cosas.

I added this Bluetooth monitoring system, and it has been working perfect. I can monitor the system remotely. Recommended. I just want to say that I paid in full for this product and my review and recommendations are in base of my own experiences.

Doesn’t work

I don't need to open my case to see if everything is working just turn to the app on my phone Tells the voltage current and charge power for the solar panel and info om battery status like capacity, temp, load very happy
