Meet the Renogy BT-2 Bluetooth Module! Unlike the BT-1, this new generation of Bluetooth Module is compatible with a variety of products, including Renogy solar charge controllers, smart lithium batteries, inverters, and DC-DC MPPT battery chargers. Connect the BT-2 to the component's RJ45 communication port to wirelessly check and adjust your system's parameters through the DC Home App (available in both the App Store and Google Play).
【Precise Control Over Your Devices】 Compatible with all Renogy RS485 communication port products includes the Rover Elite MPPT Solar Charge Controller, Smart Lithium Batteries, Pure Sine Wave Inverter with Power Saving Mode, and Dual DC-DC MPPT Battery Charger.
【Real-time Insight】 Get real-time and historical data via Bluetooth Module and Renogy DC Home App. Bluetooth 4.2 and BLE technology provides fast and uninterrupted communication.
【User-friendly】 Easily connect the Bluetooth Module to the RS485 communication port, and follow the App instructions. The Bluetooth Module is powered by solar energy, and the ultra-low-power dedicated chip will allow signal range up to 82ft.
Connect the BT-2 to the component's RJ45 communication port to wirelessly check and adjust your system's parameters through the DC Home App (available in both the App Store and Google Play).
Fully control the solar power generation, energy storage, and inverters' real-time operation data by monitoring from the DC Home App.

Title: Works great with the 50A DC to DC charger
Review: Just make sure which Bluetooth module you need for your Renogy device but I’ve used both with different setups in different builds and it’s great. Nice long cord to get it where you spend the most time. Would recommend this add on.

Title: Works great
Review: Just make sure to use the BT app and not the Home app. The Home app is pretty useless if you just have a solar controller and no other devices. The BT app is pretty good.

Title: Functions but needs improvement
Review: Does not indicate if currently connected and displays old data. Does not stay connected, need to keep reconnecting. Small light blue lettering on white is hard to see. Should use darker lettering that can be enlarged quickly.

Title: Super easy to install. Accurate and easy to read
Review: I purchased this at the same time that I purchased a Victron shunt and bluetooth monitor. I plugged this in to my Renogy batteries and am able to monitor both batteries through one BT-2. This is a much easier and less expensive option than wiring in a shunt. Install is as easy as pluggin ethernet cable into the RJ45 jack. If you have a second battery, you need an ethernet cable to go from one RJ45 on one battery to the RJ45 on the other.

Title: Disappointing - I used to be a Renogy fan
Review: My experience with the BT-2 spans over a year. After finding emails for US based staff for Renogy, I ended up interacting (via email) with an Engineering director in China.Environment and background:I'm in California. Prior to the series of activities associated with the BT-2, I had purchased various Renogy products including five LiFePO 100 amp-hour batteries, six solar controllers, ten or twelve solar panels (all at least 100 watt, hard-framed and flexible), 12v DC power 1000 watt inverters, and various cables, tails, fuses inline power meters and BT-1 modules... all to build a few solar generatorsPros:The panels, cables, LiFePO batteries have been behaving fine.All but one solar controller have been fine.Cons:This Ratings link is for the BT-1 and BT-2 modules. Unless the person writing the rating specifies which they are reviewing, it is impossible to know which is being reviewed.There is nothing in Renogy's documentation that says current firmware must be present/active in the Renogy LiFePO battery to which it is connected.Updating old LiFePo battery firmware is challenging, at best.There has been no way, until now, to know what firmware is active in the Renogy LiFePo battery.The BT-2 does not do a lot - it is the connection between the app (smartphone) and the Renogy LiFePo battery.The BT-2 module itself seems to be OK, but the (iOS) app was not so OK. * After accessing the BT-2 app, leaving the app did not tear down the Bluetooth connection. (this was resolved during my year of working through what was originally a BT-2 issue that ended up being a LiFePo battery firmware issue). * There is a "social media" part of the app that is unnecessary. But you can earn points for products. There is no way to know what safeguards are in place from a data security perspective. * Renogy customer service first contact was horrible. Winding through the maze via emails was time consuming, but somehow I ended up with the Engineering Director in China - This person was great. * When the iOS app is connecting to a battery, if "1 batteries" is selected, the app won't recognize that single 12v 100 AH battery. If "multiple batteries" is selected, the iOS app will connect to the single 12v LiFePo battery.(I specify iOS app because I don't know if the Android app behaves similarly.)Ultimately, I ended up sending all of the (in-service) batteries back to Renogy (US) for firmware updates. After a few months, all battery firmware updates finally got done. One of the reasons it took so long was these batteries were all in service supporting the solar generator in which they were installed. I had to replace the Renogy LiFePo batteries with 100 AH lead acid batteries to remain in service to get the updates done. Swap one or two batteries, send them to Renogy to get updated, wait, get the updated battery back, swap with lead acid battery, move on to the next solar generator.The iOS app + BT-2 + current LiFePo battery firmware are behaving relatively well. Getting here was time consuming and frustrating.If you purchased your Renogy LiFePO batteries 2+ years ago and are having problems getting the BT-2 to work, my guess is it is not the BT-2, but the battery firmware version. Good luck getting the battery firmware updated.To top it off, the chronology I had posted with the excruciating detail of the challenges getting through this ordeal was deleted. I did not received any notice from Amazon or Renogy as to when or why. I still like Renogy products, but won't be buying from them anytime soon... Without good customer service first contact, I no longer recommend buying from Renogy.

Title: Kinda Flaky
Review: Neat idea. Love being able to see details of my charge controller on the app. However, had problem connecting initially, and continue to have problems staying connected. First time tried to connect to DC-Home, the app didn't even see it (even though it showed in blue-tooth devices on phone). Second try, DC-Home saw it, but didn't even try to connect. Third try, saw it and tried to connect, but stated "Connection Error". Fourth try... finally got connected. Now that it's connected and on the home screen, staying connected seems to be an issue. Sometimes, the device is grayed out on the home screen and must readd the device. Sometimes, the device appears active on the home screen, but when you select it and go to the detail screen, it fails to show any values (just dashes). Refresh, and it says the refresh was successful, but still doesn't show any values. Have to go back and readd the device to wake it up. Great features... if it would just stay connected.

Review: Wanted to use with my new LIFEP04 Renogy smart battery/trolling motor setup. Power light comes on when plugged into battery and link light flashes but app crashes every time before connecting to battery. Using Android 7 phone (yes, blue tooth is enabled). Tried with DC Home App then Renogy Home app. Unable to connect via BT2 with either one. Researched online forums with no luck, but lots of others have same or similar problems. Submitted ticket to Renogy support but like others, didn't receive a response. I suspect this is a software issue given other negative reviews of these apps but the BT2 is useless with no working app. Returned to Amazon. Update. After 8 days I got a pro forma response from Renogy asking for a video clip of my problem! How do you video an app crashing? I put lots of specifics in my submission and its clear it wasn't even read. I love their LIFEP04 battery but their tech support is very weak.

Review: Although the Model number is the same on my old Blue Tooth BT-2 Monitor, the male plug end does not clip into my charge controller.Perhaps a close up picture of that end might be in order. Would save the return. (Although returning an item couldn’t be much easier)I was excited at the prospect of being able to see on my phone how my small solar array and battery charging was operating. My old monitor worked great, until it didn’t.This is no slam on the product. Just the ability to pick the correct one.
