BT-1 for Renogy

Chris Bowden on Oct 14th 2022

Having installed a couple of DIY solar power supply systems at a remote off grid observatory, I made a similar one for use at home using a spare Renogy “Wanderer” controller with a couple of 110AH sealed lead acid deep cycle batteries. I purchased the “BT-1 Bluetooth Module for Renogy Products w/ RS232 Port” as an add on to be able to monitor the state of charge and battery usage of the system located in my garage remotely inside our home via Bluetooth. The unit simply plugs into the controllers serial port and has a very long cable so the transmitter can be mounted as close to the monitoring point as possible via it’s convenient mounting holes using tacks. With the Renogy app downloaded to my phone, it immediately detected the module and showed a dynamic and animated graphical display of the amount of charge going into the batteries from the solar panels, together with the battery voltage. The data was able to be picked up in our home easily via the long range of the Bluetooth transmitter, despite thick walls in between. Disappointingly however, the unit was unable to transmit the power going out of the batteries via the 1KW Renogy Inverter. I made an inquiry with Renogy about this and they informed me that they are working on a solution for this. For now then, I have to rely on monitoring the battery voltage depletion on the app to determine the rate of discharge which is not ideal. There is however a low voltage alarm that displays in red when the voltage drops too far on tj batteries which is useful. All in all a good addition, but it currently only does part of what I needed it for.
