REC has just introduced a new WiFi module that will connect to your new or existing REC Actve BMS, and the Q/SI Series.
This nifty little unit will allow your to monitor and even re-configure your BMS, all using a simple browser.
And if you add it to your subnet and you have a WAN connection you will have access to your system from anywhere!
We are expecting an April 2021 availability for this product in North America
