I use this to switch my MPPT controller on and off by changing the max charge voltage setting. I have set my own User profile for charging my LiFePo battery. It works with my BT1 dongle. That’s in the motorhome wardrobe and I can connect from about 4 meters away. As it’s on my driveway, I don’t have to go outside!
I find it really very useful. So much better that trying to do stuff on the controller itself.
It shows me the panel’s present output and the present level and mode of charging. Volts, Amps and Watts. It’s not perfect as it always shows capacity as 100% but it’s so useful otherwise and, anyway, I can deduce that quantity from the voltage displayed. I’d be lost without it. Maybe they have improved it and/or the BT1 dongle since the bad reviews, here?
(I couldn’t get the DC app to do anything useful!)
