Review on High-performance Temank 100A MPPT Solar Charge Controller: 12V/24V DC Auto, Max 96V, 1300W/2600W Input Solar Panel Regulator for Gel Sealed Flooded Battery and Load Timer Setting by Kevin Pirlet

I wouldn't use this controller if you plan to use it in parallel with another MPPT controller. I connected this controller and a MakeSkyBlue 60A MPPT to the same battery. In the early morning during bulk loading, everything works as expected. However, once the battery reaches float voltage (I set it to 13.8V), MakeSkyBlue tries to go into absorption/equalization mode (shoots out 14.6V), but this controller for some reason recognizes that the bank is fully charged. , skips the absorption/equalization phase and immediately goes into float mode, meaning the other controller does the charge acquisition itself. As far as I can tell this wouldn't be a problem if the user could manually set a fixed voltage and absorption time, but as far as I can tell neither is adjustable.
