This question has been asked before but I haven’t found a answer that fits. I have put together a DIY 24v 8s 280ah eve cell battery. Because I want a 24v 200a BMS my options seemed pretty limited and I had to go with a Dali BMS. Unfortunately that one doesn’t have a temperature sensor.
So I picked up a renogy 30A rover charge controller, with temperature sensor. BUT! It isn’t used for low temperature cut off.
So now I only just got the charge controller so it is probably an option to return it. I would need to get another charge controller that is good for my 800w of solar coming in at 48v and 20a and going into my 24v battery. Or I keep the charge controller and get another way of cutting the solar input with some relay rated for 30a that can be switched off when a sensor in the battery reads 1C. Where I live it wouldn’t get to freezing that often but it wouldn’t take many times to kill it.
The renogy rover 30A was a good price, I would like to keep the setup in the same price range.
