Further to my last post, I am not sure I understand how my controller(s) actually work, or if they are not working as they should.
I wonder if someone could explain please.
To test the system, I have the boost set at 13.9V, the float set at 13.9V, and the boost reconnect set at 13.8V, with a boost duration of 45m.
Charge controllers are 12 V Outback flexmax 30s feeding a LA/lithium hybrid system.
I have been expecting the absorption/boost voltage to reach 13.9 V, hold for 45m then drop to a float charge, with zero current.
What appears to happen is that the controller reaches the boost voltage of 13.9 (whilst the battery voltage remains at 13.5V) and then drops into float, but continues to supply current at the same rate as in boost mode.
The first two images are data from one of the charge controllers. The second image is from the Lithium BMS.
Thanks
