What am I doing wrong?
I have the relay set to go on/off with the virtual load. If I use the Always On or Always Off setting for the virtual load, the relay (and therefore the actual physical load) clicks on and off nicely.
What is not happening is that I am expecting the relay to go on/off with the Conventional Algorithm #1 with (36V, 3x LiFePO4) values of: OFF < 38.0V, ON >39.0V. In fact, I have used a variety of voltages, none of which cause a change in the relay.
Here is a plot of the battery voltage that I think shouldn’t really happen where the load should turn off and stop draining the battery at about 6.30am
This is firmware 3.16. Products all bought recently, so should be up to date and seem to be fully working apart from this issue.
BTW, I have just add more batteries to make it a 48V system and it still behaves the same with appropriate on/off voltages
