I have a couple of EPever SCCs. they are rock solid. The BN is their top of the line and all are programmable for any lithium config you need. The BN is heavy duty with heat sinks and cast aluminium case. The AN seems to be light weight by comparison, but still up to the task. if you are not trying to tax everything you can get out of your supply. these are lower cost and close to "bullet proof".
Victron has a low temp monitor that works great, but those are triple the price while a heater is much less for a high energy system (a minor tax for low temp operation). I have a small Tesla powered system they charge, and it is" Overkill", but --- I feel pretty good with them.
I may be wrong, but I do not think we have to have the "cutting edge" to put a solar collection system together.
Sorry if I have offended anybody.
Gracefully,
Pink
