Hi everyone,
I am trying to make sure I understand my Epever Tracer AN SCC correctly, I've read the manual back to front a number of times and searched online to no avail.
On the controller I can cycle between 10 screens, below are the screens and what I understand them to be, please confirm or correct my understanding:
Screen 1 - PV Volts - this should be the voltage of the power coming from my panels
Screen 2 - PV Amps - this should be the amps of the power coming from my panels.
Screen 3 - PV kWh - this is the cumulative power generated by the panels since last reset, this I'm confident in
Screen 4 - BATT Volts - this is the voltage of the batteries minus voltage of loads on the system, if I add a big load I should see my voltage drop and then it should return when I remove the load
Screen 4 - BATT Amps - this is the amperage of the batteries, however I don't understand what exactly this is measuring? The total current flowing through the system? The total current flowing from the SCC to the battery? My SCC has no loads attached to it (they are handled separately by other hardware connected to the batteries).
Screen 5 - BATT temp - if a temperature probe is installed it measures the temp, I have no probe installed so it is hard coded to 25°C it seems.
Screen 6 - Load amps - would assume this would be the current draw by loads but as I have nothing attached to the load terminals on the SCC this reads 0 for me
Screen 7 - Load kWh - I assume this is also a cumulative load draw since last reset however since I have no load connected to the SCC it reads 0 for me
Screen 8/9 - Load timer 1/2 - this seems to just tell the controller what types of loads are hooked up to it and their use profiles however as I have no loads connected to the SCC it is set to 117/2n for me (manual mode).
So with all the above in mind I have a few questions:
Question 1 - Screen 1 and 2 readings should match multimeter volt and amp readings taken at the PV connection terminals on the controller, right?
Question 2 - The controller battery parameter (e.g. boost charging voltage, boost reconnect voltage, float charging voltage, etc) all relate to the reading of screen 4, right?
Question 3 - If my understanding in question 2 is correct then if screen 4 read 12.8V and my boost reconnect voltage is set to 13.2V then the system should enter bulk charging mode, right? Because the battery voltage has dropped below the Boost reconnect voltage.
Question 4 - if I have no loads connected to my SCC then all the low/under voltage disconnect/ reconnect parameters shouldn't do anything as there is no load to disconnect or reconnect?
Question 5 - which screen, if any, tells me which charge state the SCC is in (bulk/ continuous/ float)? Or do I need the MT50 or another connection to see this?
