Epever 40 amp mppt delivered

I need help...

I installed the unit and did a prelim test. I have yet to run the controller inside the camper..

So for my test I hooked up the panels in series. Waiting for the combiners to do parrelel.

I ran a 900 watt toaster oven as a load.

58 volts from panels
359 watts
6 amps

27 amps into batts
batts down 12.7. ( had it lower with draw at times 12.4 say.)

I cant get unit to go into boost or bulk mode. I am in user mode and changed the parameters. I though I had them right. There is something I dont think I set right or unit is not working properly..

It seems with my test it never left float. Possibly it knows the AH of batts and knows they are not dead??

Im not sure what all settings mean

Here is what I have.

Over volt disconnect 16 volts
Charge limit voltage 15
over voltage reconnect 15
equalize charge 14.7
boost charge 14.4
float 13.2

here is what im not sure of.

boost reconnect 12.9
low volt reconnct 12.2
under volt warning reconnect 12
under volt warning 11.8
low volt disconnect 11.5
discharge limit volt 11


settings

ah batts 150
boost time 120 min
equalize time 15 min
