First post in this forum, thanks in advance for any assistance. My 200Ah LiFePO4 gets down to around 50% SOC after night time usage (Trimetric Monitor) and the following day my Epever controller never goes back into Bulk mode to take advance of the 40A MPPT with two grid-tie panels. It seems go back to Boost mode and then the maximum Boost time of 3 hours is over in the morning or early afternoon. This leaves me in Float mode at the peak charging window, which tapers the amps when it could be filling the batteries in full sunlight all afternoon. I have to shut off at the batteries to reboot the controller to restart the full Bulk cycle, the the amps jump way up to where they should be and it works fine again that day. It's a hassle I should not have to do every day while camping, plus I'm not always around to reboot during the day. This is wasting the capacity of my 750W panels on sunny days. I've tried adjusting the Float and Boost reconnect voltages, nothing seems to work to get it to go back into Bulk Mode on its own. Any ideas?
