I have MPPT 100/30 and Victron connect shunt with a battleborn lithium 100 amp battery. I diagramed my system same as Farout ride but only have one panel and battery; much smaller system. Last night, entire system dies including connect reader. sun came up today and I have power again but mppt was in float saying batter 100% charge and volts only at 10.89. Victron connect says same thing. Voltmeters as well, 10.89. I tried resetting the mppt and shunt by disconnecting solar, then battery to solar, then negative to shunt. Hooked all back up now MPPT is flashing bulk blue light. I am a novice. Yesterday it was 80 degrees out. Obviously the battery is not charging. Any suggestions?
