Hey guys,
System has been operating for over 9 months, have twice experienced a DC ripple shutdown / lockout. In both cases system was nowhere near full load, at temperature extremes, etc. Yesterdays shutdown appears to have happened around the transition from absorb to float and wondering if that somehow caused/exacerbated a ripple - though it shouldn't be >5v needed to shutdown.
Appreciate any insights! Have double checked cables, but will check each bus bar also. (Battery was balanced before building, shows 0.01v delta between min/max cell during normal use)

++ Blue Seas MRBF fuse holder mounted directly to + terminal on battery
-- Negative bus bar
-- 24" 8awg x 2 soldered to BMS (so both +/- cables are 6' overall)
