I have a Victron Energy BMV-700 Battery Monitor on my solar power system. For quite a number of years the alarm system has very rarely gone off. However since the lead acid battery placement change (originally in 2 rows of 12 batteries but now in 1 row of 24 batteries and only changed to make it easier to see all the battery levels) a couple of months ago I am constantly getting Low Battery Alarm alerts and the system shuts down.. The battery level has normally been between 70% and 90% when this occurs thus making a mockery of "low battery". Sometimes this is happening 4 or 5 times a day (normally it happens at least once every day) & it is driving me demented not knowing why nor being able to resolve the problem.
Any ideas/solutions would be gratefully received. Thank you
