Hi hope someone can help pls
My new bmv712 just jumped from 92%soc to 100%.
Its first thing in the morning, my solar panels are just starting to make power. I think the problem is, it's seeing the low amps they're making as a tail current so thinks the batteries are full.
Is there a way to fix this? Have I got something wrong in the settings?
48v system of AGM batteries
Thank you
Your tail current is set to 1%. This is 3.23 amps on your system.
It will help if you increase charge detection time and charge efficiency, maybe 95% for efficiency. Time depending on local conditions.
Also take a look at discharge floor. This won't affect the graphs, but will give a false impression of usable capacity. For lithium, probably best to set it at 10% or slightly higher.
After a bit a sun the batteries actually reached 100% full , charge controller went to a low amp float, victron shunt reads 100%soc
I'm a happy man . I'll give it a few cycles and play with the settings
Much appreciated
