Hello there.
I have a BMV-700. I dont know what I should change the settings to as I am charging with 3 devices. Alternator, solar and shore.
Please help,

Settings for BMV-700
Hi @EpicAdvanture,
it is impossible for the BMV to differentiate the charging sources, so it should be OK as it is?

Well i didnt chage the settings when i installed it. There is a video saying I have to change the settings when using solar? What is the settings for that? I dont understand what to set it to. Thanks you for the quick response by the way.
Maybe this blog post is worth reading. It covers everything important:

Do you have a link to the video that you saw? Maybe there is something in there that you saw which is or isn't in the same context that would apply to you.
What Markus said is right, there aren't any settings to differentiate energy sources for the BMV.
The victron installation video said that when using solar, I need to adjust the settings accordingly.
the only settings I frequently see set wrong is the 'charged voltage' and 'tail current' settings, this can lead to syncing to 100% way to early.
make sure these settings are appropriate for your batteries / battery size.
Yes, that's exactly the settings I dont know how to set. Can you help me figure that out? I have 3-100 amp hour sealed lead acid batteries wired in parallel . 12 v, 300 ah. @Boekel
because your system can charge slow due to low sun input: have the charged voltage high, like close to the max (absorbtion) voltage, the charged current is tricky, I'd start with 1%
if you really want to get it right, you can choose to not let the BMV sync itself by setting the voltage even higher, this way you can check if the SOC drifts up or down from what it should be (should be 100% when absorbtion is reached and the battery doesn't accept more than x current)
Change charge efficiëncy and peukert factor to finetune.
Thank you. That makes much more sense than the instruction manual. Now what about when charging from my alternator? I have an 180 amp alternator. Will those same settings work?
