Hello, I could really use some help figuring out the settings I need to use on my BMV-712 for my RV setup.
I have 2 group 24 flooded lead acid batteries, that add up to 124 Ah. About half the time I'm charging them from my RV converter (usually via a generator), which is a Progressive Dynamics PD4045KA. The other half I'm using a portable Renogy 100W solar panel with their Voyager charge controller. I left the settings on the BMV at the default and it seems to work well when I'm just charging off the converter. But when I switch to solar, the SOC often jumps right up to 100%.
I looked into my solar and converter specs and with the solar, the absorption voltage is 14.7V and the float is 13.6V. My converter seems to only do 13.6V. I'm thinking that since my settings on the BMV have the charged voltage at 13.2V, when the solar gets up to the 14.7V for absorption it is setting SOC to 100%.
I'm pretty new to this stuff and feel a bit out of my depth. Can anyone help me figure out what I should have my settings at so that the BMV will give me an accurate SOC with these two charging sources? Thanks in advance!
