My Victron 602 has never done a good job of showing the state of charge correctly. It seems to accurately reflect the amount of current leaving the batteries, but does not accurately reflect the charge inflow, which it under reports. For instance, I will use 200 amps of power, it will charge all day, with the solar system showing production of 240 amps, the battery voltages are fully up and the system goes into trickle, but the 602 will show that I have only replaced 150 amps and I am still 50 short. Over several days, this error can become quite large. Sometimes it will fix itself with the settings to sync, when the charge rate slows enough, and I can change these settings to sync more liberally, but I would prefer accurate data. Thoughts?
