Ok I've already asked this question but again I have 2 mppt solar controllers that at dusk and only at dusk will give code 38. With out fail. I have only received one answer that did not solve problem I was hoping to get a victron support person to answer my question. They are 2 150/85's ties the the cerbo gx and unless I turn off the solar panel breakers every night they code out. What is causing this. Have installed many controllers and until the last 2 systems have never had this problem.
