    Did you ever resolve this issue.

    All these Voltronic/Axpert type inverters have the same issue, they seems switch on constantly, you will see the charge light and hear the fans switching on constantly, which could explain why people are complaining about the increase in utility bills, when using these type of inverters, I have noticed it with Sunsynk inverters.

    Could it be setting 13 and 19 ?
