You measured the battery voltage?

And you fully charged each battery before you put them in series?

Perhaps check the battery voltage at the Multiplus input terminals.

Just in case of a bad connection.

Have you checked the Voltage at the multiplus WHEN THE Multiuplus is under LOAD. And what type and size is your battery bank

@Judd@switchenergy

Did you upgrade the battery cables to handle the extra amperage draw?
