After putting in a set of new 6v batteries hooked in series my inverter started to hum or buzz. Anyone have an idea what would cause this? Batteries were hooked up exactly like the old set. Thank you
I am thinking you mean converter. Your inverter inverts 12 volt power to 120 for use when you are not plugged in. Your converter takes the power from the plugged in wire, and inside the converter is a battery charger. If it is humming or buzzing, perhaps it is charging your new batteries.
Your converter also powers up all the 12 volt appliances, and it can hum while it is doing that too.
