Multiplus 12\3000\120 output frequency 45hz

Just installed a multiplus 12v 3000w to 120AC inverter charger on a boat. I'm using the mk3-USB interface to adjust settings. The inverter output frequency is set to 60hz, but its showing only 45hz on the output. This happens when running off 12v 500ah house battery bank. Please help!

Hi @LOUISE,

when on shore power, output frequency is always input frequency.

Thanks, I just modified my post to say that this happens only when running off the 12V battery bank.

Understand. Although your screenshots showing that shore power is connected. And this could be a possible cause.
