Voltage fluctuations on house batteries

My Heart Interface 2000 shows voltage fluctuations on my house batteries. Anywhere from 14.75-15.35 with rapid peaks and valleys. My chassis batteries are stable at 14.4 with inverter in charge mode. House batteries? not so much. Do I have a faulty inverter.

Are you reading the voltages from a solar controller panel?

I have read it from the voltage display on the inverter and checked it directly on the battery poles with a Fluke voltage meter.

Voltage fluctuations on house batteries

I just wondered if it's during the day and if you have solar panels it could just be from those fluctuations. If it's solar related it would normalize at night
My voltage bounces if I read it off the Rv30d solar controller panel. I'll have to measure it at the batteries when the sun is out and see if it bounces voltages at the battery lugs.

My situation is odd because one bank of batteries is normal and the other is not

Is the battery led blinking? Is it possible you initiated a manual equalization charge?

Thanks for the PDF Manual. That will come in handy for future trouble shooting.
