If I'm replacing my house batteries, will I loose all the data in my Outback Inverter/charger or will the settings hold?
I changed out all of mine this summer and my Outback 2800 kept all the settings. I did not have to reprogram.
You should be able to send Outback an email asking if your model has a volatile or nonvolatile memory. Perhaps the answer is also in your user manual that either you have or online.
