Upper fan runs alot when under very low load and batteries are floating. Ambient temps 66-82 degrees. Doesn't seem to matter what the air temp is. Upper fan also went into lockout/ froze once. Manufacturer says temp sensor on transfer relay thinks it warm. Everything else works very good.

I had one of these units already of the 1KW sort, so I knew what to expect. It works flawlessly, as I expected it would. Our off grid home is that much better for the having of it!! I'm very lucky to have stumbled on to this good deal! Thank you!!
