HOME BACKUP Mode
HOME BACKUP Mode keeps the storage batteries fully charged at all times. Once charged, the system goes on
standby as a safeguard against power outages on the commercial power grid.
The display may not show that the storage batteries are fully charged due to a margin of error.

MAX POWER EXPORT Mode minimizes use of "peak electricity" and
"purchased electricity" by charging the storage batteries at night when
utility rates are low and discharging the stored power during the day
and evening to run connected electric appliances.
