FAQ

A
The basic mode charges the battery when the PV generation is greater than the load. When charging
is completed, feed-in is made toward Grid. When the PV generation is less than the load, the battery
is discharged for the load. The items in smart mode are the same as those in basic mode except for
one item. When the daily generation is expected to be high enough, if the PV generation in the
morning of the day is greater than the load, the product does not charge the battery but feed-in
starts toward Grid. (Note that battery discharging is not performed.) However, in the afternoon,
battery charging is to be made. The smart mode has been designed to avoid the situation that feed-
in is decreased according to the local feed-in limitation.
