3) Manual Grid CV with battery CC mode operation
①
Turn on the radio buttons for “Heteronomy” and “With batt CC” in
②
of the previous
operation.
②
Perform the operations after
③
above.
When charging in Manual CV mode, the current is automatically limited by the
current value on the battery side without the above operation.
The Manual CV mode is useful when I want to control when
charging and discharging. In particular, the Manual grid CV with
battery CC mode seems to be used for boosting fuel cells.
However, switching between charging and discharging must be
done from the external controller, so when there is a power
outage or sudden cloudiness, switching from charging to
discharging may not be in time, the grid voltage will drop, and
EZA may stop due to Heavy Alarm….
