Automatic Grid CV mode
In this mode, charging is performed when the grid-side voltage exceeds the target voltage.
If it falls below, it will discharge. EZA charges and discharges so that the grid-side target
voltage is maintained. This allows EZA to connect to the grid side and maintain the grid side
voltage regardless of other power supply conditions. For example, when charging with
power from a solar cell, even if the sun is blocked by a cloud and the output of the solar cell
disappears, EZA automatically switches to discharging from the battery to supply power to
the load and operate It is possible to continue.
Operating Characteristic
Note that in this mode, if a power supply that controls the voltage on the grid side
is connected in addition to EZA, it may interfere with EZA and control as intended
may not be possible.
This mode is also recommended in combination with small wind power and small
hydropower.
In EZA11K, the Grid Limit Current can be set to different values during charging
and discharging.
