Operation Method
When using Eco or Green modes, the EV-Charger can be programmed to "boost" the
current charge in a certain period. During the set boost period, the charging rate will adjust
to maximum (just like Fast mode), regardless of the amount of available surplus power. This
means that the power may be drawn from the mains grid supply during boost times. If the
EV is fully charged, the EV-Charger will stop charging.

9.5.3 Dynamic Load Balance
The EV-Charger has dynamic load balancing function. During the charging period, no
matter in which charging mode, the total power of the house will not exceed the main
grid capacity. To ensure the total power of the house doesn't exceed the grid capacity, the
charging power will be adjusted in real time following the total load power.
