ECO Mode
The ECO mode can be selected if the user wants to charge only by solar power. It’s
recommended that the solar power has an output current above 6A when selects this mode.
x
If solar power is not connected to the system, do not choose ECO mode for charging.
1. A Current Transformer (CT) device
must be connected between the solar
system and the charger to monitor and
control to supply of power to the
charger from the solar system.
2. If the CT detects that the current of
solar power generation is above 6A,
the vehicle is charged according to the
solar power generation current, and the
max charging current does not exceed
the max output current of the charger.
Figure 30 ECO Mode Selected
3. If the CT detects that the current of solar power generation drops under 6A, the charger
will keep charging at the minimum charging current 6A to avoid car dormancy. The
deficiency will be provided by the power grid.
4. Under ECO mode (selected with a tick), if turned ON, charging will start when the vehicle
is connected to the charger. If turned OFF, charging will not start until the ENABLE
button on the home is tapped.
NOTES:
x
Under Plug and Charge or Schedule Mode, if the CT detects the current from solar power
generation, the solar power output will work as a supplement. The charger will perform the
charging under the max set current by using a combination of power from the grid and
power from the solar system.
x
CT connections used with a solar system are only possible with single-phase models of
the charger. Three-phase models already use all the available connections.
x
ECO mode does not have load balancing functionality.
