Solar Configuration
7KW
For solar features to work, the CT clamp must be installed correctly and the following
settings must be set prior to switching Solar Modes:
- Enable Power Allocation Charge - Enabled
- External current sampling wiring method- CT2000
The charge point can work with grid-tied solar system, to detect and use the residual solar
power to charge your car that would. Otherwise be fed back to the grid. This can help
increase the self-usage rate of the solar system and reduce electricity bill for the
household.
The charge point supports 3 charging mode with grid-tied PV system: FAST, ECO and
ECO+
Introduction to the 3 modes for solar charge
FAST Mode: Charge at the rated power, the car can be fully charged in the shortest time at
this mode.
ECO Mode:
(1) The charge point uses only surplus solar power to charge car when the surplus solar
power is greater than 1.76kw (6 amps).
(2) When surplus solar power is lower than 1.76kw, the charge point will charge at 1.8kW
and use grid power to offset the shortage part.
ECO+ Mode:
(1) Dynamically adjust the charging power according to the available surplus power. If
there is no enough excess solar power(>1.8kW), the charging will stop until there is residual
solar power greater than 1.8kW again.
(2) It is allowable to set a value between 0-1.76kW. When the power import from grid
exceeds this preset threshold, charging will cease. When solar export exceeds this value,
the charging will resume.
