VI.Introduction of power management
and off-peak charging

6.1 Power management

The working principle of power management is as below,
Assume the max current can be supplied to the property is 40A, then the max power
is 40Ax230V = 9.2kW. So you can set the max power import to 9.2kW.
If CT is used to detect power import, then select CT as the power sampling device in
the parameter setting page. The charger will adjust charging power according to the
real-time power import and max power import.
When real-time import exceeds 90% of the preset max import value, the charger will
decrease charging power at a rate of 2A/sec until the real-time value drops between
80%-90% of the max value.
When real-time import drops below 80% of the max value, the charger will increase
charging power at 2A/sec until the real-time import falls between 80%-90% of the
max import value .
