3-2-3-2. Scheduling–Scheduling control function descriptions
Scheduling control allows time of use users to customize the charging/discharging time of the
ESS system to charge the battery usually at night or before dawn when the electricity price is lower.
During the periods when the electricity price is higher, if the solar power generating power is lower
than the required load power, discharge the battery for the load to use.
As shown in figures 3-D, 3-E, 3-F, between the hours of 12:00am and 6:00am, purchase electricity
with lower price to charge the battery and also purchase electricity for the load to use.
After 6:00am, ESS confirms that the battery power is sufficient, therefore it discharges for the load
to use. Between the hours of 9:00am~15:00pm, the solar power generation power is greater than
the load need, so now the excessive solar power will be processed according to the feed-in power
setting set by the user.
1. When the user set it as “
do not allow feed-in, as shown in Figure 3-D, the excessive solar
power will first charge the battery.The charging current will be adjusted according to the battery
capacity. When the battery is fully charged or that the charging power was not enough to
absorb all the solar power, the inverter will limit the output power until the feed-in power of the
utility grid is zero.
2. When the user set it as “ allow feed-in , as shown in Figure 3-E, the excessive solar power will
all be fed to the utility grid.
