3. When the user set it as “ allow feed-in but limit the feed-in power” , as shown in Figure 3-F,
the excessive solar power will first charge the battery. The charging current will be adjusted
according to the current feed-in power until the feed-in power of the utility grid is less than the
ntil the feed-in power of e 0.5kW is used for the explanation) set by the user. When the battery
is fully charged or the charging current has reached its top limit, the inverter will limit the output
power.
After 17:00pm, the solar power generation power is less than the load requirement; therefore
ESS-MET measured that it is currently purchasing electricity and confirms that the battery capacity
is sufficient. So it will discharge to supply load power until after 21:00pm when the battery power is
depleted and the power required by the load afterwards are all provided by the utility grid.
When the time reaches 22:00pm, ESS will automatically activate to charge the battery.
