4. Operating Modes
This system is composed of six modes : PV Auto, PV Only, Battery discharge, Standby,
Maintenance (forced charge), and Stand-alone. The event check status should not be
considered as any specific mode.
4.1 Standby Mode
This is the standby mode before converting to operation mode (PV Auto, PV Only, Battery
discharge mode). Conversion to the operation mode (PV Auto, PV Only, Battery discharge
mode) is made by the EMS decision.
4.2 PV-Auto Mode
This mode is divided into three types depending on the state of the Battery power.
4.2.1 Weak
Solar energy generation and Battery discharging are available. The solar-generated power
is charged or discharged to the Battery based on the EMS decision. A maximum of 4.6kW
or more can be sent to Grid. When Load Output Power (Sub) is higher than power generation
of PV and Battery, Grid power supplied to the Sub.
