3. Operating Modes

This system is composed of six modes : PV Auto, PV Only, Battery discharge, Standby,
Maintenance (forced charge), and Stand-Alone (Back-up). The event check status should
not be considered as any specific mode.

3.1 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.

3.2 Event Check Mode

This mode stops solar energy generation and put it in standby mode as an event occurs.

3.3 PV-Auto Mode

This mode is divided into three types depending on the state of the Battery power.

3.3.1 Weak

Solar energy generation and Battery discharging are available. The solar-generated power
is supplied to sub and load. In case of insufficient power, the battery is discharged on
the EMS decision. When Load Output Power (Sub) is higher than power generation of PV
and Battery, Grid power supplied to the Sub.
• Use smart meter. The energy supply priority is : load (sub+main) > grid
• Not use smart meter. The energy supply priority is : sub_load > grid
