4.3 Operating Mode Introduction
4.3.1 On Grid Self-Use Operating Mode
The on grid self-use operating mode is recommended for the
system installed in area with a stable grid. The purpose is to
increase self-consumption of the clean PV energy. When Inverter
is set to work in this mode:
i. During daytime and there is sufficient PV Power,
• The PV energy is used to supply local loads with first priority
and then charge the battery, excessive energy will be fed
into grid*1*2.
• When battery is fully charged, PV energy is supplied to the
local loads and fed into grid*1*2.
ii. During nighttime or there is not sufficient PV Power,
• Battery is discharged to supply local loads, if extra power is
required, it will be imported from grid.
• When the battery SOC is below the setting value or fully
discharged, the inverter will stop working and local loads will
