Allow to charge battery: This option is automatically determined
by setting in “Charging source”. It’s not allowed to modify here.
When “NONE” is selected in charging source section, this option
becomes unchecked as grey text.
Allow AC to charge battery: This option is an automatically
determined by setting in ”Charging source” and cannot be
modified here. When “Grid and PV” or “Grid or PV” is selected in
charging source section, this option is default selected. Under
Grid-tie mode, this option is invalid.
Allow to feed-in to the Grid: This option is only valid under
Grid-tie and Grid-tie with backup modes. Users can decide if this
inverter can feed-in to the grid.
Allow battery to discharge when PV is available: This option is
automatically determined by setting in “Load supply source (PV
is available)”. When “Battery” is higher priority than “Grid” in
Load supply source (PV is available), this option is default
selected. Under Grid-tie, this option is invalid.
Allow battery to discharge when PV is unavailable: This option is
automatically determined by setting in “Load supply source (PV
is unavailable)”. When “Battery” is higher priority than “Grid” in
Load supply source (PV is unavailable), this option is default
selected. Under Grid-tie mode, this option is invalid.
Allow battery to feed-in to the Grid when PV is available: This
option is only valid in Grid-tie with backup II or Grid-tie with
backup III modes.
Allow battery to feed-in to the Grid when PV is unavailable: This
option is only valid in all options of Grid-tie with backup mode.
PV energy supply priority setting:
1 Battery, 2 Load and 3 Grid.
PV power will charge battery first, then provide power to the
load. If there is any remaining power left, it will feed-in to the
grid.
Battery charging source:
1. PV and Grid (Default)
It is allowed to charge the battery from PV power first. If it’s
not sufficient, grid will charge battery.
2. PV only
Only PV power will be used to charge battery.
3. None
The battery will not be charged by this inverter.
Load supply source:
When PV power is available:
1 PV, 2 Grid, 3 Battery
If battery is not fully charged, PV power will charge battery first.
Remaining PV power will provide power to the load. If it’s not
sufficient, grid will provide power to the load. If grid is not
available at the same time, battery power will back up.
When PV power is not available:
1. 1 Grid, 2 Battery (Default)
Grid will provide power to the load at first. If grid is not
available, battery power will provide power backup.
2. 1 Battery, 2 Grid
Battery power will provide power to the load at first. If
battery power is running out, grid will back up the load.
NOTE: This option will become ineffective during AC charging
time and the priority will automatically become 1 Grid and 2
Battery order. Otherwise, it will cause battery damage.
