3.4.2 Battery mode
INPUT
Solar
Only solar energy can charge the battery, no matter utility is
available or not.
Solar Priority
When PV power is sufficient, PV charges the battery. When the
battery voltage is lower than AON, the utility charges the battery
as a supplement; when the battery voltage is higher than AOF,
the utility stops charging the battery.
Note: AOF and AON setting refers to Item 17/18 on the
Advanced interface for engineers.
Utility & Solar
PV and utility charge the battery at the same time. When PV
power is sufficient, the PV power is the primary source.
Note: After selecting this working mode, the output mode is
not controlled freely, though it can be set. Details refer to the
below instructions.
OUTPUT
Inverter Priority
PV power is sufficient (namely, extra energy exists except
charging the battery), PV supplies the load as a priority. When
PV power is insufficient, the battery supplies the load as a
supplement. When the battery voltage is lower than LVD, the
utility supplies the load as a supplement.
Note: LVD and LVR settings refer to Item 7 on the Standard
interface for common users.
Utility Priority
Utility supplies the load as a priority.
When the utility is abnormal, the PV supplies the load as a
supplement. When PV power is insufficient, the battery supplies
the load as a supplement.
