If the Smart Energy Meter is abnormal or not equipped, the inverter will run normally, how-
ever, the battery can be charged but not allowed to discharge. In this case the feed-in power
setting will be ineffective, and the DO function for optimized mode will be disabled.
Energy Management during Daytime
The energy management system (EMS) works in self-consumption mode by default.
• Scenario 1: PV power generation ≥ Load power consumption
– First，PV power will go to Backup loads first, then normal loads and the battery.
– Moreover，If the battery is fully charged, the excess will go to the grid. The feed-in
power will not surpass the feed-in limitation value in initial settings.
• Scenario 2: PV power generation ＜ Load power consumption
– First，battery will discharge and provide the energy missing.
– Moreover，inverter will draw power from the mains if the power from the PV and bat-
tery is less than the load power.
With current No current
Energy Management during Night
During night, with energy available, the battery will discharge to supply power for loads. Al-
ternatively, the grid will supply power for the loads in case the discharge power of the battery
is insufficient.
