8.7.4.5 Power AC
Activation and deactivation of the AC-Flex load contact in function of the active power of a
selected AC terminal. The parameters to setup this function are:
Selection of the active power in the system used for AC-
Flex load relay control:
• AcSource All
• AcSource L1
• AcSource L2
• AcSource L3
• AcFlex Source All
• AcFlex Source L1
• AcFlex Source L2
• AcFlex Source L3
• AcFlex Load All
• AcFlex Load L1
• AcFlex Load L2
• AcFlex Load L3
• AcLoad All
• AcLoad L1
• AcLoad L2
• AcLoad L3
Activation threshold Power [W]
If the measured active power exceeds this value, the
relay is activated.
Deactivation threshold Power [W]
If the measured active power exceeds this value, the
relay is deactivated.
The 2 threshold values are the boundaries of a hysteresis function.
8.7.4.6 Solar excess on-grid
Activation and deactivation of the AC-Flex load contact in function of the injected power into the
grid. The Solar excess on-grid pre-set is typically used for self-consumption. To limit the feed power
into the grid, loads are activated using AC-Flex load relays. The parameters to setup this function are:
Activation threshold Power [W]
If the measured total active power injected into the
source exceeds this value, the relay is activated.
Deactivation threshold Power [W]
If the measured total active power injected into the
source exceeds this value, the relay is deactivated.
These 2 values are the boundaries of a hysteresis function.
8.7.4.7 Solar excess off-grid
Activation and deactivation of the AC-Flex load contact in function of the load power and the
battery state of charge. The Solar excess off-grid pre-set is typically used to add loads when the
battery is fully charged (floating) and the inverter is working off-grid. The parameters to setup this
function are:
Activation threshold Power [W]
If the measured total active power load exceeds this
value, the relay is activated.
Deactivation threshold Power [W]
If the measured total active power load exceeds this
value, the relay is deactivated.
These 2 values are the boundaries of a hysteresis function.
