Concerning the detailed figure above:
1. Tick this box to do not export power back to the grid (the CT coil will detect power
flowing back to the grid and will reduce the power of the inverter only to supply the
local load).
2. Tick this box if you wish to export your solar power back to the grid.
3. Tick this box if you only want to supply power to the load side of the inverter.
4. ‘Zero Export Power’ is the amount of power flowing from the Grid to the Inverter. Set
this value to ’20 - 100W’ to instruct the inverter to always take the prescribed amount
of power from the Grid to minimise the tripping of sensitive pre-paid electricity meters
if ‘Reverse Power Detection’ occurs.
5. This controls the maximum overall power, both to the ‘Load’ and ‘Grid’ ports
combined. It is set to Low if an ‘over-current’ fault occurs
6. Tick this box if you wish to set the solar panels give power to the ‘Load’. If you un-
tick this box the solar will send power to charge the batteries.
Example:
This example shows the battery being charged up to 100% by both the Grid and Solar
PV from 8 a.m. to 11 a.m. and then being able to supply up to 4kW of battery-power to
the ‘essential’ loads from the ‘Load’ Port until the battery SOC drops to 50%.
IMPORTANT - When charging the batteries from the Grid or Generator, please ensure
you have set the correct correct battery-charging settings on the battery charge as
shown in Section 4.10 ‘Battery Setup’ Home Page. If the ‘Use Timer’ function is
activated then the inverter will use the battery power according to your settings when
the Grid is present. If this function is not set, the batteries WILL ONLY be used for
backup when there is no utility grid power.
Example:
This is a zero-export power to the grid example.
The power produced is supplying the ‘Non-Essential Load’ while the inverter is set at
a maximum power of 8kW (Max Sell Power). The inverter is connected to the grid, but
