7.2.2 Operating Mode
7.2.2.1 Operating Mode of WIT 29.9-50K-XHU
Priority of power supplied to the loads:
2. Batteries;
1. Solar panels;
Load First:
In Load First mode, the WIT inverter prioritizes supplying the solar power and
battery energy to the loads. If Export Limitation is disabled, the surplus solar
power can be fed to the grid, but the battery energy will not be exported to the
grid; if Export Limitation is enabled, neither solar power nor battery energy would
be sent to the grid.
3. Grid.
NOTE: In Load First mode, a meter is required.
Battery First:
In Battery First mode, the solar power is prioritized towards charging the battery
until the battery SOC (state of charge) reaches the preset upper threshold. Then it
will supply power to the loads. The further excess solar power, if any, can be fed to
the grid (Export Limitation disabled). In case that the solar power is insufficient,
the WIT inverter will draw power from the grid to charge the battery or supply the
loads.
Priority of power directed to charge the battery:
1. Solar panels;
3. Grid.
In Grid First mode, the WIT inverter prioritizes supplying the solar power to the
loads, exports the excess solar power to the grid, and sends the further surplus
power to charge the power. If the solar power is insufficient to support the loads,
the battery will discharge to supply power to the loads and the surplus battery
power will be sent to the grid for revenue.
2. Batteries;
Grid First:
Priority of power supplied to the loads:
1. Solar panels;
Zero export to meter:
2. Grid.
With Export Limitation enabled, no solar power or battery energy will be fed to the
grid in this mode. The inverter output is only supplied to the loads connected
before the external meter connection point. A meter is required. For the meter
wiring mode, please refer to Fig 6.6 in Chapter 6. The external meter will detect
power flowing to the grid and regulate the generated power so that only so much
energy is generated as is currently consumed by the primary loads, secondary
loads and charging the battery.

In this mode, there is no output at the inverter's GRID port. The solar and battery
power can only by supplied to Primary Loads via the LOAD port. The meter is not
required.

Smart Load:
Smart loads are connected to the GEN port and the Smart Load mode is set: during
on-grid operation, it will supply grid power to smart loads; during off-grid
operations, the power supply to smart loads is cut off. The wiring method is shown
in Chapter 6 Fig 6.4.
AC couple：
The grid-tied inverter is connected to the GEN port and the AC Couple mode is set:
during on-grid operation, the grid-tied inverter will be connected to the grid and
generate electricity via the GEN port; during off-grid operation, the grid-tied
inverter remains connected to the WIT inverter and generating power. The wiring
method is shown in Chapter 6 Fig 6.5.
