5.3、AC output mode
The AC output mode corresponds to the parameter operating priority mode and the utility hybrid with load
function setting item, allowing the user to set manually.
• Utility Priority Output 01 UTI (default)
Utility priority, switching to inverter only when utility is outaged (Priority: Utility > PV > Battery)
• Solar and Utility Hybrid Output 34 MIX LOD
In UTI mode and parameter [34]=MIX LOD, when not connected to the battery or when the battery is full,
the solar and the utility supply power to the load at the same time. (Priority: PV > Utility > Battery)
• Solar Priority Output 01 SOL
The PV gives priority to powering the load, and when the PV meets the load, the excess power charges
the battery.
When the PV energy is insufficient, the battery replenishes to power the load.
When the PV is ineffective, switches to mains power, and then finally to use battery power.
When the PV energy is insufficient, as well as when the battery falls below the parameter (battery to
mains) or switching to the mains SOC setting value, switches to mains power supply to the load and
charging, where the PV's energy is charged, without load. This mode maximises the use of the PV while
maintaining battery power and is suitable for areas with stable grids.(Priority: PV > Utility > Battery)
