AC in source priority
Note:
ACin First: The system will work in AC input first
mode (default)
When there is an AC input, the load will firstly be
powered by the AC input. When the solar panel is
sufficient to charge the battery independently and
there are still some surplus solar power, it will also
supply power to the AC load together with the AC
input.
BATT First: The system will work in battery first
mode.
When the PV power is more than the power of the
AC load in operation, the solar energy will charge
the battery and supply power to the AC load first.
When the PV power is less than the power of the
AC load in operation and the solar panel is
insufficient to take the AC load, the battery will
discharge to supply power to the AC load together
with the solar panel
When the battery is running low (lead-acid battery
under low-voltage protection or lithium battery
under SoC protection) and both solar and battery
are insufficient to power the load, the AC load will
be powered by the grid only, and the battery will be
charged by the grid as well as the solar panel
until
the battery is charged at constant voltage and the
overload is removed, the system will disconnect the
grid power supply and restore to the battery first
mode.
Time Ctrl: Set the time period for the BATT First
mode, once it exceeds this time period, it will
automatically switch to the AC input to supply
power
