Solar energy provides power to the
loads as first priority, If solar energy is
not sufficient to power all connected
loads, Utility energy will supply power
to the loads at the same time. The
battery energy will supply power to the
load only in the condition of the utility is
unavailable. If the solar is unavailable,
the utility will charge the battery until
the battery voltage reaches the setting
point in program 21.If the solar is
available, but the voltage is lower than
the setting point in program 20, the
utility will charge the battery until the
battery voltage reaches the setting
point in program 20 to protect the
battery from damage.
Solar energy provides power to the
loads as first priority, If solar energy is
not sufficient to power all connected
loads, battery energy will supply power
to the loads at the same time. Utility
provides power to the loads only when
battery voltage drops to either low-level
warning voltage or the setting point in
program 20 or solar and battery is not
sufficient. The battery energy will supply
power to the load in the condition of the
utility is unavailable or the battery
voltage is higher than the setting point
in program 21(when BLU is selected) or
program 20(when LBU is selected). If
the solar is available, but the voltage is
lower than the setting point in program
20, the utility will charge the battery
until the battery voltage reaches the
setting point in program 20 to protect
the battery from damage.
