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