If setting “Utility” priority, utility will provide
power to loads as first priority. Solar and
battery energy will provide power to loads
only when utility power is not
available.(default)
If setting “SOL” priority, solar energy will
provide power to 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 any one condition happens:
-Solar energy is not available
-Battery voltage drops to the low-level
warning voltage or the setting voltage
point in program 006
If setting “SBU priority”, solar provides
power to the loads as first priority.
If solar energy is not sufficient to power all
connected loads, battery energy will
provide 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.
