Solar first
(default): Solar energy provide
power to the loads as first priority.
If solar energy is not sufficient to power all
connected loads, battery energy will supply
power the load at the same time.
Utility provides power to the loads only
when any below condition happens:
-Solar energy is not available
-Battery voltage drop to either low-level
warning voltage or the setting point in
program 5.
Utility first
: Utility will provide power to the
loads as first priority.
Solar and battery energy will provide power
to the load only when utility power is not
available.
SbU
: Solar energy provide power to the
loads as first priority.
If solar energy is not sufficient to power all
connected loads, battery energy will supply
power the load at the same time.
Utility provides power to the loads only
when battery voltage drop to either low-
level warning voltage or the setting point in
