IVR-2400MPPT model default setting: 27.0V
If self-defined is selected in program 02, this program can be set up. Setting
range is from 13.0V to 14.6V for
IVR-1200MPPT
model and increment of each
click is 0.1V. Setting range is from 26.0V to 29.2V for
IVR-2400MPPT
model and
increment of each click is 0.2V.

power source
priority
Utility first (default)
Utility will provide power to the loads as first priority.
Solar and battery energy will provide power to the
loads only when utility power is not available.
Solar first
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 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 low-level warning voltage or
the setting point in program 10.
SBU priority
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 10.
