Setup
Settings for MSH4024RE:
Info:
The MSH4024RE is a dual input source inverter/charger having two independent
AC source inputs (AC1/GRID and AC2/GEN) with independent
VAC Dropout
settings for
each input. The
Set VAC Dropout
menu only displays both the
AC1
and
AC2
fi
elds if the
remote is connected to a MSH4024RE model.
◊
Set VAC Dropout
(AC1 and AC2) – The
AC1
setting determines at what AC voltage—from
the AC1 to NEUT terminals—the inverter/charger will connect to or disengage from the incom-
ing AC. The
AC2
setting determines at what AC voltage—from the AC2 to NEUT terminals—the
inverter/charger will connect to or disengage from the incoming AC.
Default setting:
AC1=80 VAC
,
AC2=70 VAC
Range:
60-100 VAC, UPS Mode
(AC1 only)
Where do I set my VAC Dropout?
It depends on the application and what you are using as the
AC source. The settings not only look at the incoming voltage level to determine when to transfer,
but also determine how quickly the charger disconnects and starts inverting based on the
fl
uctua-
tions of the incoming AC voltage.
Dropout = 60 VAC to 100VAC (Export inverter models: Dropout = 110 VAC to 190 VAC)
– Use a
VAC Dropout
setting from 60-100 VAC (export models use from 110-190 VAC) when the
AC source may have
fl
uctuations in RMS voltage. These settings attempt to prevent the charger
from disengaging unnecessarily due to poor quality voltage, and are highly recommended if using
a generator for charging. The transfer time from Standby mode to Inverter mode is >16 millisec-
onds when using these settings.
Dropout = UPS Mode
– Use the
UPS Mode
setting when the AC source is well regulated above
105 VAC (200 VAC for export models), and the inverter loads are sensitive to voltage
fl
uctua-
tions. This setting is intolerant of voltage
fl
uctuations and will provide a quick transfer. The trans-
fer time from Standby mode to Inverter mode is
≤
16 milliseconds when using this setting.
Note:
Do not use this setting if using a generator as your AC source.
Info:
If you get nuisance AC disconnects, either change the setting to 100 VAC or less
(export models 190 VAC or less), or obtain a better voltage-regulated AC source.
• 03C Battery Type
– This setting selects the battery type, which determines the battery
charge pro
fi
le and ensures the batteries are receiving the proper charge voltage. The charge
voltage settings are
fi
xed when using the
GEL
,
Flooded
,
AGM1
, or
AGM2
selections, but can
be adjusted if using the
CC/CV
or
Custom
selections.
Default setting:
Flooded
Range:
AGM1, AGM2, Flooded, GEL, CC/CV, Custom
◊
Set Battery Type (GEL, Flooded, AGM1, or AGM2)
– When the battery type selection
is
GEL
(for Gel batteries),
Flooded
(for liquid lead acid batteries),
AGM1
(for Lifeline AGM
batteries), or
AGM2
(for East Penn/Deka/Discover/Trojan AGM batteries), the charge voltage
level for the Absorption, Float, and EQ charge modes are
fi
xed and shown in Table 3-1—de-
pending on the battery type selected and the nominal inverter battery voltage.
Info:
The voltage settings shown in Table 3-1 are based on the Battery Temperature
Sensor (BTS) at a temperature of 77°F (25°C), or not connected. If the BTS is connected,
the actual charge voltage will increase if the temperature around the BTS is below 77°F
(25°C), and decrease if higher than 77°F (25°C). This ensures the batteries receive the
correct charge voltage regardless of temperature.
