Info: If you are supplying two AC sources (utility and generator) to the inverter’s single
input through an AC transfer switch, adjust the AC Input Amps setting to the smaller AC
circuit breaker side of the two AC sources.
Info: The AC Input Amps setting is dependent on the stability of the AC source. If
using a generator, factors such as altitude and output voltage regulation may require
a lower setting than the generator’s circuit breaker size. For best performance, lower
the AC Input Amps setting to 1/3 of the generator’s rated capacity, and then while
the generator is heavily loaded, gradually increase the setting as high as possible; but
ensure the voltage level stays above the 03B Low VAC Dropout setting.
• 03B Low VAC Dropout: Selects the minimum AC voltage that must be present on the input
before the inverter/charger connects to the AC input and switches from Inverter mode to
Standby mode. This setting also determines the lowest AC voltage that is allowed before the
charger disengages and the inverter (if enabled) resumes powering the AC loads from the
inverter’s battery power—to protect AC loads during utility outages.
Example: If the Low VAC Dropout setting is 60 VAC, then the AC input voltage must be above 60
volts before the inverter connects and switches from Inverter mode to Standby mode. Once the
AC is connected, the AC voltage must drop below 60 VAC to switch back to Inverter mode.
Settings for all models except MSH4024RE:
◊ Set Low VAC Dropout (AC1 only) – Sets at what AC voltage—from the HOT IN 1 to NEUT
IN 1 terminals—the inverter/charger connects to or disengages from the incoming AC.
Default setting: 80 VAC ( 150 VAC for export models)
Range: 60-100 VAC, UPS Mode ( 110-190 VAC, UPS Mode for export models)
Settings for MSH4024RE models:
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 Low VAC Dropout screen only displays both the AC1 and AC2 fi elds
if the router is connected to the MSH4024RE.
◊ Set Low VAC Dropout (AC1 and AC2) – The AC1 setting determines at what AC
voltage—from the AC1 to NEUT terminals—the inverter/charger connects to or disengages
from the incoming AC. The AC2 setting determines at what AC voltage—from the AC2 to NEUT
terminals—the inverter/charger connects to or disengages from the incoming AC.
Default setting: AC1=80 VAC, AC2=70 VAC
Range: 60-100 VAC, UPS Mode*
* – Do not use UPS Mode as the AC2 setting if using a generator as your AC source.
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 of
the fl uctuations of the incoming AC voltage.
Dropout = 60 VAC to 100VAC (Export inverter models: Dropout = 110 VAC to 190 VAC)
– Use a Low VAC Dropout setting from 60 VAC to 100 VAC (export models use a dropout from
110 VAC to 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 milliseconds 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 inverter models), and the inverter loads are sensitive to voltage
fl uctuations. This setting is intolerant of voltage fl uctuations and provides a quick transfer. The
transfer time from Standby mode to Inverter mode is ≤ 16 milliseconds when using this setting.
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.
