Figure 3-13, Setup: 06 Vac Dropout Selections - Magnum Energy ME-RC Owner's Manual

• SETUP: 06 VAC Dropout – Used to select the minimum AC voltage that
must be present on the input before the inverter/charger switches from
Inverter to Standby mode. This setting also determines the minimum
AC voltage threshold where the charger disengages and the inverter
(when turned on) will provide AC power from the batteries. This protects
AC loads from utility outages.
Default setting: Dropout = 80 VAC (Export models = 150 VAC)
Range: US models: 60-100 VAC, UPS Mode; Export models: 110-190
VAC, UPS Mode
Example: If this setting is set to Dropout = 60 VAC, then the AC input
voltage must be above 60 volts before the inverter will switch from Inverter
mode to Standby mode.
Example: If this setting is set to Dropout = 60 VAC, when the AC input
voltage drops to 60 volts the inverter will switch from Standby mode to
Inverter mode.

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.
Note: If the ME-RC is connected to a MSH-RE inverter, the VAC Dropout
setting applies to both inputs (AC1 and AC2).
Dropout = 60 VAC to 100 VAC (export inverter models – Dropout
= 120 VAC to 200 VAC): Use a VAC dropout setting from 60 VAC to 100
VAC (export models—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 millisec-
onds when using these settings.
Dropout = UPSmode: 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 will provide a quick transfer. The
transfer time from Charge mode to Inverter mode is
when using this setting. 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 inverter models—190 VAC or less), or
obtain a better voltage-regulated AC source.
