ELECTRICAL SYSTEM
MASTERVOLT INVERTER/CHARGER
Mastervolt PN 37014005 12/4000-200A
Mass Combi Inverter Charger is fully
automatic. Under normal circumstances
there is no need for adjustment or operation
besides switching on and off.
The Mass Inverter Charger Control
(MICC), shown at right in the “Charge”
mode, is a digital remote panel switches on
and off the Mass Combi unit but is a battery
consumption meter. The information provided includes: reading voltage, current, consumed Ah,
time remaining and remaining capacity as a percent of max available battery capacity. An
integrated alarm system is included. (See Mastervolt Operators Manual)
The 40z uses a combination inverter/charger (in a single unit). When AC power is sourced
from Shorepower or the Generator the unit can charge both the house battery bank and the
engine start batteries. The “charger/inverter” breaker (on the AC Shore 1) should be ON. On the
MICC Panel, turn “Charge” ON and “Invert” OFF. Reverse the process when Inverting.
INVERTING To use AC power when no generator or shore-power is available, make sure
the charger/inverter breaker on AC Shore 1 is ON. Push CHARGE on the MICC remote panel
until the readout shows OFF. The push INVERTER until the readout shows ON” on the MICC
remote panel. AC power should now be supplied to the forward AC Shore 1, which includes
those items which may be run from the inverter alone$although not necessarily
all at the same time for very long. The inverter can only receive 12v current from the house bank,
but can monitor both the house and engine start banks.
ERROR 6 If you sequence pushing of the buttons wrong, you can sometimes get an “Error 6”
message. No problem. Reach into the Starboard Pilothouse Settee locker on top of the Inverter
and with two fingers, rocker the “Main Switch” forward to OFF than aft again to ON to reset.
