6.4 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 a supply of AC power is
present (from AC Shore 1 or generator), the unit can charge both the house battery bank and the
engine start battery. The “charger/inverter” breaker (on the AC Shore 1) should normally be ON. If
no source of AC power is available, the inverter can use DC power from the house bank to create
AC power, used for items on AC Shore 1. If AC power becomes available, either from shore-
power or the generator, the Mass Combi transfers this power to AC Shore 1. In other words, your
batteries will not be used to create AC power if either the generator or shore-power #1 is active
and the inverter breaker is ON.
Inverting –
When not using generator or shore power, this switch may remain off. It does not
control the inverter. Its only function is to turn the charger on when shore power or the generator
is in use. It probably makes sense to change the breaker panel label to read CHARGER.
Push INVERTER so the readout shows “Inverter 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. When finished using AC power through the inverter push INVERTER again to so the
readout indicates “Inverter OFF”.
Charging
– When using SHORE POWER or the GENERATOR, switch the
CHARGER/INVERTER breaker on the AC Shore 1 panel to ON. Push CHARGER on the MICC
panel to activate the charger. The MICC panel will display CHARGER ON. Push CHARGER on
the MICC panel again before disconnecting the shore power or turning off the generator. This
will display CHARGER OFF on the MICC panel.
ERROR 06
If you forget to do this, the next time you either connect to shore power or turn on
the generator, the current surge will trip the switch on the charger and display
ERROR 06
on the
MICC panel. To correct this, open the starboard bridge deck settee hatch and push the rocker
switch on top of the inverter/charger unit aft to the ON position. This will allow shore power or
generator power to go the charger and other 120 volt circuits.”
