The items listed above are for reference only. In order to compute the actual wattage of
a device, determine the Amps the device is rated at and then Multiply the Amps x Volts = Watts.
For example: 10A x 120V = 1200 Watts
Or select the number of devices listed above you intend to use and add the Wattage of each
device to give you an estimated total. Select a model that is equal or greater than the total.
These load ratings are for guidance only, check your specific needs and compare
to the maximum rating on your new TruePower Combi unit.
DC POWER DRAW – Remember: The inverter consumes DC battery power to supply the AC
loads; it is not recommended that large appliances such as electric stoves and water-heaters
be run via the TruePower Combi inverter. The TruePower does include low battery protection
to prevent complete discharge of your DC system. It is extremely difficult to predict how
long the attached DC battery bank (no matter what size or type) will sustain the use of the
inverter connected loads. This must be done on a trial and error basis. ProMariner
recommends that once a comfortable load is established, that notes are added to
the end of this manual for future reference. This load vs. time ratio will change as
batteries age or are replaced.
START UP CURRENT (INRUSH) - Many motor operated appliances have a higher
wattage requirement to get started than while running. This is called “inrush”
current. Your TruePower Combi unit is capable of running 2.8 times its rated current
for this reason. If an appliance requires more than the rating of the TruePower
Combi, or within the rating for a longer duration than 10 seconds the unit will shut
down. Resetting the unit is achieved by turning the 3 position rocker switch to the
Off position. The unit will then self-check and clear the fault. The appliance should
be tried multiple times before determining that its draw is too large for the TruePower
Combi unit to handle, no damage will result with multiple attempts. See the
Troubleshooting section of this manual for more detailed fault information.
MULTIPLE APPLIANCES – Similar to the inrush current discussed above, care should be
taken to stagger the start-up of multiple loads. It is possible to exceed the overload of the
capacity upon start-up of multiple appliances even though, combined, their ratings do not
exceed the rating of the unit. Resetting the unit is achieved by selecting the Off position
on the 3 position rocker switch. The unit will then self-check and clear the fault. See the
Troubleshooting section of this manual for more detailed fault information.
RECHARGING BATTERIES – ProMariner recommends that batteries are recharged
before they are fully discharged. This practice will ensure the longest possible
lifespan of your batteries. It is recommended that a Remote Battery Status indicator
is used to monitor your battery bank.
Installation
NOTE: ProMariner highly recommends that this unit be installed by an ABYC
Certified Electrical Technician. Guidance from ABYC E-11 AC & DC Electrical
Systems on Board Boats and ABYC A-31 Battery Chargers & Inverters is offered
throughout this manual to ensure a safe, trouble free installation. Please re-read
the PERSONAL PRECAUTIONS section of this manual prior to installation.
LOCATION – This unit must be located in a dry, well ventilated area, free from
unsecured hardware. Temperature is also a serious consideration. Do not mount
this unit in areas where temperatures will exceed 40
° C (104° F). Generally this
includes engine compartments where operating temperatures are often exceeded
substantially by temperatures after shutdown when airflow is lessened due to the
lack of combustion air required.
LOCATION – This unit is NOT IGNITION PROTECTED, therefore it cannot be mounted
in a location containing:
1) Gasoline powered machinery (e.g. engine or generator), or
2) Gasoline fuel tank(s), or
3) Joint fitting(s) (e.g. fuel filters, valves) or,
