Section 4 - Samlexpower Evolution EVO-2212 Owner's Manual

SECTIOn 3 |
When the second auxiliary deep cycle battery is used, a battery Isolator is required that will al-
low parallel connection of the two batteries for charging when the alternator is ON and discon-
necting the parallel connection when the alternator is stopped (Isolator is shown in figs. 3.14a
and 3.14b). The capacity of the battery Isolator should be as follows:
• for evo-2012: The maximum continuous DC current required is 266A. The capacity of
the battery Isolator should be more than 266A or more than the capacity of the alternator,
whichever is higher
• for evo-2224: The maximum continuous DC current required is 133A. The capacity of
the battery Isolator should be more than 133A or more than the capacity of the alternator,
whichever is higher
• for evo-3012: The maximum continuous DC current required is 373A. The capacity of
the battery Isolator should be more than 373A or more than the capacity of the alternator,
whichever is higher
• for evo-4024: The maximum continuous DC current required is 266A. The capacity of
the battery Isolator should be more than 266A or more than the capacity of the alternator,
whichever is higher
3.16.3 requirement to Keep the neutral conductor of Shore Power isolated
from the chassis ground of the rv
As explained in on-line white Paper titled "grounded electrical Power Distribution
System", in the rV, the Neutral bus bar is NOT bonded to the Chassis of the rV. In the rV,
the Neutral is floating with respect to the chassis of the rV. This is necessary for safety
because if the Neutral was bonded to the chassis of the rV and if the Neutral and the hot got
reversed by mistake, the chassis of the rV will be at 120 VAC with respect to the Earth
Ground. If a person standing on the Earth Ground touches the chassis of the rV, he will be
fed with 120 VAC and will receive electrical shock!
3.16.4 typical mobile installation
fig 3.14A illustrates typical rV installation using 30A, 120VAC, Single Phase Service Inlet and
fig 3.14b illustrates typical rV installation using 50A, 120/240VAC Split Phase Service Inlet:
Auxiliary battery is connected to the DC input connections through an appropriate fuse
–
to protect the DC input cables against short circuit
Auxiliary battery will be charged by the alternator through the battery Isolator
–
battery Temperature Sensor Model bTS-EVO is installed on the Positive or Negative post
–
of the auxiliary battery and connected to the port for the Temperature Sensor
Supplementary battery charging is being carried out through a solar array and a
–
Charge Controller connected to the DC input provided for external battery charger
AC input to the EVO is fed from the Electrical Panel of the rV (through suitable
–
breaker) and from the generator (through suitable breaker).
If the rV has a 50A Service, 120VAC Single Phase input to the EVO can be fed from
–
either of the 2 Split Phase Legs of the 50A rV Panel (through suitable breaker).
AC output from the EVO is fed to the Electrical Sub-Panel for EVO (use 120V version
–
and NOT 120/240 Split Phase version of the Electrical Sub-panel)
Automatic Generator start/stop is possible. Please see Section 4.7 for details.
