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” at www.samlexamerica.com (Home > Support > White Papers)
, 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. 3.14 illustrates a typical RV installation using 30A Service Inlet for 30A RV Power Supply
Cord:
•
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 typical 30A RV Power Inet (through suitable breaker)
and from the generator (through suitable breaker)
•
AC output from the EVO is fed to the RV Distribution Panel Board (Use 120V version
and NOT 120/240 Split Phase version)
•
Automatic Generator start/stop is possible as follows:
o
Start operation is initiated by contact closure of the Status Relay (14, Fig 2.1)
when battery voltage drops to the programmed value of the Low Voltage Alarm.
Stop sequence is initiated by contact opening when the battery voltage rises to
the programmed “Restart Value”.
o
Contact closure/opening signal is fed to the optional Generator Auto Start/Stop
Module which in turn feeds required start stop signals to the generator (the gen-
erator should be capable of remote start/stop function).
