Battery
Integrator
Charging
multiple battery banks without use of diode isolators dictates that the
batteries be connected or “integrated” only whenever a charge voltage
is present so that they may be charged simultaneously, then
disconnected or “isolated” when in use to allow for selective discharge
and avoid having the secondary or standby battery drain into the
primary battery.
Battery Integrators perform
this function automatically, acting as a “smart” switch to connect
independent battery banks
only when a charging voltage is present. Otherwise, they are isolated,
and discharge between banks is prevented.
The traditional rugged and reliable diode isolator can also be used for
this function (see Battery Isolators above), as it also maintains
isolation between banks and allows charging from multiple sources.
However, one drawback is inefficiency when voltage is lost as current
passes through the diodes, resulting in undercharge if the charging
source does not compensate for the voltage drop.
The Battery Integrator causes no voltage drop in the charging system,
while the multiple batteries are charged as a single bank whenever a
charging source of approximately 13.2 VDC or 26.4 VDC or greater is
present (depending on model).
When the alternator or charger is off or a large load causes the
voltage to drop below the disconnect point the unit breaks the common
tie between the banks. This allows selective battery discharge and
prevents “dumping” of a higher-charged bank into a lower-charged bank.
The unit may also be activated to connect other batteries through the
key starter or a manual switch to provide an added “boost” from the
secondary battery whenever the starter is engaged and the unit senses
there is sufficient voltage in that battery to provide an assist.
For systems with more than two banks, an isolator must be installed for
each additional bank to provide the same isolation and integration as
described above.
Features
• Enables charging of two separate banks
without voltage drop, yet maintains 100%
isolation at all other times. For systems of three banks or
more, an additional unit must
be installed for each additional bank
• Heavy duty silver-plated contactor, continuous duty rated
• Voltage sense circuit, epoxy encapsulated
•12 volt, 100 amp model has ignition protection rating
• Easy three-wire hook up for two bank systems (BATT +, BATT +, GROUND)
• Terminal for optional wiring of remote light indicating when battery
banks are integrated
• Optional internal connection can be wired though key starter or
manual over ride switch,
tying battery banks together for extra boost during engine start

The Battery Integrator is ideal for
expanding the single charging output of an inverter-charger
to maintain both the house bank and an engine start bank, then to
isolate them during inverter function, so current is drawn from the
house bank only.
