Remote Shutdown
Naturally, when you are not using the inverter•charger,
you will disable the inverter to conserve your battery. The inverter•charger
still draws up to 50mA of battery current, however—and this will eventually
discharge the battery. So when you don’t need the inverter•charger for an
extended period of time, you can reduce battery draw to less than 1mA by
setting the inverter•charger’s ON/OFF/REM switch to OFF.
This disables all circuitry in the inverter•charger and removes all power from
the display panel. Setting the inverter•charger’s ON/OFF/REM to REMOTE
lets you achieve the same result using a conveniently located system “kill”
switch. This feature is particularly valuable for vehicles like ambulances
where it is imperative that the system not draw power when the vehicle motor
is not running.
Charging
Built-in Charge Formulas
For the inverter to perform at the highest level,
the batteries must be charged correctly. Every battery has a unique charge
formula (or “algorithm”) dictated by the manufacturer for optimal
performance. The PROsine 2.0 has
twenty-one built-in formulas
to charge
your batteries correctly—and you have the ability to fine tune these formulas
to meet the needs of new models or specialized batteries.
Battery Temperature Sensor
Since battery temperature is a key factor in
correct charging, the charging formula must be adjusted (automatically and in
real time) according to the actual battery temperature to ensure that batteries
are fully, but not over charged. For this reason, Xantrex has included a battery
temperature sensor with your PROsine 2.0 Inverter•Charger and has
temperature compensated the charge algorithm.
Manual Equalization Mode
Over a period of time, the cells in a flooded
battery can develop uneven chemical states. This can result in a weak
(undercharged) cell which, in turn, can reduce the overall capacity of the
battery. To improve the life and performance of a non-sealed flooded battery,
the PROsine 2.0’s multi-stage charging cycle includes a manual Equalize
mode that should be used occasionally to restore an equal chemical state to all
cells.
Dead Battery Charging
In addition to the numerous features which let you
maximize your battery’s life and performance, the PROsine 2.0—unlike many
chargers—also has the ability to recharge batteries even if the voltage is near
zero.
