NOTE:
Before connecting the battery, measure the open-circuit
voltage. It must be over 10 volts to start the controller. If the
system voltage Settings Switches are set to Auto-detect, battery
voltage over 15.5V will be detected as a 24V nominal battery,
and the unit will charge accordingly. The 12/24V auto selection is
only done at start-up, and the detected system voltage will never
change during operation.
Generally, the specfic system voltage is known, and it is best
to set DIPs 2,3 accordingly; the auto-detect setting should
be used only in rare circumstances.
Switches 4, 5, 6: Battery Type Selection
Preset ProStar MPPT battery charging options are shown in
table 3-1 below. All voltage settings listed are for nominal
12 volt batteries.
Multiply the voltage settings by two (2) for 24 volt systems.
NOTE:
These settings are general guidelines for
use at the operator’s discretion. The ProStar MPPT
can be programmed to satisfy a wide range of charging param-
eters, but only the battery manufacturer can recommend optimal
settings for their products.
