gel, have charging requirements up to 14.4V (12V battery).
Depending on the battery manufacturer’s recommendation,
the “boost” cycle for sealed cells can be disabled by setting
the equalize setting switch to manual, if required.
Battery Charge Settings
Preset ProStar MPPT battery charging options are shown in
tables 4-1 and 4-2 below. All voltage settings listed are for
nominal 12 Volt batteries. Multiply the voltage settings by
two (2) for 24 Volt batteries.
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 parameters,
but only the battery manufacturer can recommend optimal
settings for their products.

Table 4.2. Battery settings that are shared among all battery types
The ProStar MPPT provides seven (7) standard battery
charging settings that are selected with the settings switches
(see Table 4.1 above). These standard charging settings
are suitable for lead-acid batteries ranging from sealed
(gel, AGM, maintenance-free) to Flooded and L-16 cells.
In addition, an eighth charging setting provides for custom
set-points using MSView
TM
PC software. Table 4-1 above
summarizes the major parameters of the standard charging
settings. The shared settings in Table 4-2 are common to
all battery types. The following charging profiles graphically
illustrate the shared settings:
