0°C (32°F) the equalization voltage will reach 67.00 Volts for L-16 batteries with a temperature
sensor installed. Disconnect any loads at risk of damage due to the high input voltage.
If Hydrocaps are used, be sure to remove them before starting an equalization. Replace the
Hydrocaps with standard battery cell caps. The Hydrocaps can get very hot during an equaliza-
tion. Also, if Hydrocaps are used, the equalization should be set for manual only (DIP switch #7
is Off).

Equalize a Sealed Battery?
The
Battery Charging Settings
table (see table 4-1 in this section) shows one sealed battery set-
ting with an Equalization cycle. This is only a 0.4 Volt boost cycle to level individual cells. This is
not an equalization, and will not vent gas from sealed batteries that require up to 57.60 V charg-
ing (48 V battery). Many VRLA batteries, including AGM and gel, have charging requirements up
to 57.6 V (48 V battery). This “boost” charge for sealed cells can be disabled by setting the equal-
ize setting switch to manual if required.
Battery Charging Settings
The details of the TriStar MPPT 600V battery charging settings are shown in tables 4-1 and 4-2
below. All voltage settings listed are for nominal 48 Volt battery banks.

Table 4-2. Battery settings that are shared between all battery types
The TriStar MPPT 600V provides seven (7) standard battery charging settings that are selected
with the settings switches (see Step 9 in the Installation Section). These standard charging set-
tings are suitable for lead-acid batteries ranging from sealed (gel, AGM, maintenance-free) to
Flooded and L-16 cells. In addition, an 8th charging setting provides for custom set-points us-
