Preparation for Equalization
First, conrm that all of the system loads are rated for the equalization voltage. Consider that at
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).
After the equalization is nished, add distilled water to each cell to replace gassing losses.
Check that the battery plates are covered.
Equalize a Sealed Battery?
The Battery Charging Settings table (see table 4-1 in this section) shows one sealed bat-
tery setting 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 charging (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 equalize setting switch to manual if required.

Table 4-2. Battery settings that are shared between all battery types
The TS-MPPT-600V-TR 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-
