Table 4-2. Battery settings that are shared between all battery types
The TriStar MPPT 150V provides seven (7) standard battery charging settings that are selected
with the settings switches (see Figure 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 8th charging setting provides for custom set-points using MSView
TM
PC soft-
ware.
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proles
