Battery Setup B-01: Set Battery Voltage During initialization of OPTI-Solar SC MPPT Series, it will detect and ask the installer to confirm the battery voltage found is co rrect. In almost all circumstance the OPTI-Solar SC MPPT Series will correctly detect battery voltage. - Page 42 The above values are based on 12V system. The values x 2 are for 24V system; the values x 3 are for 36V system and the values x 4 are for 48V system. OPTI-Solar SC MPPT Series will charge at the Absorption voltage and at the length of time before switching to float mode.
- Page 43 B-07: Set Absorption Time Use Constant B-07 to adjust the length of Absorption time. The factory setting is 2 hours (displayed as 02:00). B-08: Set Float Voltage Use Constant B-08 to adjust the Float voltages. The default set values are based on the battery type and capacity selected.
