* These power levels refer to the maximum wattage the
SS-MPPT-15L can process at a certain system voltage. Higher
power arrays can be used without damaging the controller, but array
cost-benet will be reduced at power levels much beyond the nominal
ratings.

Adjustable by switch, not temperature compensated. 11.0V / 12.1V setting
can be modified in custom settings.
NOTE: Temperature compensation increases regulation
voltage in cold temperature. A 15V (30 V @ 24V nominal)
maximum battery voltage limit prevents damage to
sensitive DC loads.
