4.2 – Charge Controller Settings
Please review Table 2.0 below for Midnite Solar charge controller program settings. To initiate a factory
reset, hold left & right arrow buttons while turning on Battery Breaker. This is normally only done for initial
setup, as doing so will erase all custom settings.

Notes:
• 1. Per PHI battery – Refer to Section 3.0 herein for charge controller PHI battery bank sizing.
• 2. Per PHI battery – These settings are calculated by multiplying the nominal value per each PHI battery times
the # of PHI batteries. For other batteries, refer to the Warranty and Specification Sheet for the specific model.
• 3. End Amps settings only work when the “Midnite Whiz Bang Jr & 500A/50mV shunt” are installed. When the
Whiz Bang Jr is used, Aux 2 is not available for a turn off signal from auxiliary source.
• Levels are typical @ 25°C and may need adjusting at temperature extremes.
• When performing rapid deep charge/discharge cycles, the PHI battery should be allowed to "rest" 15 minutes in
between.
• Always refer to the SimpliPhi Power Manual and Warranty for the specific PHI battery model.
CAUTION: When PHI battery quantities change, the capacity & charge/discharge current settings
must to be reassessed. Failure to do so will void the Warranty.
