CAUTION: When PHI battery quantities change, the capacity & charge/discharge current settings
must to be reassessed. Failure to do so will void the Warranty.
4.3 – MPPT Charge Controller Settings
Solar charge controllers must be used in DC coupled systems to regulate the power produced by the PV
array that is delivered to the batteries. Schneider Electric offers two different MPPT charge controllers,
both of which are compatible with PHI batteries:
1. Conext MPPT 80 600
2. Conext MPPT 60 150
The 80 600 model is somewhat unique in that allows for larger strings of PV modules to be easily
installed and connected to the PHI battery bank. Charge controller selection depends on the system size
and personal preference; The recommended setpoints for either Schneider Electric charge controller are
the same.
SimpliPhi Power recommends the 80% DoD settings in Table 2.0 below in order to maximize the
Warranty. Additional settings are outlined based on Warranty and desired cycle life.

Notes:
• 1. Maximum setting of 48V limited by some inverter firmware is below the recommended setting.
• 2. Per PHI 3.8 kWh 48V battery – These settings are calculated by multiplying the nominal value per-battery value times
the # of batteries. For other batteries, refer to the Warranty and Specification Sheet for the specific model. Refer to
Charge Controller Bank Sizing under the “Battery Bank Sizing” section.
• 3. To calculate Max Charge Rate as a percentage, divide the calculated Max Bulk Current in Amps DC by the equipment’s
maximum potential charging current:

• Levels are typical @ 25⁰C and may need adjusting at temperature extremes.
• When performing rapid deep charge/discharge cycles the 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 be reassessed. Failure to do so will void the Warranty.
