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. Magnum Energy offers one MPPT charge controller, the PT-100,
which is compatible with PHI batteries:

PT controller can be programmed fo a low battery voltage alarm
Notes:
1. Per PHI 3.8 kWh battery – These setting are calculated by multiplying the nominal per-battery
value times the number of batteries.
2. The maximum programmable setting of 48.8V is below the recommended LBCO setting. To
maintain the batteries at a maximum 80% or 90% DOD, utilize the 02D AC In – VDC setting for
grid backup.
3. Per PHI 3.8 kWh battery and as a percentage of the inverter’s or charge controller’s maximum
charge rating – These settings are calculated by multiplying the nominal per-battery value times
the number of batteries, then divide by the equipment’s maximum charging current.

• Levels are typical @ 25C 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.
CAUTION: When PHI battery quantities change, the capacity and charge/discharge current settings
must be reassessed. Failure to do so will void the Warranty.
