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:

06D Max Charge Time 12 Hrs.
06E Bulk Start
Daily/SunUp YES, to set the PT-100 to start a Bulk charge cycle each new day at sun-up
Bulk Start Volts 25.5V / 51V

ME-BMK is required for this setting
06G PT Alarm PT controller can be programmed for a low battery voltage alarm
Notes:
1. Per PHI 3.8 kWh battery – These settings 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.
