Most, if not all, inverters have related features. These features are often referred to as “Load Disconnect”,
“Load Shedding” or similar. These features are there to protect the battery bank from excessive discharge.
In instances of low battery voltage, when there is no incoming energy to recharge the battery bank, the
inverter will disconnect the load and remain in standby until the battery bank is recharged.
For Off Grid installations, where charge energy is only provided by PV arrays, Inverter “Load Disconnects”
are generally set at a value that will allow a system to remain online and in standby for at least 24 hours
(10% at top of charge and 10% at bottom of charge). This allows a system to stay online until at least one full
day of sun can recharge the battery bank.
In any application, off-grid or grid-tied, if your
PHI2.6™
battery bank is reaching the LBCO, load disconnects
or load shedding set points may need to be adjusted.
In case of LBCO, cycle the DC Battery Disconnect (inverter), in order to reset the system. Only complete
this procedure when there is a charge source available, otherwise, the system will simply reach LBCO in a
short time period and shut down again.
SimpliPhi Power GUIDE FOR OPERATING PARAMETERS PER WARRANTY
Although SimpliPhi batteries are capable of performing at very high rates and depths of discharge
within a very wide temperature range, in order to achieve extended life cycles and to comply with the
Warranty, the following guidelines should be followed:
Discharge/Charge Rate: C/2 (2 hour)
Recomended Programmed Voltages of Ancillary Equipment For 5,000 Cycles:
• Recharge or Low Cut-Off Voltage: PHI 24V: 23.2V; PHI 48V: 46.4V
• Absorb or High Cut-Off Voltage: PHI 24V: 28.8V; PHI 48V: 57.6V
Recomended Programmed Voltages of Ancillary Equipment For 10,000 Cycles:
• Recharge or Low Cut-Off Voltage: PHI 24V: 24.5V; PHI 48V: 48.9V
• Absorb or High Cut-Off Voltage: PHI 24V: 28V; PHI 48V: 56V
Rates of Continuous Discharge and Charge:
• Discharge: 30 Amps
• Charge: 30 Amps
• Storage must be equal to or more than twice the rated output of the Inverter
Operating Temperature Range Per Warranty:
• 23

Cycle Life
• Equivalent to 80% Retained Capacity
Caution: Verify polarity at all connections before energizing
system. Reverse polarity at the battery terminals will void the
Warranty and destroy the batteries.
Before commissioning the system the appropriate controller and inverter settings must be programmed
per the manufacturer’s recommendations. Consult the manufacturer’s manuals and/or access technical
support (Schneider, SMA, Magnum, Outback, etc). The following Charge Controller Integration tables
are for general reference only.
