Notes:
1. SimpliPhi recommends programming equpment as outlined in Table 1.0 above in order to maintain 80% DoD levels. Programming to
90% DoD (49.6V / 24.8V / 12.4V) and 100% DoD (48V / 24V / 12V) levels are permissable, but result in shorteneed cycle life (refer to
the PHI Battery Warranty for more information).
2. Sell Voltage parameter appears in the OutBack Radian inverter only.
• Levels are typical @ 25°C 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.
4.2.1 – Mini Grid Mode & Settings
According to the OutBack Radian Series Inverter/Charger Operator’s Manual:
“In Mini Grid mode, the Radian inverter automatically rejects an AC source and runs solely from battery
(and renewable) energy. The inverter only connects to the AC source (the utility grid) when the batteries
run too low… The inverter will reconnect to the utility grid if the battery voltage decreases to the
Connect
to Grid set point after the Delay time period.”
By programming Mini Grid Connect to Grid to 50.4V and Mini Grid Delay to 2 minutes, the Radian allows
the batteries to discharge to about 80% DoD. A voltage of 50.4V is typically the recommend voltage
setting for the
Connect to Grid parameter.
In Mini Grid mode and while connected to the utility grid, “the inverter’s charger can be set either On or
Off. If the charger is turned on, the inverter will proceed through a full charging cycle. Upon reaching the
end of the charging cycle, the inverter will disconnect from the grid.”
4.2.2 – Grid Zero Mode & Settings
According to the OutBack Radian Series Inverter/Charger Operator’s Manual:
“In Grid Zero mode, the Radian inverter remains grid-connected, but prioritizes the use of battery or
renewable sources to run loads. It uses only renewable energy to recharge the batteries… Any time the
