ITEMS TO EXAMINE OR CORRECT
Check Float voltage setpoint.
Battery is highly discharged or very large relative to relative to available net charge
current. PV power may be too low or loads too high.
Normal operation. Unit will stay in Float and not switch to Bulk or Acceptance until it
is unable to hold the battery at the Float voltage setpoint.
Battery not fully charged. Unit will not switch to Float until battery voltage remains at
the Acceptance voltage setpoint continuously for the Charge Time period (or net
battery current drops to the Float Transition Current setpoint if using IPN-
ProRemote).
Normal operation. If the unit enters current limit, it will pass through Acceptance for
about 10 seconds upon exiting current limit and returning to Bulk/MPPT.
Confirm dip switch #4 is ON.
Load will shut off if battery voltage drops below OFF threshold (default 11.5/23.0V).
Once shut off, the load will turn on until battery voltage is above ON threshold
(default 12.6/25.2V).
Correct settings.
Disable Dusk-to-Dawn control.
Confirm dip switch #4 is ON and Dusk-to-Dawn enabled.
Load will shut off if battery voltage drops below OFF threshold (default 11.5/23.0V).
Once shut off, the load will not come back on until battery voltage is above ON
threshold (default 12.6/25.2V).
Lights will not turn on if charge control system is ON and charging.
Check Post-Dusk and Pre-dawn timer settings
Pre-Dawn lighting will not operate until a valid night time of greater than 2 hours is
detected to initialize the night time period.
Confirm dip switch #4 is ON and Dusk-to-Dawn enabled.
Post-Dusk and Pre-dawn timers both set to DISABLED. One or both timers must be
set to enable Dusk-to-Dawn feature.
Correct Post-Dusk and Pre-dawn timer settings.
Check charge control operation
A single unit must be set to IPN network address 0 (zero).
One unit of a multi-unit network must be set to IPN network address 0 (zero), AND
all other units must be set to different addresses.
Confirm wiring. Use IPN-ProRemote to View Charge Unit Status and confirm
communication.
If sensor is open, short, reverse polarity or missing unit will operate as if sensor was
at 25°C. Sensor voltage when connected should be 2.98V at 25°C, changing at
+10mV/°C.
Temperature sensor must be installed on the master in a multi-controller system.
Cable faulty
One charge controller only must be Master.
Poor or missing Bat – connections preventing communication
Configure display IPN network address to a charger present on the IPN network.
