SYMPTOM

PROBABLE CAUSE

ITEMS TO EXAMINE OR CORRECT

System appears OK,
but will not correctly
switch between Bulk,
Acceptance & Float

Not set for 3 stage charge

System will not switch out of Bulk and into
Acceptance or Float

System will not switch from Float to Bulk
or Acceptance

System will not switch from Acceptance to
Float

System shows Acceptance at times but
battery voltage is low and current is very
high near max. rating.

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.

Load control not
working properly

Auxiliary output not set for load control

Output may have shut off due to low
battery charge

ON/OFF thresholds set to inappropriate
values

Dusk-to-Dawn feature enabled

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.

Dusk-to-Dawn
feature, lights will not
turn ON or remain
ON

Auxiliary output not set for load control

Output may have shut off due to low
battery charge

Charge control system ON

Timers set incorrectly

First valid night time not seen yet

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.

Dusk-to-Dawn
feature, lights will not
turn OFF or remain
OFF

Auxiliary output not set for load control

Dusk-to-Dawn feature not enabled.

Timers set incorrectly

Charge control does not turn ON

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

Networked units do
not seem to
coordinate action or
slaves do not turn on

IPN network address set wrong


Network wiring problem

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.

Temperature related
functions do not
work.

Temperature sensor missing, failed or
installed reverse polarity

Temperature sensor not installed on
master

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.

Display turns on, but
battery voltage
displays “– – –“
rather than a number

Display not communicating with charge
controller

Cable faulty

One charge controller only must be Master.

Poor or missing Bat – connections preventing communication

When charger turns
on, output current
displays “– – –“
rather than a number

Output current display selection set for an
address not present on the IPN network

Configure display IPN network address to a charger present on the IPN network.
