PROBABLE CAUSE ITEMS TO EXAMINE OR CORRECT
Confirm Float voltage setpoint is not set to OFF.
Available net charge current cannot bring battery voltage up to the present charge voltage
setpoint. Battery state of charge may be too low, battery too large, PV power too low,
and/or loads too high. PV's should produce at least 3 amps per 100 amp-hours of battery –
and– daily PV amp-hours produced must be greater than daily load amp-hours consumed.
Battery not fully charged. Unit will not switch to Float until 3000i remains in Absorption
continuously for the Absorption Charge Time period.
Periodic load pulls battery voltage low causing 3000i to re-enter Bulk resetting the
Absorption Charge Timer. Consider using a shorter Absorption Charge Time setting.
Momentary decrease in PV power allows battery voltage to drop causing 3000i to re-enter
Bulk resetting the Absorption Charge Timer.
Install battery temperature sensor BSE p/n 930-0022-20.
Use only BSE battery temperature sensor p/n 930-0022-20.
If sensor is open, short, reverse polarity or missing 3000i will operate as if battery
temperature is 25C. Proper sensor voltage when excited by the 3000i will read approximately
2.98V at 25C, changing at +10mV/C.
Confirm "out" setting is set to "ch9".
Auxiliary battery will not receive charge unless primary battery is in Absorption or Float.
Maximum auxiliary charge current is roughly 2 amps. Load may need to be reduced.
Confirm proper connection.
Confirm proper connection.
If auxiliary battery connection is open, value may float around a few 10ths of a volt.
Confirm "out" setting is set to "Lod".
Load will shut off if battery voltage drops below OFF threshold (default 11.5V). Once shut
off, the load will not come back on until battery voltage is above ON threshold (default
12.6V) for 20 seconds.
Correct ON/OFF threshold settings.
Load will shut off if lighting control enabled and 3000i is in Charge On state.
Confirm "out" setting is set to "Lod".
Load will shut off if battery voltage drops below OFF threshold (default 11.5V). Once shut
off, the load will not come back on until battery voltage is above ON threshold (default
12.6V) for 20 seconds.
Lights will not turn on if charge control system is ON and charging as this is day time.
Check time settings of Post-Dusk or Pre-dawn timer.
Pre-Dawn lighting will not operate until a valid night time period of 4 hours detected. If PV
was removed/reconnected, night time period may be inaccurate. Remove & restore battery
& PV power to reboot.
Confirm "out" setting is set to "Lod".
Either Post-Dusk or Pre-dawn timers must be set to time value to enable Dusk-to-Dawn
feature.
Check charge control system related items.
Disable dimming feature or correct setting.
One unit of a multi-unit network must be set to IPN network address 0 (zero) to be charge
control Master, AND all Slave units must be set to different addresses 1 – 7.
Confirm wiring correctly in place. Use IPN ProRemote or UCM to see View Charge Unit
Status screens to confirm communication with slaves.
Check charge control related items on Slave. Consider temporarily removing Slave unit from
network and setting unit to be standalone Master for troubleshooting.
