MULTI-CONTROLLER WIRING AND SETUP
¾ CAUTION: A multi-controller system requires the following specialized installation and setup:
1) Each controller must be a separately installed charging system and connect to and charge the same battery.
2) Attached Slave controllers must be set to addresses 1 – 7 with no two controllers set the same. (3000i is fixed to IPN address 0
and is the charge control Master.)
3) Charge parameters are set in the Master only.
4) While outputs connect in parallel to a common battery, PV inputs must be completely separate. A large PV array must be
divided into sub-arrays, each with separate PV+ and PV– wiring to their controller.
5) All controllers must be connected to the IPN network as shown in Figure 6.

TROUBLESHOOTING GUIDE
¾ If operational problems occur the single most important troubleshooting item is to be certain that battery voltage as measured
on the battery terminals of the 3000i is the same as voltage measured on the batteries themselves within a few 10 ths of a volt at
all times. If voltages are different there is a connection problem to the battery which often resides within the battery fuse or fuse
holder. The fuse holder feeling warm or hot during operation is a sure sign of a poor quality or failing fuse or fuse holder which
must be corrected. Once proper battery voltage is confirmed the second most important item to check is PV voltage on the PV
terminals of the 3000i. While PV voltage will vary greatly when the 3000i is in a Charge On state, the 3000i will not switch to a
Charge ON state unless PV voltage is at least 0.3V higher than battery voltage with everything connected in the normal manner.
SYMPTOM PROBABLE CAUSE ITEMS TO EXAMINE OR CORRECT
Completely dead,
display blank. No battery power.
Display mode set to OFF. Battery disconnected, overly discharged, or connected reverse polarity. Battery
powers 3000i, not PV. Voltage present on the 3000i’s battery terminals must be the
same as actual battery voltage within a few 10
ths and at least 9 volts.
Press Display Select to select display mode other than OFF.
Display very dim. 3000i in Charge Off state Normal operation, display automatically dims when 3000i is in Charge Off state even if
Slave(s) are in charge on state causing Float/ Absorption LEDs’ to be on.
All display segments
& LED indicators
stuck on. PV connected reverse polarity.
PV- connected to BAT- external to
controller causing unexpected ground
currents.
Immediately correct polarity.
PV- & BAT- must be separate for proper operation. External connection prevents
proper operation.
Unit will not switch to
Charge ON state. No battery power.
PV disconnected or low in voltage.
PV reverse polarity.
Microprocessor lockup.
Over temperature shutdown.
Battery disconnected, overly discharged, or connected reverse polarity. Battery
powers 3000i, not PV. Voltage present on the 3000i’s battery terminals must be the
same as actual battery voltage within a few 10
ths and at least 9 volts.
PV voltage when connected to the 3000i must be at least 0.3V greater than battery
voltage for 3000i to switch to Charge On State.
Reverse PV will heat front panel & force all display segments & LED’s ON.
Momentarily remove all power (battery & PV) to re-boot.
Normal operation will resume when the 3000i cools.
