INSTALLING A MULTI-CONTROLLER SYSTEM

A communication link is established between controllers by daisy chaining a twisted pair cable from the IPN Network terminal block, controller to controller
(A-to-A, B-to-B) as shown in Figure 5. Up to 8 IPN based charge controllers can be connected together in a multi-controller system. Device address 0 (zero) is the
master and 1 – 7 are slaves. The master controls the charging process and directs the activities of the slaves. The charge control system will start whenever
one or more controllers receives PV input power.

MULTI-CONTROLLER WIRING AND SETUP

CAUTION: A multi-controller system requires the following specialized installation and setup:
1) Each controller must connect to and charge the same battery.
2) One controller must be set to IPN address 0 (zero) and the others be set to addresses 1 – 7 with no controllers set the same.
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.
5) All controllers must be connected to the IPN network as shown in Figure 5.
Twisted Pair, 18 – 22 awg
IPN Network Address
A single controller must be set to IPN network address 0 (zero). In a multi-controller system one controller must be set to
address 0 (zero) to serve as the master. The other controllers must be set to address 1-7 with no two controllers set the same.
