Phocos PLA Multi Charge Control

Phocos PLA Control Unit for Multi-PL Control

• Synchronizes up to 3 PLs
• Built-in 30 days data logger for the complete system
• Built-in RS232 interface
• Isolated alarm indication and outputs
• Suitable for great systems of up to 180 A


The PLA allows multiple PL series charge controllers to

work together in a single system. It provides a common
RS232 communication interface and four alarm/control
channel outputs; it can also control a LSI load switch unit.
The PLA can also be used as an autonomous alarm or in
combination of up to three PL charge controllers. For this
application PL controllers type PL 20, PL 40 and PL 60 can
be combined in any form. This leads to a powerful combination
for large stand alone solar and hybrid systems of up
to 180 Amps charge current.

The PLA makes the retrieval of system performance data
easier by providing total system information in addition to
the comprehensive data acquisition features of the PL
charge controllers. Communication is done via a galvanic
isolated RS232 serial port.
The unit has high and low battery voltage alarms with
alarm state indicators. The alarm levels are programmable.
The PLA keeps the individual PL controllers synchronized.
This results in properly charge sharing between controllers.
