Safety Features - Phocos CIS-N-MPPT 100/30 Betriebsanleitung

Testing Function
Pushing the test button on the CIS-CU (Control Unit) will swit ch on load terminal for 1 minute.
Should pressing the button cause a load disconnect event (LVD/SOC, overcurrent) then the load will be switched off
immediately.

Safety Features

Reverse polarity
Short circuit (3)
Overcurrent
Reverse current
Overvoltage
Undervoltage
Over temperature
(1) Panels are short circuited by diodes. So there is a limited time the controller can be subjected to these conditions. A
Battery connected to the panel terminals in reverse polarity will instantly cause a damage to the controller.
(2) Controller can protect itself, but any connected loads might be dam aged.
(3) Short circuit: >3x 20x n ominal current.
(4) Battery must be protected by a fuse, or it might be perm anently damaged in case of short circuit.
(5) >103% nomin al current: disconnect with 2 min. delay
>124% nominal current: disconnect with 40s delay
(6) MPPT switches off when detecting reverse current.
(7) At volt ages ab ove 95 V the MPPT will stop charging.
WARNING: The combination of different error conditions m ay cause dam age to t he controller. Always remove the fault
condition before you continue with connecting the controller!
Low Voltage Disconnect Function (LVD)
•
State of charge controlled (SOC): Disconnects at
11.00/22.00 V t o 11.70/23.40 V(SOC1), 11.12/22.24 V t o 11.76/23.52 V(SOC2),
11.25/22.50 V t o 11.83/23.63 V(SOC3), 11.38/22.72 V t o 11.89/23.78 V(SOC4),
11.51/23.02 V t o 11.96/23.92 V(SOC5), 11.64/23.28 V t o 12.02/24.04 V(SOC6).
•
Voltage controlled (LVD): Disconnects at a fixed voltage between 11.0/ 22.0 V and 11.9/23.8 V (voltage steps
0.1/ 0.2 V).
Note: Battery voltage must be below adjusted setting for longer than 2 minutes before LVD occurs.
Note: Voltage levels before/after the slash are valid for 12 V and 24 V systems resp ectively (valid for the charge
controllers presented in this manual).
