Testing Function

Pushing the test button on the CIS-CU (Control Unit) will switch 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

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 damaged.
(3) Short circuit: >3x – 20x nominal current.
(4) Battery must be protected by a fuse, or it might be permanently damaged in case of short circuit.
(5) >103% nominal current: disconnect with 2 min. delay
>124% nominal current: disconnect with 40s delay
(6) MPPT switches off when detecting reverse current.
(7) At voltages above 95 V the MPPT will stop charging.
WARNING: The combination of different error conditions may cause damage to the 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 to 11.70/23.40 V(SOC1), 11.12/22.24 V to 11.76/23.52 V(SOC2),
11.25/22.50 V to 11.83/23.63 V(SOC3), 11.38/22.72 V to 11.89/23.78 V(SOC4),
11.51/23.02 V to 11.96/23.92 V(SOC5), 11.64/23.28 V to 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 respectively (valid for the charge
controllers presented in this manual).
