temperature reaches a high level.
(1) Upanel-Ubattery is limited to 40 V.
(2) Short circuit: >3x – 20x nominal current.
(3) Battery must be protected by a fuse, or it can be permanently damaged in case of a short
circuit. Remark: It is recommendable to use a fuse which amperage corresponds to the
nominal current of the charge controller. E.g. CIS-N-LED (10 A) needs a 10 A fuse.
(4) Reverse current through solar panel is blocked by serial MOSFET. This function is tested and
activated approx. one time in 1min +/-5s.
(5) The solar panel voltage should not exceed this limit for a longer period of time as surge
protection is present by varistor.
The combination of different error conditions may cause damage to the controller.
Always remove the error before you continue connecting the controller!
Low Voltage Disconnect Function (LVD)
State of charge (SOC) controlled: Disconnect 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):
Disconnect at a fixed voltage between 11.0/22.0 V and 11.9/23.8 V (Step 0.1/0.2 V).
