CXNup — PWM charge controller with LCD 10–40 A
Country: Germany · Model: CXNup
A backlit LCD, SOC indication and a USB output distinguish this 10, 20 or 40 A PWM charge controller for 12 and 24 V solar systems. It is chosen for houses, cottages, camping and solar lighting where the battery status should be visible without a smartphone or computer.

Description
The display shows the battery charge level, and the built-in log stores data for up to 2 years of system operation. A phone or tablet is charged through the USB output directly from the battery. The controller recognizes the 12 or 24 V voltage automatically. The PV input is rated 30 or 50 V, so it works with modules whose rating matches the bank voltage, without long series strings. For street lamps there are programmable load control modes. The IP22 enclosure is mounted indoors, on a wall next to the battery. The controller carries CE and RoHS marking.
How to choose
The rating is chosen with a margin over the short-circuit current of the array, which is why the range has three steps, CXNup10, CXNup20 and CXNup40. If the module voltage exceeds 50 V or the bank is built for 48 V, PWM is no longer suitable and an MPPT controller, the CX-N-MPPT (30 or 60 A), is needed. For outdoors with dust and moisture, take the sealed CIS-N (10 or 20 A) with an IP68 enclosure.

FAQ
What does the CXNup controller display show?
The backlit LCD shows the SOC charge status and the operating parameters of the system. The data log stores up to 2 years of history.
What maximum solar panel voltage does the CXNup allow?
Up to 30 or 50 V at the PV input. Modules are connected so that the string voltage does not exceed this limit even in frost.
Can a phone be charged from the CXNup controller?
Yes, the controller has a USB output powered from the 12 or 24 V battery.
Is the CXNup suitable for solar street lighting?
Yes, it has programmable street lighting modes. However, the IP22 enclosure must be placed in a protected box on the pole.
How do the CXNup10, CXNup20 and CXNup40 models differ?
By the rated charge and load current, 10, 20 and 40 A respectively. The battery voltage of 12 or 24 V and the PV input of 30 or 50 V are the same in all of them.
