Phocos CX20-48V Solar Charge Controller for 24/48V solar systems
PV solar charge controller
The Phocos CX48 Series offers outstanding features for its class: along with a PWM charge controller with integrated temperature compensation, the CX controller comes equipped with an extensive range of control, programming and safety functions. The battery charge status is continuously displayed via a bar graph, including the input and output current of the battery as well as the load status (e.g. overloading, load short circuiting). The deep discharge protection mode has 5 settings: two fixed voltages, two charging states or adaptive (for battery protection). An audible alarm and a programmable nightlight function are standard on all CX controllers.
- LCD - Charge and discharge status display
- Audible alert before load disconnect
- Load status indication
- Choose between 5 load disconnect algorithms
- Four-stage PWM charging (series type)
- Integrated temperature compensation
- Full electronic protection
