Interface and data logger with MXI/MXI232 and CXLink
The controller comes with one serial interface which can be connected to a PC with the
optional interface adapter MXI/MXI232 (see interface adapter manual for details) and the
CXLink software.
The CXup controller features a built-in data logger. The data logger registers up to 2 year
performance data of your PV system, including charge Ah, load Ah and SOC in the morning etc.
System performance can easily be analyzed with the aid of this history, thus helping the user to
get to know the PV system better.
With the MXI/MXI232 and CXLink application software, the CXup data logger can be accessed
by a computer. Performance data can be read and displayed with the aid of CXLink.
External Temperature Sensor
With the temperature sensor (type NTC) the CXup can measure the battery temperature and
adjust the charging voltage accordingly and thus extend the battery lifespan.
