The included software is java-based. The default password is "mpptsolar". If you don't have windows, the installer works under recent versions of Wine on linux. You will also need the rxtx library ("Java Serial Communications Revisited" by Jim Connors should get you to the right place--I'd recommend the JSSC software instead of rxtx, less crashes). Found on the internet, this is what I ended up using:
java -classpath $CLASSPATH:. cn.com.solargain.solar.console.MainConsole
That should get you connected.

This review is from: HXENGY 20/30/40amp MPPT Solar Charge Controller 12V/24V/48V 100VDC Input with PC RS232 Communication and Temp Sensor(40a)display almost useless, I could never figure out how to interpret it, although rated for 48v, it was useless for me at this voltage. I connected 2 in parallel as per their instructions, on a sunny day I got a grand power output of 3.5 kw for the day, I should have been able to get that much per hour from my system. I purchased a watt hour meter to check this out, it confirmed its lackluster performance. I connected my 24v panels in series of 2 with an open circuit voltage around 66v. I felt I needed to connect them 3 in series to get better performance, but the chargers are rated 100v max. These were a waste of my time. The software included dose not work on Linux systems. The setting buttons on the unit did not seem to work for me, and the English description of the set up, needs to be written by some one who could use English better. I purchased four returned them all, one of the four, was faulty, two did not charge sufficiently, the fourth I returned without opening the box. I am... Read more

If it works as good as their response in shipping I will continue to be very happy. We will be using it to maintain a charge of a 48 volt 155 amp hour battery bank to run a 12,000 BTU Full DC split air conditioning system on a solar equipped state-of-the-art research vessel.
