The equipment in the absence of testing in production works well, the appearance is of a well-designed and robust product, has a good cooling surface and we must bear in mind that it is a regulator with a certain quality, it is an MPPT equipment and according to my basic tests, it performs all loading stages perfectly.
I have done the tests in the workshop to check the real data with the multimeter and the truth is that all the data is real to what it shows on the screen, both the voltage, power and load data.
The basics (Battery type, working voltage, load operation mode) can be configured from the computer screen using the key combination indicated in the manual, only in English.
It comes with an RS232 to USB connection cable and is used to make more complex configurations and can only be enhanced using the software provided by the manufacturer. There is no CD for installation, you have to download it from the Renogy manufacturer's page.
The problem with this software is its installation on Windows 10 as it is my case, you have to make a series of steps because if it does not work, imagine that it is compatible only with previous versions of windows.
I explain a bit my experience to make it work in Windows 10 I have done the following.
First register the OCX controls that you install as it does not register it correctly, for that you have to go to the windows console, (CMD), and run it in administrator mode. Then record the five OCX controls:
regsvr32 c:\windows\syswow64\MsComm32.ocx
regsvr32 c:\windows\syswow64\MsComctl.ocx
regsvr32 c:\windows\syswow64\Tabctl32.ocx
regsvr32 c:\windows\syswow64\Comdlg32.ocx
regsvr32 c:\windows\syswow64\Mschrt20.ocx
once registered the OCX you have to modify the executable of the application that you will find inside the folder of the windows directory SysWOW64, (in my case C:\Windows\SysWOW64), press right mouse button on the executable "Solar Station Monitor.exe "and select the compatibility tab in the properties list of the file and modify the following:
Check "Run the program in compatibility mode" and select "Windows7"
Mark "Run this program as administrator"
Also remember and important, do not connect the USB to the PC without first having loaded the drivers that accompany the software that you download.
Once everything is installed the software should start and to use it you have to follow the steps of the manual that accompanies the software, the password for the administrator user is 111111.
Another fact to keep in mind is that it is supplied with an external temperature probe that is used to control the temperature of the battery bank and that the regulator can act accordingly.
I do not value the product with 5 stars for the problems not solved with the installation of the management program, but once installed it is very useful and works perfectly.
I recommend it without hesitation, good price, good quality and good BBB benefits.
