Mine is 200VDC/100A and is connected to 4 parallel strings of 4 72 series honeycomb panels. 295 Wp/cell each. I ran through 1.6 megawatts. The battery voltage is easy to set for lithium batteries. The RS485 package allows me to save data to a PC using the eLOG01 unit (sold separately). The radiator heats up in sunny weather so I mounted it on a steel base plate, fans help with that. The MT50 value is great for monitoring. There really isn't a good way to read data into a remote web application. Bluetooth and Wi-Fi are only good for nearby communication. otherwise it's a great article. If I expand my system, I will buy another one.
